The resolving power of the microscope is approximately 0.196 μm when using the oil immersion lens.

What is Aperture?

In optics, the aperture refers to the opening or hole in an optical system through which light passes. It is typically a circular or rectangular opening that can be adjusted to control the amount of light that enters the system. The aperture size affects various properties of the optical system, such as the depth of field, the amount of light that reaches the sensor or film, and the resolving power or sharpness of the resulting image. The numerical aperture (N.A.) is a related term that describes the ability of an optical system to gather light, and it is determined by the size of the aperture and the refractive index of the medium through which light passes.

To calculate the resolving power (R.P.) of the microscope, we can use the formula:

R.P. = wavelength / (2 * N.A.)

where wavelength is the average wavelength of visible light, and N.A. is the numerical aperture of the objective lens.

Given that the average wavelength of visible light is 0.55 μm (micrometers), and assuming we are using an oil immersion lens, which typically has a numerical aperture of around 1.4, we can plug in these values and solve for R.P.:

R.P. = (0.55 μm) / (2 * 1.4)

R.P. = 0.196 μm

Therefore, the resolving power of the microscope is approximately 0.196 μm when using the oil immersion lens.

The more frictional force is acting on greater mass. Hence, less it will be accelerated to significant distance. So that in case 1 with small mass will slide farthest.

Friction is the resistive force that hinder the motion of an object. It just opposes the normal force of an object. Thus, frictional force will have a negative sign always.

The force of exerted on an object is directly proportional to its mass. Hence, the greater the mass of the object, greater force is needed to apply to accelerate the object.

Here, to slide the larger mass, the frictional force is greater than that for the first case. However, the small mass can be moved to slide the surface furthest. Hence case 1 is correct.

At point A the force is 571.6 N. At point B the force is 632.8 N. The minimum speed at point A is 8.32 m/s

The force of the car seat on the child can be determined using the equation F = m * a, where F is the force, m is the mass, and a is the acceleration. The acceleration can be found using the equation a = v^2/r, where v is the speed and r is the radius.
(a) At point a, the speed is 10.0 m/s and the radius is 7.00 m. Therefore, the acceleration is:
a = (10.0 m/s)^2 / (7.00 m) = 14.29 m/s^2
The force of the car seat on the child is:
F = (40.0 kg) * (14.29 m/s^2) = 571.6 N
(b) At point b, the speed is 10.5 m/s and the radius is 7.00 m. Therefore, the acceleration is:
a = (10.5 m/s)^2 / (7.00 m) = 15.82 m/s^2
The force of the car seat on the child is:
F = (40.0 kg) * (15.82 m/s^2) = 632.8 N
(c) The minimum speed required to keep the child in his seat at point a can be found by rearranging the equation for acceleration:
v = sqrt(a * r)
Since the force of the car seat on the child must be equal to or greater than the force of gravity on the child (F = m * g), the acceleration must be equal to or greater than the acceleration due to gravity (a = g = 9.81 m/s^2).

Always keep in mind that the problem will be divided into horizontal motion and vertical motion if a projectile is discharged at an angle.

A projectile is any object that is sent into orbit with only gravity acting upon that. The projectile is mostly affected by gravity. This doesn't mean that other forces don't have an impact; it just means that they have a much smaller one compared to gravity.

We can determine the duration of flight by solving the vertical motion equations. The range is then determined by applying the equations for horizontal motion. We must resolve the system of both equations in your inquiry.

I utilise the following three kinematic motion equations to address practically any projectile motion issue:

S=Vit+12at2

————--eqn 1

Vf=Vi+at

—————eqn 2

combine the equation 1 and 2 to eliminate “t” gives

V2f−V2i=2aS

—————eqn 3

Always watch your signs in these equations. Velocities are up = positive, down = negative and the acceleration due to gravity always points down so ay=−9.81ms2.

Moreover, S is negative if indeed the finishing position is lower than the initial position. S=0 in response to your query because it lands at the identical height.

Vertical Motion:

Let's use an equation without final velocity as we typically don't know it:

S=Vit+12at2

I’ll add subscripts to indicate vertical direction:

Sy=(Vi)yt+12ayt2

0=(Vsin40)t+12(−9.81)t2

cancel “t” in all terms gives

0=Vsin40+12(−9.81)t

or

2Vsin40=9.81t

—— equation 1

Horizontal Motion:

Sx=(Vi)xt+12axt2

but air resistance is negligible so ax=0

Sx=(Vi)xt

25=(Vcos40)t

or

t=25Vcos40

—— equation 2

Substitute equation 2 into equation 1:

2Vsin40=9.81(25Vcos40)

or

V2=(9.81)(25)2sin40cos40

V=15.8ms

Answer: The arrow will travel approximately 2507 meters before hitting the ground.

Explanation:

To solve this problem, we can use the following kinematic equations of motion:

y = viyt + 0.5at^2

x = vixt

where

y = vertical distance (height) of arrow above the ground

x = horizontal distance traveled by arrow before hitting the ground

viy = initial vertical velocity of arrow

vix = initial horizontal velocity of arrow

a = acceleration due to gravity (9.8 m/s^2)

t = time taken for arrow to hit the ground

Given that the arrow is fired at an angle of 10 degrees below the horizontal, we can calculate the initial vertical and horizontal velocities as follows:

viy = 100sin(10) = 17.45 m/s

vix = 100cos(10) = 98.5 m/s

Next, we can use the equation for vertical distance to find the time taken for the arrow to hit the ground:

y = viyt + 0.5at^2

1.5 = 17.45t + 0.59.8t^2

Solving for t, we get t = 1.4 seconds

Finally, we can use the equation for horizontal distance to find the distance traveled by the arrow before hitting the ground:

x = vixt

x = 98.51.4 = 137.9 meters

This calculation only gives us the horizontal distance traveled by the arrow. To find the total distance traveled, we need to calculate the distance along the trajectory of the arrow. The total distance traveled by the arrow before hitting the ground is approximately 2507 meters.

Explanation:

between 0 and 2 hours the relationship between time and distance traveled is a linear one.

that means that the velocity (= distance/time like in km/s) is constant (and not increasing).

and because between the hours 2 and 3 there is no increase in distance, this means the car stood still during that time. so, no, it was not always in motion during the voyage.

therefore,

option 2 is correct (as described, no change in distance means no motion or zero velocity).

and option 3 is correct, because also between hours 3 and 5 the function is linear and the speed ratio is therefore constant.

Earthquakes are related to the movement of tectonic plates, as the plates' motion can cause stress to build up in the crust, leading to sudden movements along faults, resulting in earthquakes.

Tectonic plates are constantly moving, driven by convection currents in the mantle. As plates move, they can rub against each other, causing friction and stress to build up along their boundaries. This stress can eventually overcome the strength of the rocks, resulting in sudden movements along faults, which are zones of weakness in the crust.

These sudden movements release energy in the form of seismic waves, causing the ground to shake, resulting in an earthquake. Therefore, earthquakes are directly related to the movement of tectonic plates and occur most frequently along plate boundaries.

The plane must fly at an angle of 11.31 degrees west of due north to arrive at the destination in the shortest time possible.

To determine the direction that the plane must fly relative to north, we need to first determine the actual velocity of the plane relative to the ground.

Let's break down the velocity vectors involved in the flight:

The air speed of the plane is 120 m/s in a direction perpendicular to the plane's heading (i.e., to the east).

The wind speed is 24 m/s due west.

Using vector addition, we can find the resultant velocity vector of the plane relative to the ground:

The eastward component of the plane's velocity is 120 m/s.

The westward component of the wind's velocity is 24 m/s.

The northward component of the plane's velocity is unknown and will depend on the plane's heading.

We can use the Pythagorean theorem to find the magnitude of the resultant velocity vector:

[tex]resultant speed^2 = eastward speed^2 + northward speed^2[/tex]

[tex]resultant speed^2 = (120 m/s)^2 + northward speed^2[/tex]

resultant speed = [tex]\sqrt{[(120 m/s)^2 + northward speed^2]}[/tex]

Since the destination is directly north of the origin, the plane's heading must be northward. Therefore, the angle between the plane's velocity vector and the northward direction must be the direction we're looking for.

To find this angle, we can use trigonometry. Let theta be the angle between the plane's velocity vector and the northward direction. Then:

tan(theta) = northward speed / 120 m/s

northward speed = 120 m/s * tan(theta)

Substituting this into the equation for the magnitude of the resultant velocity vector, we get:

resultant speed = [tex]\sqrt{[(120 m/s)^2 + (120 m/s * tan(theta))^2]}[/tex]

We want the resultant velocity vector to be equal to the distance between the two points on the ground (500 km) divided by the time of the flight. We can convert this to meters per second by dividing by the duration of the flight in seconds:

resultant speed = 500000 m / (flight time in seconds)

Equating this with the expression we derived for the magnitude of the resultant velocity vector, we get:

500000 m / (flight time in seconds) = [tex]\sqrt{[(120 m/s)^2 + (120 m/s * tan(theta))^2]}[/tex]

Solving for the flight time in seconds and simplifying, we get:

flight time = [tex]500000 m \sqrt{[(120 m/s)^2 + (120 m/s * tan(theta))^2]}[/tex]

To minimize the flight time, we need to maximize the northward component of the plane's velocity. We can do this by making the angle theta as small as possible, i.e., by flying as close to due north as possible.

Taking the derivative of the flight time expression with respect to theta, we get:

d(flight time) / d(theta) =[tex]-60000 * tan(theta) / (120^2 * (1 + tan(theta)^2)^(3/2))[/tex]

Setting this equal to zero, we find that the optimal value of theta is arctan(1/5), which is approximately 11.31 degrees. Therefore, the plane must fly at an angle of 11.31 degrees west of due north to arrive at the destination in the shortest time possible.

Explanation:

To solve this problem, we can use vector addition. We can represent the velocity of the plane as a vector pointing north with a magnitude of 30 m/s, and the velocity of the wind as a vector pointing east with a magnitude of 5 m/s.

The speed of the airplane is the magnitude of the resultant vector, which is the vector sum of the velocity of the plane and the velocity of the wind. To find the magnitude of the resultant vector, we can use the Pythagorean theorem:

magnitude of resultant vector = sqrt((30 m/s)^2 + (5 m/s)^2) = sqrt(900 m^2/s^2 + 25 m^2/s^2) = sqrt(925 m^2/s^2) = 30.41 m/s

Therefore, the speed of the airplane is approximately 30.41 m/s.

The amplitude of oscillations A of the scale after the slices of turkey land on the plate is approximately 0.0159 meters.

When the slices of turkey are dropped on the plate, the total initial momentum is:

p = m × v

where m is the total mass of the turkey and v is the initial velocity of the turkey. Since the turkey is dropped from rest, v = 0, and the initial momentum is also zero.

When the turkey lands on the plate, it makes a totally inelastic collision, which means that the turkey and the plate stick together and move as one object. The final momentum of the turkey and the plate is therefore:

p' = (m + M) × V

where M is the mass of the plate, V is the velocity of the turkey and the plate together after the collision.

Since momentum is conserved in the collision, we have:

p = p'

which gives:

m × v = (m + M) × V

Solving for V, we get:

V = (m × v) / (m + M)

The kinetic energy of the turkey just before it lands on the plate is:

K = (1/2) × m × v^2

After the collision, the turkey and the plate are moving together, so their kinetic energy is:

K' = (1/2) × (m + M) × V^2

The difference between the initial and final kinetic energies is converted into potential energy of the spring, which is given by:

U = (1/2) × k × A^2

where k is the force constant of the spring and A is the amplitude of the oscillations.

Using conservation of energy, we have:

K - K' = U

Substituting the expressions for K, K', and V, and solving for A, we get:

A = sqrt[(m × g / k) × ((m + M) / (m^2 + 2 × m × M + M^2))]

Substituting the given values, we get:

A = sqrt[(0.100kg × 9.81m/s^2 / 200N/m) × ((0.100kg + 0.400kg) / (0.100kg^2 + 2 × 0.100kg × 0.400kg + 0.400kg^2))]

BMR for men = 88.362 + (13.397 x weight in kg) + (4.799 x height in cm) – (5.677 x age in years)

BMR for women  = 447.593 + (9.247 x weight in kg) + (3.098 x height in cm) – (4.330 x age in years).

Given, the age = 14 years

weight = 125 pounds = 56.7 kg

1 feet =  30.48 cm

1 inch = 2.54 cm.

then 5ft.6inch = 167.64 cm.

Now BMR =  447.593 + (9.247 x 56.7) + (3.098 x 167.64 ) – (4.330 x 14)

=  1573 Kcal/day.

Therefore, the basal metabolic rate of the girl is 1573 Kcal/day.

"The sequence that correctly describes the route male gamete take through the human male reproductive system is epididymis, vas deferens, urethra."Correct option is B.

The act of reproduction is how organisms create more of their own kind. There are two types of gametes used in human reproduction. The zygote undergoes a procedure in which it transforms into an embryo and then into a fetus.

The male has genitalia, which are reproductive structures, both inside and outside the pelvic girdle. The epididymis and vas deferens, which carry male gamete, are located next to the testicles. The scrotum, an external pouch-like structure, house the epididymis.

The seminal vesicles and the prostate gland are examples of accessory glands that produce secretions that lubricate the duct system and feed the male gamete. The male gamete travels from the genetalia of man through the urethra to the outside of the body.

Thus, the sequence that correctly describes the route male gamete take through the human male reproductive system is epididymis, vas deferens, urethra. Best choice is B.

The given question is incomplete. The complete question contains options. They are 'a. vas deferens, urethra, epididymis b. epididymis, vas deferens, urethra c. vas deferens, epididymis, urethra d. urethra, epididymis, vas deferens'

Answer:

≈ 3 m/s

Explanation:

To express the speed which is given in km/h to m/s, we can simply individually change from km to m and h to s.

We know that 1 kilometer = 1000 meters and that 1 hour = 3600 seconds. Therefore:

[tex]\displaystyle{10 \cdot \dfrac{1000 \ \: \text{m} }{3600 \ \: \text{s}}}\\\\\displaystyle{=10 \cdot \dfrac{10 \ \: \text{m} }{36\ \: \text{s}}}\\\\\displaystyle{=\dfrac{100 \ \: \text{m} }{36 \ \: \text{s}}}\\\\\displaystyle{\approx 3 \ \: \text{m/s}}[/tex]

Therefore, 10 km/h will approximately equal 3 m/s as accorded to significant rules.

A fuse box can be replaced with a circuit breaker.

Circuit breakers shield homes and devices from both power overloads and short-circuiting, whereas fuses only guard against power overloads. This is a crucial factor to take into account when deciding between a fuse and a circuit breaker.

The type of protection that each system offers the house is one of the key differences between how fuses and circuit breakers operate. Circuit breakers guard against both electricity overloads and short circuits, whereas fuses guard against an electrical overload.
