Answer:

He collected many specimens of the finches on the Galapagos Islands. These specimens and his notebooks provided Darwin with a record of his observations as he developed the theory of evolution through natural selection.

Answer:

Explanation:

Power is defined as the rate at which work is done

Power = work/time and is measured in Watts

To find velocity, you need to divide the distance traveled and the time it took to travel that distance.

Velocity is a vector quantity that indicates the rate of change of an object's position in a given direction. It is calculated by dividing the change in position of an object by the time interval over which the change occurred.

The formula for velocity is,

velocity = distance / time

For example, if a car traveled 100 meters in 10 seconds, the velocity would be,

velocity = 100 meters / 10 seconds

velocity = 10 meters per second

The height of the building is 42.4 meters.

Let's call the height of the building "h". We can use the following kinematic equations to solve for "h":

For the stone that is dropped from the top of the building:

h = (1/2)gt² (Equation 1)

For the stone that is thrown upwards from the ground:

y = vt - (1/2)gt² (Equation 2)

where;

We know that the two stones meet at exactly 5s after their release. This means that the distance travelled by the stone thrown upwards from the ground is equal to the height of the building, i.e.,

y = h

We can substitute this equation into Equation 2 and rearrange it to solve for "t":

h = vt - (1/2)gt²

h = 20t - (1/2)gt²

t = (2h/g - 20)/(-1) (Equation 3)

Now we can substitute Equation 3 into Equation 1 and solve for "h":

h = (1/2)g((2h/g - 20)/(-1))²

h = (1/2)g(2h/g - 20)²

h = (1/2)g(4h²/g² - 80h/g + 400)

Simplifying this equation by multiplying everything by 2g and moving all the terms to one side, we get:

4h² - 160h - 400 = 0

Solving this quadratic equation using the quadratic formula, we get:

h = (160 ± sqrt(160² + 4(4)(400))) / (2(4))

h = (160 ± sqrt(32,000)) / 8

We can ignore the negative solution, so:

h = (160 + 178.88) / 8

The velocity of the other pool ball is (3, -1) m/s.

We can solve this problem using the principle of conservation of momentum, which states that the total momentum of a system remains constant if no external forces act on it.

Let the initial velocity of the stationary pool bar be (0,0) m/s. The initial momentum of the system is:

p_initial = m1 * v1 + m2 * v2

where m1 and m2 are the masses of the pool balls, and v1 and v2 are their initial velocities.

Substituting the given values, we have:

p_initial = 0.1 kg * (5, -4) m/s + 0.1 kg * (0,0) m/s

= (0.5, -0.4) kg m/s

After the collision, the total momentum of the system is still conserved, but now we have one ball at rest and the other moving with a velocity of (2, -3) m/s. Let the velocity of the other pool ball be (vx, vy) m/s. Then we have:

p_final = m1 * (2, -3) m/s + m2 * (vx, vy) m/s

where m1 and m2 are still the masses of the pool balls.

Setting the initial and final momenta equal and solving for (vx, vy), we get:

p_initial = p_final

0.5, -0.4 = 0.1 * (2, -3) + 0.1 * (vx, vy)

0.5, -0.4 = (0.2, -0.3) + (0.1vx, 0.1vy)

0.5 - 0.2 = 0.1vx

-0.4 + 0.3 = 0.1vy

vx = 3 m/s

vy = -1 m/s

Therefore, the velocity of the other pool ball is (3, -1) m/s.

The vector A carries you 222.487 units to the right, vector B carries you 86.424 units to the left, and vector C carries you 42.324 units to the left in the x-direction

To determine the x-direction component of each vector, we need to use trigonometry. We can use the cosine function to find the x-component of each vector since cosine gives the adjacent side length of a right triangle.

For vector A:

The length of the adjacent side (x-component) is given by: cos(15°) = 0.9659

The x-component of vector A is therefore: 230 x 0.9659 = 222.487

For vector B:

The length of the adjacent side (x-component) is given by: cos(237°) = -0.7252 (since cosine is negative in the second and third quadrants)

The x-component of vector B is therefore: 120 x -0.7252 = -86.424

For vector C:

The length of the adjacent side (x-component) is given by: cos(188°) = -0.1997 (since cosine is negative in the second and third quadrants)

According to general relativity, Earth goes around the sun rather than flying straight off into space because of the curvature of spacetime caused by the mass of the sun.

The general theory of relativity explains how gravity is actually caused by the curvature of spacetime and not by any actual force at all. The mass of the sun bends spacetime, which in the case of the Earth orbiting the sun causes the Earth to move on a curved orbit. The orbit of the Earth is visible as a curving path.

The Earth would indeed continue to move in a straight line if it weren't for the sun's mass's effect on the curvature of spacetime.

Where F is the electric force, k is Coulomb's constant (8.99 x 10^9 Nm^2/C^2), q1 and q2 are the charges on the objects, and r is the distance between them.

If each object had 0.6 times as much charge, then the new charges would be:

So the answer with two significant figures and appropriate units is Kinetic energy at second point is 3.7 x 10^6 J or 3.7 MJ.

Kinetic energy is a form of energy that an object possesses by virtue of its motion. It is defined as the energy that an object has due to its mass and velocity. The formula shows that the kinetic energy of an object increases as its mass and velocity increase. For example, a heavy truck traveling at a high speed has a higher kinetic energy than a small car traveling at the same speed. The concept of kinetic energy is important in physics, as it is used to explain many phenomena, such as collisions, projectile motion, and the behavior of waves. It is also useful in engineering and other fields, as it helps to quantify the energy required for different types of motion, such as in machines or vehicles.

Here,

According to the law of conservation of energy, the total mechanical energy of a system remains constant if there are no external forces acting on the system. In the case of a satellite in an elliptical orbit around the Earth, the total mechanical energy is the sum of its kinetic energy and gravitational potential energy.

We can use this principle to solve for the kinetic energy of the satellite when its potential energy is 5600 MJ. We know that the total mechanical energy is conserved, so:

Total mechanical energy at first point = Total mechanical energy at second point

(KE + PE)1 = (KE + PE)2

Substituting the given values:

4100 MJ + 5200 MJ = KE2 + 5600 MJ

Simplifying:

KE2 = (4100 MJ + 5200 MJ - 5600 MJ)

KE2 = 3700 MJ

Therefore, the kinetic energy of the satellite at the second point is 3700 MJ. It's important to note that the units for energy are Joules (J), and mega-Joules (MJ) are equal to 1,000,000 Joules.

Answer:

first question= approximately 6.8 cm

second question=approximately 2.88 x 10^-28 N

Explanation:

To determine the separation distance between the charges, we can use Coulomb's law, which states that the force between two point charges is given by:

F = k * q1 * q2 / r^2

where F is the force, k is Coulomb's constant (9 x 10^9 N m^2/C^2), q1 and q2 are the magnitudes of the charges, and r is the separation distance between the charges.

In this case, we have q1 = 5.0 x 10^-6 C, q2 = -6.0 x 10^-6 C, and F = -0.72 N. Plugging in these values and solving for r, we get:

-0.72 N = (9 x 10^9 N m^2/C^2) * (5.0 x 10^-6 C) * (-6.0 x 10^-6 C) / r^2

Solving for r, we get:

r = sqrt[(9 x 10^9 N m^2/C^2) * (5.0 x 10^-6 C) * (-6.0 x 10^-6 C) / (-0.72 N)]

r ≈ 0.068 m or 6.8 cm

Therefore, the separation distance between the charges is approximately 6.8 cm.

For the second question, we can use the same formula, Coulomb's law, to find the force between the charges:

F = k * q1 * q2 / r^2

Plugging in the values, we get:

F = (9 x 10^9 N m^2/C^2) * (1.6 x 10^-19 C) * (3.2 x 10^-19 C) / (0.02 m)^2

F ≈ 2.88 x 10^-28 N

Therefore, the force between the charges is approximately 2.88 x 10^-28 N.
