What is the power consumed across AB?

The missing part of the question have been filled below on Continental drift

In the early part of the 20th century, a German scientist named Alfred Wegener, proposed the theory of continental drift which suggested the continents move and started out in different positions from what they are currently. In the 1960s, scientists discovered the spreading apart of areas of the sea floor. This in turn led to the theory of plate tectonics. The lithosphere is made of plates which float on a "plastic-like" undersurface called the mantle. Where these plates come together at boundaries, changes take place in the crust and its feature.

The turbine generates approximately 781.78 kW of power in a 14 m/s wind.

The power generated by a wind turbine is directly proportional to the cube of the wind speed. Therefore, we can write:

p ∝ [tex]v^3[/tex]

where "p" is the power generated in kilowatts (kW) and "v" is the wind speed in meters per second (m/s). We can also introduce a constant of proportionality "k" to get:

p = k [tex]v^3[/tex]

To find the value of "k", we can use the given information that the turbine generates 600 kW in a 13 m/s wind. Thus:

600 = k x [tex]13^3[/tex]

Solving for "k", we get:

k = 600 / [tex]13^3[/tex]

k = 0.270270...

Now we can use this value of "k" to find the power generated by the turbine in a 14 m/s wind. Thus:

p = 0.270270... x [tex]14^3[/tex]

p ≈ 781.78 kW

Therefore, the turbine generates approximately 781.78 kW of power in a 14 m/s wind.

At a height of 4.48 meters, a rock's kinetic energy is twice its potential energy.

Potential energy is the energy stored in any object or system due to the position or arrangement of its parts. It is, however, unaffected by factors outside of the object or system, such as air or height. Kinetic energy, on the other hand, is the energy of moving particles in an object or system.

Given that a 6.0-kg rock is dropped from a height of 9.0 m.

Calculate the total potential energy at the initial point,

PE = mgh

PE = 6 x 9.81 x 9

PE = 530.74 J

At the zero height, the kinetic energy will be maximum and is equal to the total energy,

KE = 530.75 J

1/2 mv² = 530.75

v² = 175.85

The height at which the kinetic energy is two times the potential energy is calculated as:-

1 /2 x mv² = 2 x mgh

h = ( 4 v²) / ( 4 x 9.81 )

The density of the object is:

rho object = m / V = 300 / 720 = [tex]0.4167 kg/m^3[/tex]

When an object is immersed in liquid, it appears to lose weight equal to the weight of the liquid displaced. Apparent weight loss is caused by an upwardly acting buoyant force that balances the weight of the object.

This problem can be solved using Archimedes' principle that the buoyant force on an object is equal to the weight of the liquid displaced by the object.

First, let's calculate the volume of the object. An object in air weighs 300 N. When immersed in water, the weight is reduced to 262 N. This means that the buoyant force acting on the object is 300 - 262 = 38 N.

Buoyancy is equal to the weight of water displaced by an object. Therefore, the volume of the object is:

[tex]V = m\ water / rho\ water = F\ buoyant / g / rho\ water[/tex]

where m water is the mass of water displaced by the object, rho water is the density of the water, F buoyancy is the buoyant force acting on the object, and g is the acceleration is respect of gravity.

Inserting the given value will result in:

[tex]V = 38 / 9.81 / 1000 = 0.00387 m^3[/tex]

Now let's calculate the density of an object when submerged in oil.

The object immersed in oil weighs 273 N. The buoyant force acting is:

F buoyancy = 300 - 273 = 27 N

The buoyant force is same to the weight of oil displaced by the object. So the volume of the object is:

V = m oil / rho oil = F buoyant / g / rho oil

where m oil is the mass of oil displaced by the object, rho oil is the density of the oil, F is the buoyant force acting on the object, and g is the acceleration due to gravity.

Inserting the given value will result in:

V = 27 / 9.81 / rho oil

We know that the volume of this object is 0.00387 [tex]m^3[/tex]. After inserting this value:

0.00387 = 27 / 9.81 / low oil

Solving Rho Oil gives:

Rho oil = 720 kg/

Answer:

Below

Explanation:

Total mass = ( 50 + 7 + 4)  = 61 kg

    momentum = m * v

                        = 61 kg * 3 m/s = 183 kg m/s

Answer:

The change in momentum of an object is equal to the impulse applied to it. Impulse is the product of force and time, or J = FΔt.

In this case, the force acting on the rocket is 500 N, and the time it is applied is 600 s, so the impulse is:

J = FΔt = (500 N) * (600 s) = 300000 Ns

The impulse applied to the rocket causes a change in momentum, which is given by the formula:

Δp = J

So the change in momentum of the rocket is 300000 Ns.

The resultant force that water exerts on the overhang sea wall along abc is 179 kN.

Force is a physical quantity that describes the interaction between two objects, such as a push or a pull. It is defined as any influence that causes an object to undergo a change in motion or deformation. Force is a vector quantity, meaning that it has both magnitude (size or strength) and direction.

Component that is horizontal. Because AB is horizontal, there is no horizontal component. The horizontal component of BC's force is.

(Fbc)h =γwhˉA=(1000kg/m3)(9.81m/s2)(1.5m+21(2m))(2m(2m))=98.1(103)N.

Component that is vertical. The weight of the water contained in blocks Abefa and Bcdeb (shown shaded in Fig. a) is equal to the force on AB and the vertical component of the force on BC. Here,

Aabefa=1.5m(2.5m)=3.75m2and

2Abcdeb=(3.5m)(2m)–4π(2m)2=(7–p)m2. Then,

Fab=γwVabefa=(1000kg/m3)(9.81m/s2)[(3.75m2)(2m)] =73.575(103)N=73.6N (FBC)v=γwVbcdeb=(1000kg/m3)(9.81m/s2)[(7–π)m2(2m)] =75.702(103)N

Therefore,

The net electric potential at the origin due to the circular arc of charge Q1, and the two particles of charges Q2 and Q3 can be calculated by using the formula for electric potential due to a point charge:

V = (kQ)/r

Where V is the electric potential, k is the Coulomb's constant (8.99 x 10^9 Nm^2/C^2), Q is the charge, and r is the distance from the point of charge to the point where we want to calculate the electric potential.

For the circular arc of charge Q1, the electric potential at the origin is:

V1 = (kQ1)/R = (8.99 x 10^9 Nm^2/C^2)(7.21 x 10^-12 C)/(2.00 m) = 1.62 x 10^-2 V

For the particle of charge Q2, the electric potential at the origin is:

V2 = (kQ2)/R = (8.99 x 10^9 Nm^2/C^2)(4.00Q1)/(2.00 m) = 4.00V1 = 6.48 x 10^-2 V

For the particle of charge Q3, the electric potential at the origin is:

V3 = (kQ3)/R = (8.99 x 10^9 Nm^2/C^2)(-2.00Q1)/(2.00 m) = -2.00V1 = -3.24 x 10^-2 V

The net electric potential at the origin is the sum of the electric potentials due to each charge:

Vnet = V1 + V2 + V3 = 1.62 x 10^-2  V  + 6.48 x 10^-2  V  - 3.24 x 10^-2  V

Vnet = 4.86 x 10^-2 V

Therefore, the net electric potential at the origin due to the circular arc of charge Q1 and the two particles of charges Q2 and Q3 is 4.86 x 10^-2 V.

The spaceship undergoes an instantaneous change in velocity at point A and then undergoes a continuous change in velocity at point B until it reaches point C. The trajectory of the spaceship is therefore curved and can be represented by one of the given options.

What is Instantaneous Velocity?

Instantaneous velocity is the velocity of an object at a specific moment in time or at a specific point in its motion. It is the limit of the average velocity as the time interval over which it is calculated approaches zero. In other words, it is the slope of the tangent to the position-time graph at a particular point.

To calculate the instantaneous velocity of an object, you need to determine the object's position at a specific moment in time and then take the derivative of the position function with respect to time. The resulting derivative gives you the object's instantaneous velocity at that specific moment in time.

Instantaneous velocity is important in physics and many other fields because it allows us to understand the behavior of objects in motion and to calculate important quantities such as acceleration, momentum, and energy.

The gravitational force pulls any two things in the cosmos, regardless of whether their masses are equal or not.

The weight of an object depends on its mass and the gravitational force acting on it. Therefore, if two objects have different weights, it does not necessarily mean that one object has a greater volume or weight density than the other.

For example, object A could be made of a denser material than object B, even though it weighs more, so it would occupy less volume. Similarly, object A could have a lower volume but a greater weight density than object B. Specific gravity also depends on the density of the object and the density of the reference material, so it cannot be determined without additional information.
