Answer:

The amount of work done by a crane in lifting a 10,000 kg car is estimated to be 3MJ. This means that the car was lifted to a height of 3,000m. It is important to note that this is an approximate value as the actual height could be different due to factors such as air resistance and efficiency of the crane.

Explanation:

The amount of work done by a crane in lifting a 10,000 kg car is estimated to be 3MJ. To determine the height to which the car was lifted, we need to use the equation of work done (W) which is equal to the force applied (F) multiplied by the distance moved (d). Work done here is equal to 3MJ, force applied is equal to the mass of the car (10,000 kg) multiplied by the gravitational acceleration (10m/s2). Therefore, the equation to determine the distance moved (d) is:

W = Fd

3MJ = (10,000kg)(10m/s2)d

d = 3MJ/(10,000kg)(10m/s2)

d = 3,000m

This means that the car was lifted to a height of 3,000m. It is important to note that this is an approximate value as the actual height could be slightly different due to various factors such as air resistance and the efficiency of the crane.

To understand how this calculation was made, it is important to understand the concept of work. Work is defined as the product of force and the distance moved in the direction of the force. In this case, the force is the gravitational force acting on the car which is equal to the mass of the car multiplied by the gravitational acceleration (10m/s2). The distance moved is in the direction of the gravitational force which is upwards.

The next step is to calculate the work done by the crane in lifting the car. Work done is equal to the force applied multiplied by the distance moved. Here, the force applied is the mass of the car (10,000 kg) multiplied by gravitational acceleration (10m/s2) and the distance moved is the height to which the car was lifted. From the equation of work done, we can calculate the distance moved (d) which is equal to the work done (3MJ) divided by the force applied (10,000kg)(10m/s2). This gives us a value of 3,000m for the distance moved, which is the height to which the car was lifted.

In conclusion, the amount of work done by a crane in lifting a 10,000 kg car is estimated to be 3MJ. This means that the car was lifted to a height of 3,000m. It is important to note that this is an approximate value as the actual height could be slightly different due to various factors such as air resistance and the efficiency of the crane.

The height of the car is lifted is 3,000m.

Work done by a force is defined as the product of the displacement and the component of the applied force on the object in the direction of displacement. When we push a block with some force, the body moves with some acceleration, work is done.

Work done can be calculated with this equation:

Work = Force x Distance.

The SI unit for work is the Newton meter (N m).

The amount of work done by a crane in lifting a 10,000 kg car is estimated to be 3MJ. To determine the height to which the car was raised, we need to use the equation for work done (W), which is equal to the force applied (F) multiplied by the distance moved (d). Here the work done is equal to 3MJ, the force applied is equal to the mass of the car (10,000 kg) multiplied by the acceleration due to gravity is [tex]10m/s^2[/tex]

W = Fd

3MJ = (10,000)(10)d

d = 3/(10,000)(10)

d = 3,000m

Thus, the height of the car is lifted is 3,000m.

The initial energy was lost in collision of a 2350 kg shark moves upward toward a 195 kg fish that is at rest and swallows it whole = 95.33 Joules.

Perfectly inelastic collisions, in contrast to elastic collisions, conserve momentum but not energy. The kinetic energy carried by the moving objects is not always conserved, even though the system's overall energy is always constant. Energy lost to the environment and converted into other forms, such heat, during an inelastic collision.

To determine the energy lost in collision, use the equation:

E = ½ (m1m2) / (m1 + m2) x v²

Where:

m 1 = mass of the object 1

m 2 = mass of the object 2

v 1 = velocity /speed of the object 1

v 2 = velocity / speed of the object 2

v 1 = v2

The speed of light is approximately 3 x 10^8 m/s, we can use this value to find the wavelength.

λ = c/f

λ = (3 x 10^8 m/s) / (6 x 10^17 Hz)

λ = 0.05 nm

So the wavelength of the light beam is 0.05 nm.

The momentum of one of the balls before the collision is 4.5 kg*m/s. The principle of conservation of momentum states that in an isolated system, the total momentum before a collision is equal to the total momentum after the collision.

If two objects are moving toward each other, then their relative velocity is twice the velocity of one object. Given that the total mass of the two bowling balls is 3 kg and the velocity of one of the balls before the collision is 3 m/s, we can use the equation of momentum p=mv to find the momentum of one of the balls.

p = mv

The momentum of one of the balls before the collision is p1 = m1*v1, where m1 is the mass of one of the balls and v1 is the velocity of one of the balls before the collision.

Given that the mass of one of the balls is 3 kg/2 = 1.5 kg.
