Because of the power of the light it is very strong so that is why light reaches all the way to earth
If the climber is not accelerating then a=0. Then F=ma=0. This is because the upward force of the rope is equal and opposite to the force due to gravity. So the net (total) force is 0
Answer:
The transmission of energy is one thing that is carried out by all kinds of waves. They transmit energy from one point, known as the source, to another point.
For instance, in electromagnetic waves, energy is transmitted as a result of vibrations between the magnetic field and electric field. In mechanical waves, energy is transmitted when the particles in the medium heat up and vibrate. Energy travels through particles in a medium.
Because the people in the car are attached to the vehicle, the people inside the vehicle are going the same speed as the vehicle.
Hope this helps! :)
Answer:
The thrust of the jet engine is 4188.81 N.
Explanation:
Given that,
Speed = 260 m/s
Rate in air= 53.3 kg/s
Rate of fuel = 3.63 kg/s
Relative speed = 317 m/s
We need to calculate the rate of mass change in the rocket
Using formula of rate of mass
Put the value into the formula
We need to calculate the thrust of the jet engine
Using formula of thrust
Put the value into the formula
Hence, The thrust of the jet engine is 4188.81 N.
