Answer:
Electromagnetic waves can travel through empty space.
Explanation:
Electromagnetic waves are defined as the waves that are created due to the vibrations between a magnetic field and an electric field.
Earth atmosphere is made up of several gases and spaces between them. Thermal energy from the sun require to pass through space by electromagnetic radiation. Electromagnetic waves can travel through empty space and that is why other type of waves are unable to transfer thermal energy.
Hence, the correct answer is "Electromagnetic waves can travel through empty space".
The pressure of a liquid on the surface of its container or on the surface of any body in the liquid is equal to the weight of a column of the liquid whose height equals the depth of the liquid at that certain point.
as it is given that curved marked the speed as v = 70 km/h
so we will first convert the speed into m/s
now we know that here friction force will provide centripetal force
As we know that centripetal force is given as
Answer:
Explanation:
Centripetal force acts towards the center of the circle. However, our body is not attached to the car, it is only kept in the car. Therefore, when an external force acts on the car, inertia acts on the body due to the sense that it will try to remain in the same state.
Although the car takes the turn, but due to the inertia, the body will try to move forward; but since the seat belts are on, it is enforced to move with the car in a circular motion
