Electric motors require electricity to move the motor parts and do work (like an electric fan).
Elecgric generators actually burn diesel fuel to spin a motor around and around and around to GENERATE, or MAKE, electricity that you can then use to power your fans and lights in your house.
Answer:
Static stretching.
Explanation:
It is static stretching because it is a form of stretching which u can do actively for a period of time and you hold position for about 30 to 60 seconds which allow the muscles and connective tissues to lengthen. It is done after work out with out movement in order to loosen up muscles so as to gain flexibility.
Momentum is the product of mass and velocity of a body. In this case, the bus has a mass of 18200 kg and moving with a velocity of 10 m/s.
Therefore, the momentum of the bus will be, 18200×10 = 182,000 kgm/s.
Thus a ball of mass 0.142 kg will require to travel with a speed of;
= 182000/0.142
= 1.282 ×10∧6 m/s to have the same momentum with the bus.
