Answer:
Explanation:
mechanical advantage = output force / input force
= 740 N / 55 N
= 13.45
I think the answer would be : A. more powerful
The shorter the electromagnetic wave is, the closer it is to the electromagnetic core, which make it more powerful
hope this helps
-- A motor and a generator both do a transformation between electrical energy and some other form of energy, but they do it in opposite directions.
-- A motor takes electrical energy and transforms it into mechanical energy, which can then be used to run mechanical things like cars or wheat grinders.
-- A generator takes mechanical energy ... like from a steam turbine or a windmill or a water wheel ... and transforms it into electrical energy, which can then be shipped over long distances through wires, and used to run motors or other electrical things.
Answer:
Light travels at a constant, finite speed of 186,000 mi/sec.

Light travels at a constant, finite speed of 186,000 mi/sec.
Answer:
6. W = 3 m g h
Explanation:
Displacement in moving from first floor to the fourth floor is 3h, and the total energy consumed in this process is (3.m.g.h) which is equal to the work done.
According to the work-energy equivalence the change in energy of a system is equal to the work done.
Here, change in potential energy:
