A device that changes mechanical energy to electrical energy by rotatin a coil of wire through a magnetic field is called B. Generator
Answer:
567m
Explanation:
By using formula of velocity.
Answer:
Mechanical advantage = 2.875
Explanation:
Given:
A diagram is shown below for the above scenario.
Length of ramp (Effort arm) = 4.6 m
Height of truck bed ( Resistance length) = 1.6 m
Mechanical advantage (MA) is the ratio of effort arm and resistance length.
So, mechanical advantage is given as,

The gravitational force is inversely proportional to the
square of the distance between their centers. So the
force is greatest when the distance is zero.
