Answer:
Your mobile charger is an example of (d.) a generator.
Explanation:
Your mobile charger generates energy to charge your device.
Answer:
d = 5.10 m
Explanation:
As we know that here on the plane of the inclined there is no frictional force
So in these cases we can say that total mechanical energy will always remains conserved
so here we can say that
spring potential energy = gravitational potential energy of the block
as we know from the formula

now plug in the values in it



now as we know that the angle of inclination is 60 degree and height raised is 4.42 m
so here maximum distance moved along the inclined plane will be



Answer:
a) Volt
Explanation:
The standard metric unit on electric potential difference is the volt.
Potential energy relative to the floor =
(mass) x (gravity) x (height off the floor) =
(2kg) x (9.8 m/s²) x (2m) =
39.2 kg-m²/sec² = <em>39.2 joules </em>
