Answer:
Work done is 12.3 J
Explanation:
We have,
Mass of puck, m = 0.35 kg
Force of friction acting on the puck when it slides is 0.15 N
Distance travelled by the puck is 82 m.
It is required to find the work done on the puck. Finally the puck comes to rest and the force of friction is acting on it. It means the applied force is 0.15 N. Work done is given by
The work done on the puck is 12.3 J.
The formula for final velocity is Speed= distance/time (s=d/t)
Velocity is another word for speed.
<span>Each laid 250 bricks but while Jake was still working, Josh was lounging in the shade. Josh has more power but that power was only on for 3 hours out of 4.5. Obviously Josh could get more done is less time as long as he keeps working. Jake will get the hang of it soon.</span>
A solar panel are most efficient under natural sunlight, however, a solar panel can work using artificial light simply because a solar panel collects photons which collide with silicon atoms transferring their energy which cause them to lose electrons.
the Republic of South Africa country is being described by these statements
<u>Explanation:</u>
South Africa has the highest amount of people living with HIV/AIDS in the world. It was initially identified in 1982. The ANC came to power in 1994 after ten years of National Party inaction concerning AIDS. The ANC although took province with a formidable strategy, on record at least, for speaking HIV/AIDS.
