Answer:
0
Explanation:
Weight = mass x gravity
if gravity = 0 then Weight =0 as well
Answer:
D
Explanation:
When something that needs power that you are turning off you will not need power when its off.
No friction present means: Ek = Ep
So Ek = mgh = 10 * 9.8 * 2 = 196 J
Temperature is just a measure of how HOT or COLD a substance is, which can be easily defined by a magnitude using a numerical value say “300 K” or “27°C”. Hence we can say it is a scalar quantity.
But the energy which transfer by virtue of a temperature difference is a vector quantity, as it has both magnitude and direction of motion (from High temperature to low temperature region).
