3 protons should be your answer
Answer:
lesser time
Explanation:
The latent heat of fusion is defined as the amount of heat required to convert 1 gram of water into 1 gram of ice at constant temperature called melting point.
In this situation only the state of matter is changed, the temperature of the substance remains constant.
A liquid has lower latent heat rather than water, it means it requires lesser amount of heat to fuse it , so it requires lesser amount of time to melt the ice made by this liquid.
So, it requires lesser time.
Answer:
Work done by the little rocket engine = 19.6 Joules.
Explanation:
We know that work = force x displacement.
Force = weight of rocket = 4.9 N
Displacement = 5 meter.
So work done by the little rocket engine = Weight of rocket x displacement.
Work done by the little rocket engine = 4.9 x 4 = 19.6 J
Work done by the little rocket engine = 19.6 Joules.
Answer:
Explanation:
For resistances in parallel we know that the overall resistance will be smaller in the value than any individual resistance. so, in this case we are concerned about 
= 
⁺ 
where Rs is the series resistor and Rp is the parallel resistor.
so, R = 0.9M, roughly.
So, as the infernal resistance is very high as compared to the resistance conntected in parallel that is 100 Ω is not be used.
