Weight = Mass times Acceleration due to gravity.
Weight = 10 kg times 9.8 m/s^2
Weight = 98 kg

Answer:
for a cell to produce a current the cell electrodes of the cell must have a potential difference option A is the correct answer
Answer:
v=2.42m/s
Explanation:
We use the energy conservation theorem in order to solve the problem. The energy when the spring is compressed is equal at the energy when the disk leaves the spring:

At the beginning the initial energy is totally potential, energy linked to the compressed spring. At the end the energy is totally kinetics
We solve the equation in order to find the speed.
k=162 N/m
x=7 cm=0.07m
m=0.135 kg

Answer: I think I have the answer to your problem!!
A pot of boiling water is a nice everyday example to explain internal energy, heat, and work. However, it's not a good choice for applying the first law of thermodynamics, because the boiling pot isn't a closed system.
