C and D are likewise incorrect as primary sources are important, and you can share the results with others if you want to.
Thermal equilibrium is a state in which all parts of a system are at the same temperature
Explanation:
because as you can see beaker 2 has higher temperature. As volume is directly propotional

more energy so that's why levels are different.
Answer:
F = M a = M v^2 / R
If v is increased by three the force will be increased by nine,
C) is correct
