The correct answer is (B)
Which is (kQ1Q2) / d^2
Answer:
The entire cart/hanging mass system follows the same law, ΣF = ma. This means that plotting force vs. acceleration yields a linear relationship (of the form y = mx).
you can increase kinetic thermal energy of the water by boiling it.
Answer:30.08 ms
Explanation:
Given
time Constant 
Also rate at which energy is dissipated in the resistor equal to the rate at which energy is stored in inductor's magnetic Field
Energy stored in Inductor is 
rate of Energy storing 
Rate of Energy dissipation from resistor i.e. Power is given by

Equating 1 and 2


i is given by 

substitute the value of
in 3







The kinetic molecular theory of matter offers a description of the microscopic properties of atoms (or molecules) and their interactions, leading to observable macroscopic properties (such as pressure, volume, temperature). An application of the theory is that it helps to explain why matter exists in different phases (solid, liquid, and gas) and how matter can change from one phase to the next.
