Answer:
(Equation 10.3. 2): RS=R1+R2+R3+R4+R5=20Ω+20Ω+20Ω+20Ω+10Ω=90Ω
The kinetic energies of a light and a heavy body are equivalent. The momentum is greater for the light body.
<h3>What is momentum?</h3>
Momentum is characterized as the intensity of a body's motion. As momentum depends on both velocity and the direction of the body's motion, it is quantified by "mass velocity". Since velocity is a vector and mass is a scalar, momentum is a vector quantity.
As a result of its higher mass, a heavy object will move with more momentum. Only when the average speed of the heavy particles is lower than that of the light particles will the average kinetic energy of the light particles equal the average kinetic energy of the heavy particles.
At the same temperature and pressure, lighter gases will move more quickly than heavier ones. 0K on the Kelvin scale denotes that the particles are not moving.

Answer:
B. An isothermal compression of an ideal gas.
Explanation:
The internal energy of an ideal gas is just function of the temperature; it does not matter what other thermodynamic property changes, if the temperature does not change, the internal energy neither does. That is just for ideal gases; real gases behaviour is not like that. All of the other options bring with them an increase or decrease of the temperature:
For A, the temperature will decrease because the gas will do work as it expands, converting part of his internal energy to work.
For C, the temperature will increase, because given 
, if the volume increases (expansion) and the pressure is constant, the temperature must increase to satisfy the equation.
Answer:
See explanation
Explanation:
Since the original count rate is 600 Bq,
i) after 1 half life, the count rate decreases to 1/2 of 600 Bq = 300 Bq
ii) after 2 half lives, the count rate decreases to 1/4 of 600 = 150 Bq
iii) after 3 half lives, the count rate decreases to 1/6 of 600 = 100 Bq
iv) after 4 half lives, the count rate decreases to 1/8 of 600 = 75 Bq
