PHY101 Quiz 5 by Iqra Azhar

What happens to the total capacitance when capacitors are connected in series?

It decreases It becomes infinite It remains the same It increases

How does increasing the intensity of light in the photoelectric effect influence the number of ejected electrons?

Decreases the kinetic energy of the photoelectrons. Changes the color of the emitted light. No effect on the number of photoelectrons. Increases the number of photoelectrons.

The primary purpose of the equation of state in thermodynamics is: To define the system's internal energy To relate thermodynamic variables like P, V, and T To explain the conservation of energy To determine the path variables

Which of the following electromagnetic radiations has photons with the greatest momentum?

x rays yellow light blue light

If the source temperature is raised, the efficiency of heat engine will: Remain constant First increase then decrease Decrease Increase

Which of the following types of electromagnetic radiation travels at the greatest speed in vacuum? X rays

Gamma rays All of these travel at the same speed

In relativistic mechanics, the rest energy \[E_0\] is equal to: \[{E_0} = \sqrt {\gamma {m_0}{c^2}}\] E0} = m_0c^2 \[{E_0} = \frac{1}{2}{m_0}{u^2}\] \[{E_0} = \sqrt {{m_0}{c^2}}\]
