Electric Force, Field, and Potential
What happens to the gravitational potential energy of a satellite in low Earth orbit if its orbital radius is increased without changing its mass or orbital speed?
The gravitational potential energy increases.
The gravitational potential energy decreases.
There isn't enough information to determine a change in gravitational potential energy.
The gravitational potential energy remains unchanged.
In an AC circuit containing only a capacitor, what happens to the current if both the frequency of the source voltage and the capacitance are doubled?
The current decreases by half.
The current increases by four times.
The current remains unchanged.
There is not enough information to determine the change in current.
Which theory explains the fundamental interaction through exchange particles known as gauge bosons?
Theory Of Relativity
Thermodynamics
Classical Mechanics
Quantum Field Theory
If the distance between two charged particles is halved, how does the electric force between them change according to Coulomb's Law?
It halves.
It decreases by a factor of four.
It increases by a factor of four.
It doubles.
What change occurs in a reversible isothermal expansion of an ideal gas within a closed system?
There is no change in either internal energy or work done by the gas.
The internal energy of the gas increases while doing work on its surroundings.
The gas does work on its surroundings while its internal energy remains constant.
The gas absorbs heat without doing any work on its surroundings.
In an isolated system where two objects at different temperatures come into thermal contact, how does energy flow between them?
From the lower-temperature object to the higher-temperature object until thermal equilibrium is reached.
From the higher-temperature object to the lower-temperature object until thermal equilibrium is reached.
Equally from both objects regardless of their initial temperatures.
Energy does not flow in isolated systems.
Why do heavier elements exhibit less pronounced quantum mechanical behavior than lighter ones under normal conditions?
Their larger mass leads to shorter de Broglie wavelengths making quantum effects harder to detect.
Quantum effects are independent of mass, rendering element weight irrelevant.
Heavier elements absorb more energy before showing quantum mechanical behavior.
Lighter elements have lower gravitational attraction affecting their quantum states.
