Energy
How does adding a resistor in series with another resistor affect the equivalent capacitance of a capacitor that's also part of this single-loop circuit?
It doubles the equivalent capacitance of the capacitor.
It increases the equivalent capacitance of the capacitor.
It does not change the equivalent capacitance of the capacitor.
It decreases the equivalent capacitance of the capacitor.
What instrument is commonly used to measure the force applied to an object in a physics experiment?
A voltmeter.
A barometer.
A spring scale.
An ammeter.
In a closed system where two objects collide elastically, which statement best describes kinetic energy distribution after collision?
All kinetic energy transfers to object with greater mass.
Kinetic energy of individual objects increases regardless of mass differences.
Kinetic energy vanishes since momentum is conserved instead.
Total kinetic energy is conserved and shared among objects after collision.
When a sealed syringe is heated and its plunger expands outward without any external forces applied, what concept best describes this phenomenon?
Bernoulli’s Equation involving fluid flow speed relates not to thermal expansion but rather dynamics of moving fluids.
Archimedes’ Principle predicting fluid displacement causes cannot be applied here since no buoyant force acts on gases inside a syringe.
Boyle’s Law describing inverse relationship between pressure and volume at constant temperature applies here.
Gay-Lussac’s Law relating pressure and temperature at constant volume leads to expansion.
Which term best describes the quantity of matter in an object?
Density
Weight
Volume
Mass
What is the difference between a 60W light bulb and a 120W light bulb?
The 120W light bulb can transfer twice as much energy as the 60W light bulb in the same time.
none of the above
There is no real difference between the two light bulbs.
The 120W light bulb loses more energy as heat than the 60W light bulb in the same time.
In an adiabatic process where a gas is compressed, which principle explains the rise in temperature of the gas?
Conservation of Energy
Law of Thermodynamics
Pascal's Principle
Charles's Law

What does Newton’s first law state about objects at rest?
They always contain potential energy which could set them into motion spontaneously.
They will eventually move due to natural entropy increase.
They remain at rest unless acted upon by an unbalanced external force.
They are experiencing balanced forces but can start moving from internal forces alone.
What instrument would you use to find out how long it takes a pendulum to complete one swing?
Calipers.
Spectrophotometer.
Micrometer.
Stopwatch.
In a closed system where no external forces act, what happens to the total momentum?
It decreases over time.
It fluctuates randomly.
It increases over time.
It remains constant.
