Front

What happens to frequency if the wavelength increases while wave speed is constant?

Back

The frequency will decrease.

Front

Which car is considered to be accelerating?

Back

A car that rounds a curve at a constant speed.

Front

What does a graph showing no change in position over time represent?

Back

Not moving.

Front

Calculate the heat needed to raise the temperature of 0.25 kg of aluminum by 7°C (c=900 J/kg°C).

Back

1575 J.

Front

Temperature is proportional to what?

Back

The average kinetic energy of the particles of a substance.

Front

Define wave speed.

Back

Wave speed is the distance traveled by a wave per unit time.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object.

Front

What is the formula for calculating heat transfer?

Back

Q = mcΔT, where Q is heat, m is mass, c is specific heat, and ΔT is the change in temperature.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object due to its motion.

Front

What is the relationship between temperature and kinetic energy?

Back

Temperature is a measure of the average kinetic energy of the particles in a substance.
