Front

An example of a longitudinal wave is a ____

Back

Sound wave.

Front

If the angle of incidence is 45 degrees, what is the angle between the incident ray and the reflecting surface?

Back

45 degrees.

Front

An object's resistivity to changes in its motion is defined as:

Back

Inertia.

Front

What is the definition of electric current?

Back

Electric current is the flow of electric charge, typically measured in amperes.

Front

What is Ohm's Law?

Back

Ohm's Law states that the current through a conductor between two points is directly proportional to the voltage across the two points.

Front

What is the formula for calculating kinetic energy?

Back

Kinetic energy (KE) = 1/2 mv², where m is mass and v is velocity.

Front

What is the principle of conservation of energy?

Back

The principle states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.
