Front

What is the formula to calculate power?

Back

Power (P) = Work (W) / Time (t) where Work is measured in Joules and Time in seconds.

Front

What is the unit of power?

Back

The unit of power is the Watt (W), which is equivalent to Joules per second (J/s).

Front

If an alligator exerts a bite force of 9,000 N over a distance of 0.5 m in 0.25 seconds, how much work is done?

Back

Work (W) = Force (F) x Distance (d) = 9,000 N x 0.5 m = 4,500 J.

Front

How do you calculate the power of the alligator's bite?

Back

Power (P) = Work (W) / Time (t) = 4,500 J / 0.25 s = 18,000 W.

Front

What is an example of a place where no sound exists?

Back

Space is a place where no sound exists because it is a vacuum.

Front

What is a sound wave?

Back

A sound wave is a type of mechanical wave that propagates through a medium (like air, water, or solids) and is perceived as sound.

Front

What determines the pitch of a sound?

Back

The pitch of a sound is determined by the frequency of the sound wave; higher frequency means higher pitch.

Front

What is the relationship between frequency and wavelength in sound waves?

Back

Frequency (f) and wavelength (λ) are inversely related; as frequency increases, wavelength decreases, and vice versa.

Front

What is the speed of sound in air at room temperature?

Back

The speed of sound in air at room temperature (20°C) is approximately 343 meters per second.

Front

What is a vacuum?

Back

A vacuum is a space devoid of matter, including air, where sound cannot travel.
