Science Challenge: Motion and Sound

What is the formula for calculating force according to Newton's second law?

• F = m * a

• F = m + a

• F = m - a

• F = m / a

How many laws of motion did Newton formulate?

• 3

• 4

• 5

• 2

What is the unit of measurement for force in the International System of Units (SI)?

• pascal (Pa)

• newton (N)

• watt (W)

• joule (J)

What type of wave is a sound wave: longitudinal or transverse?

• longitudinal

• transverse

• circular

• electromagnetic

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

• 250 m/s

• 343 m/s

• 400 m/s

• 300 m/s

What is the frequency range of human hearing in Hertz (Hz)?

• 10 Hz to 15,000 Hz

• 50 Hz to 25,000 Hz

• 20 Hz to 20,000 Hz

• 5 Hz to 30,000 Hz

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

• Wavelength is inversely proportional to frequency in sound waves.

• Wavelength is directly proportional to frequency in sound waves.

• Wavelength increases as frequency increases in sound waves.

• Wavelength and frequency are unrelated in sound waves.

What is the universal law of gravitation formula?

• F = G * (m1 * m2) / r^2

• F = m1 * m2 / G * r^2

• F = G * m1 * m2 * r^2

• F = G * (m1 + m2) / r

If the mass of an object is doubled, how does the gravitational force change?

• The gravitational force remains the same.

• The gravitational force quadruples.

• The gravitational force decreases by half.

• The gravitational force doubles.
