Problem 3.(adsbygoogle = window.adsbygoogle || []).push({});

A 127 N object vibrates with a period of 3.45 s when hanging from a spring.

The acceleration of gravity is 9.81 m/s^2.

What is the spring constant of the spring?

Answer in N/m.

Note: How would one solve this type of problem?

Problem 8.

What is its frequendy? In Hz.

Note: WHat formula do I use?

Problem 13.

A paino emits frequencies that range from a low of about 28 Hz to a high of about 4200 Hz.

Find the maximum wavelength in air attained by this instrument when the speed of sound in air is 344m/s. In m.

Note: WHat formula do I use?

Problem 21.

Microwaves travel at the speed of light, 3*10^8m/s.
