Problem 3.
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.
A spring with a spring constant of 28.9 N/m is attached to different masses, and the system is set into motion.
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.
When the frequency of microwaves is 7.35*10^9 Hz, what is their wavelength? In m.
