When a 19 N force is applied, it compresses a spring by 0.085 m. Determine the period of oscillation of a 4.0-kg object making a simple harmonic motion with this spring.

A mass of a sculpture made of lead is initially 5 kg. What would be the increase in the mass of the sculpture when its temperature is increased by 525 C°. The specific heat capacity of lead is 128 J/(kg x C°).    

Muons are cosmic particles generated in the upper part of the atmosphere. Their mean lifetime, in the reference frame of the muon, is 2.2 × 10–6 s. Now, assume a muon travelling with a speed of 0.6c relative to an observer on Earth. What would be the approximate distance this muon travels, according to the observer?

An instructor is showing the standing waves demo in the class. A 4.00-m long string, clamped at both ends, vibrates with a frequency of 200 Hz. On the string, the students can clearly see a standing wave with six segments. What is the speed of transverse waves on the string?
