Question

A 120g copper ball is placed on a 5g copper spring in a sealed insulated container. The spring (with k=200 J/m^2) is initially stretched 15cm longer than its free resting position.

a) True
b) False

Answer 1

The questions cover Hooke's law and simple harmonic motion, requiring calculations of spring force constants, spring displacement, and energy stored in springs. The statement is false

Step-by-step explanation:

The questions relate to the physical concept of Hooke's law, which defines the relationship between the force needed to compress or extend a spring and the distance the spring is stretched or compressed. Questions also touch on simple harmonic motion (SHM), potential energy stored in springs, and the physical properties of a copper wire in a circuit. Specifically, the questions request calculations of spring constants, displacement, total energy in the system, and potential energy in various scenarios where springs are involved. The statement is false
