Answer:

Spring constant, K = 415.9 N/m

Explanation:

The period of vibration of a spring, T, is given by:

T = 2√m/K

Where m = mass of the body in kg, K = spring constant or force constant or elastic constant or stiffness in Nm-1

Making K the subject of the expression,

K = m(2)2/(T)2

K = 4m()2/(T)2

Where m = 0.38kg, = 3.14285714286, T = 0.19s

K = 4 x 0.38 (3.14285714286)2 / (0.19)2

K = 4 x 0.38 x 9.87755102043 / 0.0361

K = 15.0138775511 / 0.0361

K = 415.9 Nm-1

Airida [17]

This question is incomplete because the options are missing. Here are the options.

A. Bullying

B. Workplace Harassment

C. The MUM effect

D. A hostile work environment

Telitha notices that a coworker always undercharges her friends when they make purchases at the shop. Telitha is worried that if she reports this coworker, everyone will think she's a snitch. This is an example of the MUM effect.

The MUM Effect (Minimizing Unpleasant Message) is a term to refer to the human tendency to avoid or hide the communication of negative information or unpleasant news. This trend is because people believe that communicating negative information will affect their public image. In addition, they are emotionally affected.

Therefore, Telitha is concerned about reporting to her partner because this can affect her social image, and she can be seen as a snitch. So the answer is C.

Also, this is not an example of hostility, bullying or harassment because this worker is not being attacked by others.
