The cT is short for continental tropical. It originates over the Mexican Plateau region and desert SW. It is a warm air mass over a continent. It is hot and very dry because of where it formed. Hope these facts about continental tropical air masses helped you!
The spring constant, k will be 18 N/m.The ratio of force to one unit of displaced length is known as the spring constant.
<h3>What is the spring constant?</h3>
Spring constant is defined as the ratio of force per unit displaced length.
Given data;
Mass of block,m=0.250 k
Amplitude,A = 0.125 m
Velocity,V=3.00 m/
Spring constant,K=?
The formula for the spring constant when the spring is oscillate at the given amplitude A:

Hence, the spring constant, k will be 18 N/m
