Answer:
17.71N/m
Explanation:
The period of the spring is expressed according to the expression;

m is the mass of the object
k is the force constant
Given
m = 5.50kg
T = 3.50s
Substitute into the formula;

Hence the force constant of the spring is 17.71N/m
Answer:
Differences are listed below:
Explanation:
Weight: Plastic can weigh appreciably much less than than metal.A plastic part weighs approximately one-sixth of the same part in steel.
Chemical resistance:Plastic are much less likely to suffer chemical attack and don not corrode.
Machinability: Plastic are much more easier to cut through than metal.
Product life: The life span for plastic is longer than of the metals in many applications.
Cost: The cost of plastic raw materials is appreciably less than of the metals.
Heat: Plastic are less heat resistive than metals.
Ultraviolet light can degrade the plastics soon.
Strength: Metal provides more strength than the plastic.

Determine the linear equation for P in terms of h
First, we calculate the slope/rate (m);
The following formula is used:

Substitute values for P's and h's



Multiply by 1000/1000


The equation is then calculated using:

Substitute values for m, h1 and P1



Make P the subject

<em>The above is the required linear equation</em>
