Answer:
Advantage:
It makes work faster and easier
Disadvantage:
The work to its very best
Explanation:
More people reduces the time spent on one work which makes easier to finish but the work might not be done to its very best because different people are doing the job
Answer:
50ohms
Explanation:
If the power in an electric circuit varies inversely with the resistance, it can expressed as P = k/R where;
P is the power, R is the resistance and k is the constant of proportionality.
From the formula, k = PR
k = P1R1 = P2R2...(1)
Given P1 = 2200watts, R1 = 25ohms, P2 = 1100watts R2 = ?
From equation (1);
R2 = P1R1/P2
R2 = 2200×25/1100
R2 = 50ohms
The resistance when the power is 1100watts is 50ohms.
This shows that as the power is decreasing, the resistance is increasing.
Just gonna grab some points by answering this. Have a good day!
Hooke's law states that the elongation of a material is proportional to the applied stress within the elastic limits of the material.
Using Hooke's law
F = kx
570 = k * 0.9
k = 712.5 N/m
(a) energy at x = 0.8 m
U = 0.5 k x^2 = 0.5* 712.8* 0.8^2
U = 228 J
(b) U = 0.5 * 712.8* 0.09^2
U = 2.887 J
Elastic potential energy is the potential energy released as a result of the deformation of an elastic body. B. Spring extension is stored. This is equal to the work done to stretch the spring, which depends on the spring constant k and the stretched distance. The force exerted by the spring is the restoring force that helps return the spring to its equilibrium length.

The value of v; initial velocity is determined as, v = h/t + gt.
<h3>What is initial velocity of an object?</h3>
The initial velocity of an object is the velocity of the object before the effect of acceleration, which causes the change of velocity.
h = vt - gt²
to solve for v (the initial velocity) we will make v the subject of the formula.
h + gt² = vt
divide both sides of the equation by t
h/t + gt = v
Thus, the value of v; initial velocity is determined as, v = h/t + gt.
