Which of the following is an environmental consequence of nuclear energy?

What is the three laws of electrostatics?

dangina [55]

The force exerted between 2 point charges is directly proportional to the product of their strengths, is inversely proportional to the square of the distance between them and is inversely proportional to the absolute permittivity of the surrounding mediums.

I hope that helps somewhat, I'm only kind of sure that could be correct

A tennis racquet swung with an angular velocity of 12 rad/s strikes a motionless ball at a distance of 0.5 m from the axis of ro

Anestetic [448]

Answer:

The linear velocity of the racquet at the point of contact with the ball is 6 m/s.

Explanation:

Given;

angular velocity of the racquet, ω = 12 rad/s

distance of strike, r = 0.5 m

The linear velocity of the racquet at the point of contact is given by;

V = ωr

V = (12)(0.5)

V = 6 m/s

Therefore, linear velocity of the racquet at the point of contact with the ball is 6 m/s.

The humber bridge in england has the world's longest single span, 1410 m . calculate the change in length of the steel deck of t

Pepsi [2]

Applicable linear expansion equation:
ΔL = αΔTL
In which
ΔL = change in length, α = Linear expansion coefficient of steel, ΔT = change in temperature, L = original length

Therefore,
ΔL = 12*10^-6*(18.5-(-3))*1410 = 0.36378 m
