Answer:

The moon orbiting Earth

Explanation:

- The work done is given by:

                            W = integral (F).ds

In words, It is the dot product of Force in the change displacement. In every case the the force is in the direction of displacement.

Except, when the moon is orbiting the earth, the change in displacement is zero. Hence, the work done is zero as ds = 0.

andrew11 [14]

Answer:

x=2d

Explanation:

initial stretch in the spring is d

so using Hook's law

at equilibrium position

k×d=mg

where k= spring constant

m= mass of fish

g= acceleration due to gravity.

d=mg/k ................ (1)

in second case  by energy conservation

1/2 kx^2=mgx

x=2mg/k

using equation 1

x=2d
