Efficiency = (output power) / (input power)
= (3,760 joule/sec) / (4,000 joule/sec)
= 3,760 / 4,000 = 0.94 = 94%
F = G m1*m2 / r^2 => [G] = [F]*[r]^2 /([m1]*[m2]) = N * m^2 / kg^2
That is one answer.
Also, you can use the fact that N = kg*m/s^2
[G] = kg * m / s^2 * m^2 / kg^2 = m^3 /(s^2 * kg)

Answer:
d = 100.56 m
Explanation:
It is given that,
Force acting on the dog is 22.4 N
Angle at which the force is applied is 115 º
Work done is - 42.3 J
We need to find the distance covered by the dog. The work done by an object is given by :
d = distance covered by the dog
So, the dog moves a distance of 100.56 m.
