Answer:

1.11 x 10^6 m

Explanation:

mass of Pluto, M = 1.1 x 10^22 kg

acceleration due to gravity on Pluto, g = 0.59 m/s²

let R be the radius of the Pluto and G is the universal gravitational constant.

G = 6.67 x 10^-11 Nm²/kg²

use the formula for the acceleration due to gravity

g = \frac{GM}{R^{2}}

R = \sqrt{\frac{GM}{g}}

R = \sqrt{\frac{6.67\times10^{-11}\times 1.1\times 10^{22}}{0.59}}

R = 1.11 x 10^6 m

Thus, the radius of the Pluto is 1.11 x 10^6 m.

Why can’t a real machine ever have 100% efficiency
Harman [31]

Answer:

Almost all machines require energy to offset the effects of gravity, friction, and air/wind resistance. Thus, no machine can continually operate at 100 percent efficiency.

A man does 500 J of work pushing a car a distance of 2 m. How much force does he apply? Assume there is no friction.
Dmitry [639]

The correct answer is A. 250N

Work is a product of force and distance.

That is, work done=force×distance

Therefore substituting for the values in the question:

500J=force×2m

force= 500Nm/2m=250N

another unit for work done is Nm as force as the SI unit of force is newtons and distance in meters
