The correct answer will be:
Planetary system.
To solve this problem, we must take two important steps. First we will convert all the given units, to international system. Later we will define the torque, which is given as the product between the radius of application of the force and the Force acting on the body. Mathematically the latter is,
Here,
r = Radius
F = Force
Now the units,
Replacing,
Therefore the torque that the muscle produces on the wrist is
The impact would be great it would possibly freeze the work or melt the polar ice caps and flood the world to were we would invent technology light years away.
Answer:
80 J
Explanation:
PE = mgh
PE = (4 kg)(9.8 m/s^2)(2 m)
PE = 78.4 J and with sig figs, it would be 80 J
