The force of friction is 78.4 N
What is force of friction?
Frictional force is the force created when two surfaces come into contact and slide against each other. it is given by the equation:
μ * 
where,
= force of friction
μ = coefficient of friction
= normal force
Given,
μ 
We know,
Subsituing the values in equation:
μ *
The force of friction is 78.4 N.

When the Moon passes between Sun and Earth, the lunar shadow is seen as a solar eclipse on Earth. When Earth passes directly between Sun and Moon, its shadow creates a lunar eclipse. Lunar eclipses can happen only when the Moon is opposite the Sun in the sky, a monthly occurrence we know as a full Moon.
<h3>The correct answer is:</h3><h2>9.08 x 10⁶ meters.</h2><h2 /><h3>Explanation:</h3>
Fg = 2.58 x 10³ N
Mv = 4.87 x 10²⁴ Kg
Md = 655 Kg
So, Fg = G Mv Mp / r²
By putting in the values,
r² = 8.2466 x 10¹³
<h2>r = 9.08 x 10⁶ meters.</h2>
