Answer:
0.169
Explanation:
There are three forces acting on the crate along the horizontal direction:
- The pushing force of the first worker, F1 = 450 N forward
- The pushing force of the second worker, F2 = 330 N forward
- The frictional force
acting backward
The crate slides with constant speed, so its acceleration is zero: a = 0. This means that we can write Newton's second law as

The frictional force can be rewritten as

where
is the coefficient of kinetic friction
m = 470 kg is the mass of the crate
g = 9.8 m/s^2 is the acceleration due to gravity
Substituting everything into the previous equation, we find:

Explanation:
The hypothetical upper limit to the mass a star can be before it self-destructs due to the massive amount of fusion it would produce is apparently as a result of <u>Eddington luminosity</u>
<h3>What are stars?</h3>
Stars are a fixed luminous point in the sky which is a large and remote incandescent body
So therefore, the hypothetical upper limit to the mass a star can be before it self-destructs due to the massive amount of fusion it would produce is apparently as a result of Eddington luminosity
