How thick the liquids are. Maple syrup and cooking oil are very thick liquids, and water is generally runny.
Answer:
Even though the sun is much more massive and therefore has stronger overall gravity than the moon, the moon is closer to the earth so that its gravitational gradient is stronger than that of the sun.
Explanation:
(a)
Assuming the box is on a horizontal surface, the Normal Force would be equal to the Gravitational force which is 2.8 * 9.8 = 27.44N. You are already given the force, so we are ready to solve:


Since a coefficient of friction doesn't have units, your answer is 0.77.
(b)
We can use F = ma to get the Force, and then the same Normal force to get the kinetic coefficient of friction.

We can use that to formulate the kinetic coefficient of friction:


And those are your answers. Hope this helps. I'm not a college student, but I'm taking AP Physics, so I have an idea.
The force of a particle moving in a circular motion is:
F=ma
where m is the mass and a is the centripetal acceleration, which is expressed as:
a=v²/r
<span>where v is the speed and r the distance between the particles. You use these equations, by substituting the values given in order to solve the problem.</span>
Answer:
it's b
Explanation:
it's b cause ik I'm not wrong at these I did this when I was a kid and never got it wrong so it's b and will be cause b is the right answer so b it is
