The unknown liquid has low H+ concentrations and high OH- concentrations.
The first thing you should know is that the friction force is equal to the coefficient of friction due to normal force.
Therefore, clearing the normal force we have:
The friction is 565N.
(565 / 0.8) = 706.25N. weight.

The second law of thermodynamics dictates that "</span>S<span>ome high-quality energy is always degraded.
It is important to know that the "Thermodynamics" is defined as a branch of physics that studies the m</span><span>echanical action of heat </span><span>and the others forms of energy.</span>
Answer:
Explanation:
vi = 200/5 = 40 m/s
a = (vf - vi)/t = (60 - 40)/20 = 1 m/s²
F = ma = 2000(1) = 2000 N
