Unbalanced forces is the correct answer.
Explanation:
<span>When reading a buret, the initial reading should be taken from the top of the glassware and the final volume should still taken at the top. If the buret is completely, the initial volume for most buret would be zero. though, there are some where their initial starts at 50 decreasing to zero.</span>
Answer:
The acceleration of man 1 and 2 is 
and 
.
Explanation:
Mass of man 1, m₁ = 80 kg
Mass of man 2, m₂ = 60 kg
One man pulls on the rope with a force of 250 N.
Let a₁ is acceleration of man 1,
F = m₁a₁
Let a₂ is acceleration of man 1,
F = m₂a₂
So, the acceleration of man 1 and 2 is and .
