Answer:
2) τ = F x torque increases, 3) troque decreases,
4) man approaches the pivot and the child must move away
5) Σ τ = 0
Explanation:
2) when the man moves away from the pivot his torque increases significantly, since his distance increases
τ = F x
τ = m g x
therefore the system rotates faster
3) when the child approaches the pivot, his troque decreases, because the distance decreases
τ = f x
therefore the system must spin slower
4) If we place the man and the child on the side of a scale, the movement must be the man approaches the pivot and the child must move away, so that the torque is the same and the system can reach a balance
5) the rotational equilibrium expression
Σ τ = 0
is the one that describes the equilibrium of a system with several forces
Answer:
<h2>675 N</h2>
Explanation:
The work done by an object can be found by using the formula
workdone = force × distance
From the question we have
workdone = 45 × 15
We have the final answer as
<h3>675 N</h3>
Hope this helps you
Answer: I can conclude that the more direct light/rays a material receives, the more heat it absorbs. The results support my hypothesis because the results show that the temperature of the soil is highest at the 90º angle of insolation. At this angle, the soil sample received the most direct rays and absorbed the most heat.
