Answer:
i think its because u gave the almost every answer the same exact thing. all the questions have different ways of moving which means different forces for each one i hope this helps :)

This would be called the law of action-reaction. This states that every action will have an equal and opposite reaction. The action in the example is pulling down on the rope. The opposite and equal reaction is the climers body moving upward. The same law can be applied to a rocket. The action is the engines pushing down and the reaction is the rocket going up. :D
Answer:
The magnitude of the angular acceleration is α = (3 * F)/(M * L)
Explanation:
using the equation of torque to the bar on the pivot, we have to:
τ = I * α, where
I = moment of inertia
α = angular acceleration
τ = torque
The moment of inertia is equal to:
I = (M * L^2)/3
Also torque is equal to:
τ = F * L
Replacing:
I * α = F * L
α = (F * L)/I = (F * L)/((M * L^2)/3) = (3 * F)/(M * L)
Answer:
Florence is often named as the birthplace of the Renaissance. The early writers and artists of the period sprung from this city in the northern hills of Italy. As a center for the European wool trade, the political power of the city rested primarily in the hands of the wealthy merchants who dominated the industry
