What type of wave is formed by a sound wave?

In pulling two identical carry-on bags through the airport, Mr. Myers and his 13 year old grandson, Vincent, do the same amount

Novay_Z [31]

Answer:

Mr Myers and his son use the same force to pull the bags between the gates

Explanation:

The work done by Mr. Myers in pulling the carryon bags = The work done by his 13 year old grandson in pulling the identical bag

Let F₁ represent the force used by Mr Myers, and let F₂ represent the force F₂ used by his grandson

Let d represent the distance through the gate

Therefore, given that Work done, W = Force, F × Distance, we have;

The work done by Mr Myers between the gates, W₁ = F₁ × d

The work done by his grandson between the gates, W₂ = F₂ × d

Where, the work done by both Mr Myers and his grandson are equal, we have;

W₁ = W₂ and therefore, F₁ × d = F₂ × d, which gives;

F₁ = F₂, the force used by both Mr Myers and his son between the gates are equal.

A construction crane's cable lifts a 49.5-kg box upward with an acceleration of 1.30 m/s2. Find the tension in the rope.

Basile [38]

Verrrrry interesting question !

Force= (mass) x (acceleration)

 (49.5kg) x (1.3 m/s²) =

  Net force on the box is 64.25 newtons upward.

That's the net force. It's the combination of the tension in the rope
pulling the box up, and the force of gravity pulling the box down.

Force of gravity = "weight" = (mass) x (gravity) =

 (49.5) x (9.8) = 485.1 newtons downward

The tension in the rope must be enough to balance the downward force
of gravity PLUS provide another 64.25 newtons upward.

 Tension = (485.1) + (64.25) = 549.35 newtons
