Answer:

A crane operator drops the cargo by turning off the electric current to the electromagnet. Electromagnets can be controlled by controlling the electric current. An electromagnet is stronger if there is more current flowing through it.

How much work is done by the gravitational force on the block?
KatRina [158]

Answer:

Work = Mass * Gravity * Height and is measured in Joules. Imagine you find a 2 -Kg book on the floor and lift it 0.75 meters and put it on a table. Remember, that “force” is simply a push or a pull. If you lift 100 kg of mass 1-meter, you will have done 980 Joules of work.

aliina [53]

Answer:

Centripetal acceleration = 1.46m/s²

Explanation:

Given r = radius = 50m

v = distance/time = 200m/23.4s = 8.55m/s

Acceleration = v²/r = 8.55²/50 = 1.46m/s²

A feather of mass 0.001 kg falls from a height of 2 m. Under realistic conditions, it experiences air resistance. Based on what
guajiro [1.7K]
Explanation:

Two objects that only have the force of gravity acting on them, will fall with the same acceleration <span>g=9.8<span>m<span>s2</span></span>; g=32.2<span><span>ft</span><span>s2</span></span></span> and will therefore hit the ground at the same time.

When you drop a feather, air resistance acts on all the surfaces of the feather. This causes the feather to slow down.

Air resistance depends on two factors: the speed of the object (increased for example by throwing it), and its surface area.



hope this can give u a little bet more to know about how to get ur answer :P 

have a gud day and gud luck!
