Answer:

The question is incomplete.

It asks you to use the formula W = F * D (force times distance)

But the question only gives the work W in joules.

You would need to know the weight of the object to get the distance moved or the distance moved to get weight if you are only given the work done.

Incidentally, the mechanical advantage in diagram is A is 1 whereas the mechanical advantage in B is 2.

So in B you would apply 1/2 the force as in A and would have to move the rope twice as far as in A to do the same amount of work.

How does altitude, distance from the ocean, amount of sunlight, distance from the equator, and ocean currents affect polar clima

drek231 [11]

The altitude is usually low. Tropical places are mainly on the ocean, that's usually why it's so hot. They are usually close to the equator, but not right on it. The tropics get a lot of direct sunlight, so wear that sunscreen! The ocean currents are warm, so they bring along warm water. All of those help make the tropics the way they are.

A closely wound rectangular coil of 75.0 turns has dimensions of 22.0 cm by 45.0 cm . The plane of the coil is rotated from a po

pentagon [3]

Answer:51.52 V

Explanation:

Given

N=75 turns

$Area=22\times 45 cm^2$

$\theta =36^{\circ}$

$Emf induced =-N\frac{\mathrm{d}\phi }{\mathrm{d} t}$

$Emf=-75A\frac{B_2-B_1}{t}$

$Emf=-75\times 22\times 45\times 10^{-4}\frac{1(1-cos(90-36))}{6\times 10^{-2}}$

Emf=51.52 V
