2. How much Potential Energy is gained when a 1250 N mass is raised a vertical distance of<br>35 m?

vichka [17]

Potential Energy

The potential energy gained is 43750 J

Explanation:

Potential energy is the energy by virtue of an object's position relative to the ground ie, the height of the other object.

For example, an object has more potential energy when it is on top of a two-story building than it does resting on the ground. That's because the object's relative position to the Earth gives it more energy.

Potential Energy is defined as

Potential energy = Mass * height

Given Mass M = 1250 N

Given height h = 35 m

So the potential energy = 1250 * 35 = 43750 J

Thus the potential energy is 43750 J

The distance from Alexandria to Syene is about 500 miles. On the summer solstice the sun is directly overhead at noon in Syene.

svp [43]

Answer:

Earth circumference is 25000 miles

correct option is 25,000 miles

Explanation:

we have given here Alexandria to Syene distance = 500 miles

the sun is 1/50th of the circumference of the sky (about 7°)

as we know that Earth circumference done by astronomer Eratosthenes in 240 B.C

He observe on a particular time of day ( in noon) during the summer solstice

and there was no shadow in Syene in Egypt so This was verified that the sun must be directly on overhead and not at an angle to the surface of the city at that time

so

In Alexandria he measured the position of sun at the same time and found it to be nearly (1/50)th of a complete circle

it would be 7.2 degree (when we do $\frac{360}{50}$ = 7.2)

so 2 reference points being 2 cities for the sun

all measure circumference = the distance between these two cities × 50

and we have given 500 miles

so

Earth circumference = 500 × 50

Earth circumference is 25000 miles

correct option is 25,000 miles
