<span>NASA launches another satellite into the exosphere. The atmosphere of the earth contains 5 layers, in order the troposphere, stratosphere, mesosphere, thermosphere and exosphere, the last two parts of the outer space being outside the ozone layer, and the exosphere is the last, since this is there Where the rockets are launched.</span>

Water behind a dam has a certain amount of stored energy that can be released as the water falls over the top of the dam. It may

Tpy6a [65]

Answer:

The answer is potential energy

Explanation:

The potential energy is the energy possessed by a body by virtue of it position

For example the water at the top of the dam is being held at a height h above the bottom of the dam

Then the potential energy

PE= weight of the water* the height

PE= m*g*h

1. Earth is approximately a sphere of radius 6.37х106 m. what are (a) its circumference in kilometers, (b) its surface are in sq

Minchanka [31]

As we know that circumference of the sphere is given as

$C = 4\pi R$

here we know that

$R = 6.37 \times 10^6 m$

now we have

$C = 4\pi (6.37 \times 10^6)$

$C = 8\times 10^7 m$

$C = 8 \times 10^4 km$

PART B)

surface area of the sphere is given as

$A = 4\pi R^2$

$R = 6.37 \times 10^3 km$

$A = 4\pi (6.37\times 10^3)^2$

$A = 5.1 \times 10^8 km^2$

PART C)

Volume of the sphere is given as

$V = \frac{4}{3}\pi R^3$

here we have

$V = \frac{4}{3}\pi(6.37 \times 10^3)^3$

$V = 1.1 \times 10^{12} km^3$

If a net horizontal force of 175 N is applied to a bike whose mass is 50 kg what acceleration is produced?

Crazy boy [7]

The acceleration of the bike is $3.5 m/s^2$

Explanation:

We can solve this problem by using Newton's second law of motion, which states that:

$F=ma$

where

F is the net force on an object

m is the mass of the object

a is its acceleration

For the bike in this problem, we have

F = 175 N is the net force

m = 50 kg is the mass

And solving for a, we find the acceleration:

$a=\frac{F}{m}=\frac{175}{50}=3.5 m/s^2$
