<span>g = GMe/Re^2, where Re = Radius of earth (6360km), G = 6.67x10^-11 Nm^2/kg^2, and Me = Mass of earth. On the earth's surface, g = 9.81 m/s^2, so the radius of your orbit is:
R = Re * sqrt (9.81 m/s^2 / 9.00 m/s^2) = 6640km
here, the speed of the satellite is:
v = sqrt(R*9.00m/s^2) = 7730 m/s
the time it would take the satellite to complete one full rotation is:
T = 2*pi*R/v = 5397 s * 1h/3600s = 1.50 h
Hope it help i know it's long and may be confusing but if you have any more questions regarding this topic just hmu! :)</span>
The answer looks to be "A" because Protein is used to regulate organs.
Answer:

Explanation:
It is given that,
Radius of the circle, 
The area of the circle is given by :



or

As there is no uncertainty given in the radius of the circle. So, the area of the circle is
. Hence, this is the required solution.
Answer:
The length of an edge of each small cube is 3.43 nm.
Explanation:
Given that,
Temperature of ideal gas =27.0°C
Pressure = 1.00 atm
We need to calculate the length of an edge of each small cube
Using gas equation



For, N = 1
Where,
N = number of molecule
k = Boltzmann constant
T = temperature
P= pressure
Put the value into the formula


Now, for the cube





Hence, The length of an edge of each small cube is 3.43 nm.
