Answer: 20 m/s in 2 significant figures.
Explanation:
Initial velocity (u) = 0 m/s
Acceleration by gravity (a) = 9.81 m/s^2
Displacement (s) = 20m
Final velocity (v) = ?
Now, use formula
v^2 = u^2 + 2 * a * s
or, v^2 = 0^2 + 2 * 9.81 * 20
or, v = square root of( 2 * 9.81 * 20 )
So, v = 20 m/s in 2 significant figures.
Answer:
where
Pa = Gravitational potential energy of satellite A
Pb = Gravitational potential energy of satellite B
G = gravitational constant
Me = Mass of the earth
Ma = Mass of satellite A
Mb = Mass of satellite B
Re = Radius of the earth
Pb/Pa = (-GMeMb/Re) / (-GMeMa/Re)
Pb/Pa = Mb/Ma
Explanation:
There's no such thing as a "cubic gallon". A 'gallon' is already a unit of volume,
only without the word 'cubic' in it.
If you like to play with different units of measure, here are a few conversions:
1 gallon = 231 cubic inches
1 cubic foot = 1,728 cubic inches = about 7.4805 gallons
1 cubic meter = 1,000 liters = 1 million cubic centimeters = about 264.17 gallons
