F = ma
You need to rearrange this equation to find mass so you would have the equation :
M = f/a
Input the numbers into the equation :
M = 56/7
M = 8
Preasure at the bottom would be Air Pressure at the top added to the pressure due to the water height.
so pressure = air pressure + hdg
where,
h = depth of the lake, (432ft into metres)
d = density of water (1000kg/m^3)
g = 9.81 m/s^2 (approx.)

Answer:
Uranus and Neptun are outer planets od the Solar system, since they are located after the asteroid belt. All of these outer planets are much larger then the inner ones so they are called the "ice giants". The other reason for this name is that they are very far from the Sun, so their temperature is low. Another feature they have in common is their atmosphere which is composed of gases, including methane, which is responsible for their blue color, since methane absorbs red light. However Neptune is known for very fast winds and storms in its atmosphere which is responsible for its high activity and changes.
So, the blanks should be filled with:
Sun
methane
Neptune
outer planets
Answer:
C) 1200 rpm
Explanation:
= Diameter of bigger pulley = 24 inch
= Diameter of smaller pulley = 8 inch
= Speed of bigger pulley = 400 rpm
= Speed of smaller pulley
The relation between revolutions per minute and diameter is that they are inversely proportional.
The number of revolutions per minute of the smaller pulley is 1200 rpm
