Answer:
The value is 
Explanation:
From the question we are told that
The height of the water is 
The density of oil is 
The height of oil is 
Given that both arms of the tube are open then the pressure on both side is the same
So
=> Here
where 
is the density of water with value 
and 
is the atmospheric pressure
and
=> 
=> 
=> 
=> 
The difference in height is evaluated as
Mechanical advantage<span> <span>is a measure of the force amplification
achieved by using a tool, </span>mechanicaldevice or
machine system. Ideally, the
device preserves the input power and simply trades off forces against movement
to obtain a desired amplification in the output force. The model for this is
the law of the lever. So the ima is 3/1.5 = 2</span>
Earth distance to the Sun is about 40 times the Moon's distance from earth.
<u>Explanation:</u>
- The Earth's distance from the Sun is about 93 million miles. When it expressed in Km, it is 150 million Km.
- The Moon's distance from Earth is 238,855 miles. When it is 40 times then it will approximately equal to 93 million miles.
- The Sun's distance from Venus is 67.237 million miles. The Sun's distance from mercury is 35.832 million miles.
I think the answer is the kinetic energy decreases
