The object will fall through a distance of 638.45 m.
Considering the question given above, the following data were obtained:
Time (t) = 11.3 s
<h3>Height (h) =? </h3>
<u>NOTE</u>: Acceleration due to gravity (g) = 10 m/s²
We can obtain the height as illustrated below:
H = ½gt²
H = ½ × 10 × 11.3²
H = 5 × 127.69
<h3>H = 638.45 m</h3>
Therefore, the distance the object will fall is 638.45 m

The efficiency can never be 100 because some of the work will be transferred into thermal energy. In turn, causing the percentage to decrease. This is basically the second law of thermodynamics.
Rate of performing work is called power.
Time = work done/Power = 1800/300 = 6 sec.
Therefore it takes 6 secs to perform work.
Answer: A satellite with a mass of 110 kg and a kinetic energy of 3.08×10^9 J must be moving at a speed of 7483 m/s.
Explanation: To find the answer we need to know about the kinetic energy of a body.
<h3>
How to solve the problem the equation of kinetic energy?</h3>
- We have the expression for kinetic energy of a body as,
- We have to find the speed of the satellite,
Thus, we can conclude that, the velocity of the satellite will be 7438m/s.

Answer:
Explanation:
The bulk modulus is a constant that describes how resistant a substance is to compression.
It is defined as the ratio between increase in pressure and the resulting decrease in a volume of the material.
It is given by a formula :
OR
where:
& are the change in volume and change in pressure respectively.
V= original volume
According to the given:
So,
.................................(1)
&
..................................(2)
From the given conditions we compare equations (1) & (2):
cancelling the equal terms
The material in first case undergoes twice the volume reduction than that of the material in first case under the given conditions.
