Answer:
Book of mass 2 kg is lifted from floor to the table. The height between floor and the table is 1.5 m. Calculate the work done by gravitational force.
Answer:
ANS : .Energy spent on spraying =
Explanation:
<em>Given:</em>
- <em>Radius of mercury = 1cm initially ;</em>
- <em>split into
drops ;</em>
Thus, volume is conserved.
i.e ,

- Energy of a droplet =
Δ
Where ,
- <em>T is the surface tension </em>
- <em>ΔA is the change in area</em>
Initial energy 
Final energy 
∴ .Energy spent on spraying = 
ANS : .Energy spent on spraying =
The second law of motion states that: the acceleration of an object is dependent upon two variables: - the net force acting upon the object and the mass of the object. The acceleration of an object depends directly upon the net force acting upon the object
<h3>Meaning of Motion</h3>
Motion can be defined as the process of changing position willingly or due to a force applied.
Motion can be seen in different forms and types depending on the object.
In conclusion, The second law of motion is used to deduce the formula for acceleration.

Answer:
Because the object should shrink its volume to zero, which is impossible
Explanation:
Let's talk about gases for simplicity. Ideal gases are governed by the ideal gas equation:

where
p is the gas pressure
V is the volume of the gas
n is the number of moles
R is the gas constant
T is the absolute temperature
From the formula, we see that T and V are directly proportional: therefore, in order for a gas to have an absolute temperature of zero, it must also have a volume of zero, which is impossible.
