Incomplete question as number of moles and length is missing.So I have assumed 3 moles and length of 0.300 m.So the complete question is here:
Three moles of an ideal gas are in a rigid cubical box with sides of length 0.300 m.What is the force that the gas exerts on each of the six sides of the box when the gas temperature is 20.0∘C?
Answer:
The Force act on each side is 2.43×10⁴N
Explanation:
Given data
n=3 mol
L=0.3 m
Temperature=20.0°C=293 K
To find
Force F
Solution
To get force act on each side it would employ by
F=P.A
Where P is pressure
A is Area
First we need to find pressure by applying ideal gas law
So
So The Force is given as:
The Force act on each side is 2.43×10⁴N
Taking specific heat of lead as 0.128 J/gK = c
We have energy of ball at 7.00 meter height = mgh = 
When leads gets heated by a temperature ΔT energy needed = mcΔT
= 
ΔT
Comparing both the equations
= ΔT
ΔT = 0.536 K
Change in temperature same in degree and kelvin scale
So ΔT = 0.536 
The given statement is true.
Pressure is defined as force per unit area.
In mathematical terms,
Pressure = force/area
pressure is directly proportional to the force on the object
pressure is indirectly proportional to the area on which force acts
Hence the given statement is true

It is given that the height of the tower is
The uncertainty the measurement of this height is
Drop time is measured as:
The uncertainty in measurement of time is:
Using the equation of motion: 
where, 
is the distance covered, 
is the initial velocity, 
is the acceleration and 
is the time.
(because canon ball is in free fall). we need to calculate the value of a=g.
The uncertainty in this value is given by:
Substitute the values:
Work = (force) x (distance)
Power = (work) / (time)
Knowing force, distance, and time, it looks like
you can calculate both <em>work and power</em>.
But that's not all !
-- <u>Speed</u> = (distance) / (time)
-- <u>Impulse</u> = change in momentum = (force) x (time)
