Answer:
Explanation:
Given
Volume of fixed chamber 
Initial Temperature 
Final Temperature 
Heat Supplied 
From First law of thermodynamics
Change in internal energy of the system is equal to heat added minus work done by the system

as the volume is fixed therefore work

thus 
for mono-atomic gas is 

and 1 mole contains 
thus No of molecules
No of molecules
Answer : The final pressure in the two containers is, 2.62 atm
Explanation :
Boyle's Law : It is defined as the pressure of the gas is inversely proportional to the volume of the gas at constant temperature and number of moles.

Thus, the expression for final pressure in the two containers will be:


where,
= pressure of N₂ gas = 4.45 atm
= pressure of Ar gas = 2.75 atm
= volume of N₂ gas = 3.00 L
= volume of Ar gas = 2.00 L
P = final pressure of gas = ?
V = final volume of gas = (4.45 + 2.75) L = 7.2 L
Now put all the given values in the above equation, we get:


Thus, the final pressure in the two containers is, 2.62 atm
You get the net force acting on it ... the sum of the strengths and directions
of all the individual forces there may be.
Answer:x=2 and x=3
Explanation:
Given
Potential Energy for a certain mass is

and we know force is given by


For Force to be zero F=0




Therefore at x=2 and x=3 Force on particle is zero.
Answer:
The acceleration of a boat if the resultant force on it is 4000 N and its mass is 1240 kg is 3.2 m/s².
Explanation:
Given
To determine
Acceleration a = ?
Important Tip:
- The acceleration of a boat can be found using the formula F = ma
Using the formula

where
- a is the acceleration (m/s²)
now substituting F = 4000, m = 1240 in the formula


Switch sides

Divide both sides by 1240

Simplify

m/s²
Therefore, the acceleration of a boat if the resultant force on it is 4000 N and its mass is 1240 kg is 3.2 m/s².
