Answer:Net Force is zero
Explanation:
Given
Car is moving to the left with constant velocity i.e. net force on the car is zero
because change in velocity with respect to time is acceleration thus force is also zero because net acceleration is zero
Mathematically
acceleration
as velocity is constant therefore
thus a=0 , F=0
Answer:
1. K.E = 11.2239 kJ ≈ 11.224 kJ
2.
3.
Solution:
Now, the kinetic energy of an ideal gas per mole is given by:
K.E =
where
m = no. of moles = 3
R = Rydberg's constant = 8.314 J/mol.K
Temperature, T = 300 K
Therefore,
K.E =
K.E = 11223.9 J = 11.2239 kJ ≈ 11.224 kJ
Now,
The heat capacity at constant volume is:
Now,
Required heat transfer to raise the temperature by is:
