To solve this problem, it is necessary to apply the concepts related to the change of entropy in function of the Volume in two states due to the number of moles and the ideal gas constant, this can be expressed as
Where,
R = Gas constant
V = Volume (at each state)
At the same time the number of moles of gas would be determined by the ideal gas equation, that is,
Where,
P = Pressure
V = Volume
R = Gas Constant
T = Temperature
Using the value of moles to replace it in the first equation we have
Therefore the correct option is A.
Answer:
initial speed is 13.36 m/s
Explanation:
given data
mass = 2 kg
velocity = 10 m/s
distance = 20 m
friction= 0.2
to find out
initial speed
solution
we find first friction force that is
friction force = friction ×mass×g ...........1
put here value
friction force = 0.2 × 2 × 9.81
friction force = 3.924 N
here a will be -ve due to friction
- friction force = mass × acceleration
acceleration = - friction force / mass
acceleration = - 3.924 / 2
acceleration = - 1.962 m/s²
and we know velocity formula that is
V² = V(i)² + 2as
put here value
10² = V(i)² + 2(-1.962)(20)
V(i) = 13.36
so initial speed is 13.36 m/s
