Bob is designing two new bicycles. The bikes are identical except for the wheels. Bike 1 has solid wheels, mass M, radius R. Bik
e 2 has "hoop" wheels. The hoop wheels have the same mass, but that mass is situated as far as possible from the center.
Bob has decided to take each bicycle for a test ride. Assume Bob exerts the same effort to get each bicycle moving. Which bicycle will take longer to build up speed? Briefly explain/justify your answer with appropriate physics concepts.

Answer:
9.05 W
Explanation:
The given formula is where r is in centimeters and P is in Watts
Making Power, P the subject from the above formula
Substituting r with 12 cm then
Answer:
Given that
P = RT/V + a/V²
We know that
H= U + PV
For T= Constant (ΔU=0)
ΔH= ΔU +Δ( PV)
ΔH= Δ( PV)
P = RT/V + a/V²
P V= RT + a/V
dH/dV = d(RT + a/V)/dV
dH/dV = - a/V²
So the expression of dH/dV
b)
In isothermal process
(ΔU=0)
Now by putting the all values
ΔH = 17.06 L.atm
