Answer:
rpm= 916.7436 rev/min
Explanation:
First determine the perimeter of the wheel, to know the horizontal distance it travels in a revolution:
perimeter= π×diameter= π × 22 inches × 0.0254(m/inche)= 1.7555m
Time we divide the speed of the car, which is the distance traveled horizontally over time unit, by the perimeter of the wheel that is the horizontal distance traveled in a revolution, this dates us the revolutions over the time unit:
revolutions per time= velocity/perimeter
velocity= (60 mi/hr) × (1609.34m/mi) = 96560m/h
revolutions per time= (96560.6m/h) / (1.7555m)= 55004.614 rev/hr
rpm= (55004.614 rev/hr) × (hr/60min)= 916.7436 rev/min
Answer:
Explanation:
F = Force on the sled = 63 N
m = Mass of sled = 28.7 kg

By the isotherm process, the gas will dissolve in 4.5 atm.
It is important to know about isotherm conditions to solve this problem. The isotherm process is a cycle that has the same temperature but different pressure and volume. The process should follow the rule
P1 . V1 =P2 . V2
where P1 is initial pressure, V1 is initial volume, P2 is final pressure and V2 is the final volume.
From the question above, the parameter given are:
P1 = 2 atm
V1 = 1 L
P2 = 4.5 atm
By substituting the parameters to the rule, we get
P1 . V1 =P2 . V2
2 . 1 = 4.5 . V2
V2 = 2 / 4.5
V2 = 0.44 L
Hence, the gas will dissolve in 4.5 atm.
