Answer is given below
Explanation:
given data
pressure = double
volume = constant
solution
As we know that an Average velocity and rms velocity is directly proportional to square root of PV ..................1
so if we take P is doubled while keeping V constant
than Velocity increases by a factor
so that Factor = 1.414 for both the cases
Answer:
The one with highest velocity
Explanation:
The momentum of an object is given by
where
m is the mass of the car
v is the velocity of the car
In this problem, we have two identical cars: identical means they have same mass, so
The momentum of car 1 is
while the momentum of car 2 is
By comparing the two expressions, we see that the car with greatest momentum is the one with highest velocity, since the mass is the same.
