Answer:
option (3)
Explanation:
According to the ideal gas equation
PV = nRT
where, P is pressure, V is volume, R is gas constant and T be the absolute temperature.
At constant volume,
P ∝ T
If the temperature is doubled, the pressure also doubled.
As volume is constant, so the density is also constant.
So, the pressure is doubled and the density remain constant.
Answer:
E) e
Explanation:
Impulse is equal to the product between the force applied (F) and the time interval of the collision (
):

This means that we can calculate the force for each collision dividing the impulse by the time interval:

Let's apply the formula to each case:
A) 
B) 
C) 
D) 
E) 
Therefore, the force is the maximum for collision E).
