Explanation:
Gas pedal is not required to used on friction less surface. On a friction less surface once the car is started and caused to move, car continues to move with same velocity as there is no opposing force. Therefore, no pressing of gas pedal required. However, this situation is not possible in real life, as friction is always present.
Answer:
Volume will increase by factor 2
So option (A) will be correct answer
Explanation:
Let initially the volume is V pressure is P and temperature is T
According to ideal gas equation
, here n is number of moles and R is gas constant
So
....................eqn 1
Now pressure is doubled and temperature is quadrupled
So new volume
........eqn 2
Now comparing eqn 1 nad eqn 2

So volume will increase by factor 2
So option (A) will be correct answer
I believe its E.
