Answer: 9.0 atm
Explanation:
To calculate the new pressure, we use the equation given by Boyle's law. This law states that pressure is directly proportional to the volume of the gas at constant temperature.
The equation given by this law is:
where,
are initial pressure and volume.
are final pressure and volume.
We are given:
Putting values in above equation, we get:
Thus new pressure of 150 ml of a gas that is compressed to 50 ml is 9.0 atm
Answer:
6.96 s
Explanation:
The period of a simple pendulum is given by:
where
L is the length of the pendulum and g the acceleration due to gravity.
In this problem, we have a pendulum with length L = 2.00 m, while the acceleration due to gravity is 1/6 that of the earth:
So, the period of the pendulum on the moon is
