Two glass vessels M and N are connected by a closed valve. M
i
N
M contains helium at 20°C at a pressure of 1* 10 Pa N has been evacuated, and has three
times the volume of M. In an experiment, the valve is opened and the temperature of the whole
apparatus is raised to 100°C
What is the final pressure in the system?
A
3.18 10Pa
B
4.24 10'Pa
C 1.25 X 10 Pa
D 5.09 10 Pa

Explanation:

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
