A container having a volume of 1 m holds
67th of helium gas at 147°C.-
Boltzmann's constant is 1.38 x 10-23 J/K.
Assuming the helium behaves like an ideal
gas, what is the average kinetic energy per
molecule?
Answer in units of J.

When someone slams her books on a table the kinect energy is transferred into vibrations that travel to your ears as sound waves which statement describes the movement of those waves

In an experiment, how can i change human errors? be specific.

Avertical clean glass piezometer tube has an inside diameter of d = 1 mm and is used to measure pressure in a horizontal pipe carrying water as shown. due to pressure in the pipe, the water at 20c rises into the tube to a height h. if the water pressure in the pipe is p = 500 pa gauge, estimate the height h: (a) without considering surface tension (b) with surface tension (capillary) effects. the contact angle  can be assumed at 30 deg
