A boat heads in the direction N 79 deg E. The speed of the boat relative to the water is 25 mi/h. The water is flowing directly south. It is observed that the true direction of the boat is directly east. (Assume that the i vector points east, and the j vector points north.)

3. A laser spectroscopist produces benzene clusters by seeding benzene within helium in a supersonic expansion. Benzene and helium molecules are mixed within a gas cylinder and stored in a lab at 22°C. What is the relative speed of the benzene and helium molecules within the cylinder?

Which is greater -- the average speed or the most-probable speed? Explain why this is the case.

Please help

KE = -mv Consider the kinetic energy equation, where m is the mass and vis the velocity. If two gases have the same kinetic energy, KE, but one has a larger mass, what does that mean for the velocity of that gas, or diffusion rate? The velocity decreases as the mass increases. The velocity is negative. The velocity increases as the mass increases. The velocity is positive.

A cylinder measuring 2.1 cm wide and 2.5 cm high is filled with gas and the piston pushed down with a steady force. • piston cylinder gas Calculate the force on the piston if the pressure in the gas is measured to be 231. kPa.
