A sealed 12 m3 tank is filled with 6000 moles of ideal oxygen gas (díatomic) at an initial temperature of 270 K. The gas is heated to a final temperature of 340 K. The atomic mass
of oxygen is 16.0 gmol. The mass density of the oxygen gas, in SI units, is closest to:

Complete the sentence to describe the law of conservation of energy. the law of conservation of energy states that energy cannot be created or , but it can be

An electron is ejected into a horizontal uniform e⃗ field at a parallel horizontal velocity of v0. assume the electron's initial position x0, initial velocity v0, time t, magnitude of electric field e, electron's mass m, and the magnitude of the electron's charge |e|. ignore the force that earth exerts on the electron. assume the e⃗ field is in the same direction as the initial velocity. part a define the equation for the electron's velocity. express your answer in terms of the variables v0, |e|, t, e, and m.

If you let go of the notebook after lifting it, will it move? how?
