A 4.0 kg mass is moving along the x axis. The potential energy curve as a function of position is shown. The kinetic energy of the object at the origin is 12 J. The system is conservative. There is no friction. (a) What will be the kinetic energy at 2.0 m along the x axis?

(b) What will be the speed of the object at 6.0 m along the x axis?

PLEASE help​

Which of the following represents an upright image? a. -do b. +m c. -m d. +do

Awelder using a tank of volume 7.50×10^-2 m^3 fills it with oxygen (with a molar mass of 32.0 g/mol ) at a gauge pressure of 3.30×10^5 pa and temperature of 37.1 ∘c. the tank has a small leak, and in time some of the oxygen leaks out. on a day when the temperature is 23.1 ∘c, the gauge pressure of the oxygen in the tank is 2.00×10^5 pa . a) find the initial mass of oxygen. b) find the mass of oxygen that has leaked out.

When flexing to a reflective style, one should be specific, brief and to the point, and maintain a fast and decisive pace?
