A student walks to school at a speed of 1.2 m/s if the student mass is 53 kg what is the students kinetic energy

Pls pls pls pls ! describe, in your own words, how you found the epicenter of the earthquake.

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.

Is the portion of the electromagnetic spectrum that has a frequency just above that of visible light.
