Un fluido de 6 kg se desplaza con una velocidad de 6 m/s. ¿Qué velocidad debe alcanzar para que realice una trabajo de 600 J?

An electron and a proton have the same kinetic energy upon entering a region of constant magnetic field and their velocity vectors are perpendicular to the magnetic field. suppose the magnetic field is strong enough to allow the particles to circle in the field. note: you'll need to look up the masses for an electron and proton. 1) what is the ratio of the radii of their circular paths rp/re?

Give one example to show that when substances are mixed,it may result in a chemical or a physical change depending on the conditions.

What is a subatomic particle with a negative charge and very little mass?
