Please, I need it urgently.

An electron and a proton enter the same velocity in a uniform magnetic field oriented vertically upwards. The two particles enter the field in parallel directions, in the same direction, perpendicular to the field lines. We know the mass of the electron me = 9.1 * 10 ^ {- 31}and the mass of the proton mp = 63.1 * 10^{-27} . Draw the trajectories of the particles and calculate the ratio between the radii of these trajectories.

What is the equation for electrical work?

What happens when you slowly pulled the carboard?

Select light for the type of wave, adjust the wavelength so that the light is red, and increase the amplitude of the light to the max. then, select the start button at the source location to begin producing the waves. light is a form of electromagnetic wave, containing oscillating electric and magnetic fields. the wave amplitude detector mentioned above shows how the electric field oscillates in time at the location of the probe. the amplitude of the wave at the location of the probe is equal to the maximum electric field measured. how does the amplitude of the wave depend on the distance from the source?
