You are at the controls of a particle accelerator, sending a beam of 1.80*107 m/s protons (mass m) at a gas target of an unknown element.

Sort the following forces as relevant or not relevant to this situation. The symbols are defined as follows: normal force = n⃗, tension force = T⃗, horizontal force of the road on the car = F⃗ rc, horizontal force of the road on the truck =

On Monday while Johnny was getting ready for school, he was in the bathroom holding his comb when he got an itch on his head. Johnny used the comb to rub his itch away and when he did his hair was a mess.

What does a velocity vs time graph look like for constant velocity if the speed is 2m/s. And the time is not given.

An electron and a proton, starting from rest, are accelerated through an electric potential difference of the same magnitude. in the process, the electron acquires a speed ve, while the proton acquires a speed vp. find the ratio ve/vp.
