15. What is the magnitude of the magnetic field required to keep a proton moving in a circle of radius 1 at speed of 2.5x 10?m/s? (take mass of proton to be Mp=1.67x 107 kg)​

Avalue that describes how heavy an object is and is related to the force of gravity is

What must be the same for any two resistors that are connected in series ? a. the potntial diffrence across each b. the rate at which charge moves through each c. the rate at which energy is used by each d. the resistance to the flow of charge of each

Agas initially at p1 = 1 bar and occupying a volume of 0.5 liter is compressed within a piston–cylinder assembly to a final pressure p2 = 4 bar. (a) if the relationship between pressure and volume during the compression is pv = constant, determine the volume, in liters, at a pressure of 3 bar. (b) repeat for a linear pressure–volume relationship between the same end states. reference
