A) Its mass
I think this is the answer because if another planet had a bigger mass the other planets and the sun itself would orbit it. I am not sure though this is my best guess.
Speed is the rate at which an object's position changes, measured in meters per second. The equation for speed is simple: distance divided by time. You take the distance traveled (for example 3 meters), and divide it by the time (three seconds) to get the speed (one meter per second).
Answer:
Speed of the proton is
Explanation:
It is given that,
Magnetic field, B = 1.35 T
Radius of circular path, r = 0.072 m
The centripetal force is balanced by the magnetic force such that,
q and m is the charge and mass of a proton respectively
So, the speed if the proton is . Hence, this is the required solution.
Answer:
you can use a balance

when you tend to measure something you are using your brain so why dont you use your brain dimwitt
