Answer:
r = 0.0548 m
Explanation:
Given that,
Singly charged uranium-238 ions are accelerated through a potential difference of 2.20 kV and enter a uniform magnetic field of 1.90 T directed perpendicular to their velocities.
We need to find the radius of their circular path. The formula for the radius of path is given by :

m is mass of Singly charged uranium-238 ion, 
q is charge
So,

So, the radius of their circular path is equal to 0.0548 m.
Growing and being able to pollen
Answer:
0.83
Explanation:
to figure out what m/s is you would divide the distance by time.
1000 divided by 1200 is equal to .83 so
.83 m/s as your final answer
Answer:
"Speed" is the rate at which distance is being covered .... the ratio
of distance covered to the time it takes.
"Velocity" is the rate at which distance is being covered .... the ratio
of distance covered to the time it takes ... AND the direction in which
it is covered. 'Speed' with the direction of the motion.
