Answer:
19080667.0818 m/s
0.637294 m

Explanation:
m = Mass of deuterons = 
v = Velocity
K = Kinetic energy = 3.8 MeV
d = Diameter
B = Magnetic field = 1.25 T
q = Charge of electron = 
t = Time = 1 s
i = Current = 350 μA
Kinetic energy is given by

The speed of the deuterons when they exit is 19080667.0818 m/s
In this system the centripetal and magnetic force will balance each other

The diameter is 0.637294 m
Current is given by

The number of deuterons is 
Answer:
Determine the coordinates of two points on the line. Calculate the difference between these two locations' y-coordinates (rise). Calculate the x-coordinate difference between these two places (run). Divide the y-coordinate difference by the x-coordinate difference (rise/run or slope).
The AU ... Astronomical Unit ... used to be defined as the average distance between the Sun and Earth during the year.
Now it's defined as 149,597,870,700 meters exactly.
