What is the speed of a high-speed electron traveling at right angles to a 0.80-tesla magnetic field with a force of -7.5 x 10^-1
serg [7]

Explanation:

Answer:

Magnetic field, B = 0.016 Tesla

Explanation:

It is given that,

Velocity of electron, v=9.6\times 10^5\ m/sv=9.6×10

5

m/s

Magnetic force, F=2.6\times 10^{-15}\ NF=2.6×10

−15

N

Charge, q=1.6\times 10^{-19}\ Nq=1.6×10

−19

N

The magnetic force is given by :

F=qvBF=qvB

B=\dfrac{F}{qv}B=

qv

F

B=\dfrac{2.6\times 10^{-15}}{1.6\times 10^{-19}\times 9.6\times 10^5}B=

1.6×10

−19

×9.6×10

5

2.6×10

−15

B=0.016\ TB=0.016 T

So, the magnitude of magnetic field is 0.016 Tesla. Hence, this is the required solution.

I need help on #9 (it's side ways sorry...)
Gennadij [26K]
<span>All of these are directly proportional to each other, meaning that if one goes up or down, they all do the same.
So if the temperature increases so does the heat. If the heat increases then so does the thermal energy. If the temperature goes up then so does the thermal energy. ETC...</span>
