Well you have to minus the 4.5 to 5.2 and the answer to that would be -11.5 and calculated that to be 4.5
Transform boundary
is the answer from stemscopes
Answer:
This is your answer
Explanation:
Actually I took this from go ogle
Answer:
10581.59 V
Explanation:
We are given that
Magnetic field=B=0.65 T
Speed of electron=
Charge on electron, 
Mass of electron,
We have to find the potential difference in volts required in the first part of the experiment to accelerate electrons.

Where V=Potential difference
Mass of electron
v=Velocity of electron
Using the formula


Hence, the potential difference=10581.59 V
Answer:
The magnification is 133X
Explanation:
For a refractor telescope using convex lenses, the overall magnification os calculated as by dividing the focal length of the objective by that of the eyepiece.

So:

Care must be taken with the units, in this case they are in meters and centimeters, they should be converted into the same unit before calculating:
