B.) How many people were included in the study?

This is the best answer, as the more people there is, a greater variety of choices is possible, leading to a better result that can usually apply to a larger population.

hope this helps

A cosmic ray electron moves at 7.65 ✕ 106 m/s perpendicular to the Earth's magnetic field at an altitude where field strength is
mariarad [96]

Answer:

Radius = 3.96m

Explanation:

In a cyclotron motion, the radius of a charged particle path in a magnetic feild is given by:

r = mv/qB

Where r = radius

m = mass of particle= 9.1×10^-31kg

q = charged electron = 1.6×10^-19C

B = magnetic feid = 7.65×10^6T

V = velocity = 7.65×10^6

r = (9.1×10^-31)×(7.65×10^6) / (1.6×10^-19)(1.10 ×10^-5)

r = (6.9615×10^-24)/(1.76 ×10^-24)

r = 3.96m
