Acosmic ray electron moves at 6.5 x 106 m/s perpendicular to the earth’s magnetic field at an altitude where field strength is 1.24 10-5 t. what is the radius (in meters) of the circular path the electron follows? the charge of an electron is 1.6 x 10-19 c and its mass is 9.11 x 10-31m. your answer should be a number with two decimal places, do not include the unit.

R=2.98 m

Explanation: In order to solve this answer we have to use the dynamic of circular movement actioned by the Lorentz force, this is given by:

Fm=qvB ( condiring that v and B are perpendicular)

By using the second Newton law fro a circular movement, we have:

Fm=m*a=m*v^2/R  where v and R are the speed and R of the circular movement electrons in the magnetic field.

then

qvB=m*v^2/R

Finally R=m*v/(qB)=9.11*10^-31*6.5*10^6/(1.6*10^-19*1.24*10^-5)=2.98

emily ruth's annual premium is $1058.50

step-by-step explanation:

emily ruth is a female of 27 years age purchasing 20 year endowment insurance with face value $25000.

from the given table,

for females, the age of a male 3 years younger should be used.

so, we have to check for 24 year male for 20 year endowment.

it is 42.34 for every $1000 face value.

for a face value of $25000,

it is 25 * 42.34 = $1058.50

∴ emily ruth's annual premium is $1058.50
