The Correct answer to number 1 is A or D
The correct answer to number 2 is C because transmission meaning is to travel.
PS. I think number 1 is D
≈ 746 watts is a 1 Horsepower, because that's in the SI base unit.
The gravitational force acting upon the woman is equal to <u>-588.6N</u>
Why?
To solve the problem, we need to consider that two forces are acting upon the woman, the first one is related to her weight and the second one is related to the acceleration of the elevator.
Gravitational force acting upon the woman:

Hence, we have that the gravitational force acting upon the woman is equal to -588.6N.
Have a nice day!
Particle kinetic energy and particle speed
we are given in the problem the following dimensions or specifications
B = 0.000055 T r = 0.25 m constant mu0 = 4*pi*10-7
The formula that is applicable from physics is
B = mu0*I/(2*pi*r) I = 2*B*pi*r/mu0 I = 68.75 Amperes
