The Coriolis effect is caused by earth's rotational forces. it is deflection of the object due to Coriolis forces (it is the inertial force,in physics which acts on the objects which are rotating). The deflection is a result of rotation of earth. this force act according to the rotating reference frame, if rotation is clockwise, it acts to the left.
Momentum is mass x velocity so...
Here we have the mass = 49.9kg
and the velocity = 5.78 m/s
So...
p = (49.9)(5.78)
p = 288.422 --> roughly 288.4 kgm/s
The current in the coil is 297 A
Explanation:
The magnetic field of a circular coil carrying a current is given by

where
is the vacuum permeability
N is the number of turns in the coil
I is the current in the coil
R is the radius of the coil
For the coil in this problem, we have:

R = 20 cm = 0.20 m
N = 15
Solving the equation for I, we find the current in the coil:

Answer:
14.001 in
Explanation:
Circumference = pi * diameter
Circumference / pi = diameter
44 inches/pi = 14.001 inches
i am right their with you i do believe it is A or D but i am more certain of D
