Answer: E = 1.62*10^-3 v
Explanation:
Given
L = 1.9 m
V = 19 m/s
B = 4.5*10^-5 T
Induced emf can be found by using the formula for induced emf in a moving conductor.
e = blv, where
B is the component of the earth's magnetic field.
L is the width of the car in m
V is the velocity of the car in m/s
E is the induced emf in volts.
E = 4.5*10^-5 * 1.9 * 19
E = 1.62*10^-3 v
The drivers side is more positive, so the charge would remain positive
Answer:
0.38296 m
1.02132 rad
Explanation:
Angular frequency is given by
Displacement is given by
Velocity is given by
The phase angle is 1.02132 rad
The amplitude is 0.38296 m
The equation is given by
The equation is
I believe the answer is C, and not D because B is incorrect. The water and wind erosion smoothen the rock creating a mushroom shape.
Obviously, for its latitude.
The Lorentz force exerted on the particle due to the magnetic field provides the centripetal force that keeps the particle in circular motion:
where
m is the particle mass
v is its velocity
r its orbital radius
q its charge
B the magnetic field intensity
and where we neglected the factor
in the Lorentz force formula because the particle is traveling perpendicular to the magnetic field, so
.
Re-arranging the formula, we get
(1)
The problem gives us all the data about the particle and the magnetic field:
(we are only interested in the magnitude of the charge)
And by plugging these numbers into eq.(1), we find the radius of the orbit
