Answer:
the particle experiences maximum force when it will be moving perpendicular to magnetic field.
it experiences minimum deflecting for when its going parallel to the magnetic field.
Explanation:when a charged particle is moving
magnetic field is B which is a vector
Magnetic force on a charge is F
formula for force F =Q.(VxB)
magnitude of the charge particle is Q
the vector multiplication of (VxB) if most significant when the charge particle is moving parallel.Very minimum when moving
velocity of the charge particle is V
1) Equivalent resistance, 1/R = 1/15 + 1/40 + 1/60 = 8+3+2 /120 = 13/120
R = 120/13 = 9.23
2) Current, I = V/R = 115/9.23 = 12.45 A
Answer:
0.3J
Explanation:
pe = mgh = 0.006 x 10 x 5 = 0.3j
Answer: - 3.43 m/s^2
Explanation:
1) Acceleration = [change in speed] / [time elpased]
2) Change in speed = final speed - initial speed
Since the car comes to a complete stop, the final speed is 0
3) time = 7 seconds
4) Calculation:
acceleration = [ 0 m/s - 24 m/s] / 7 s = - 24 m/s / 7 s = - 3.43 m/s/s or - 3.43 m/s^2
The negative sign means that the car decelerated.
The amount of work done by a certain body is the product of the power given and the time. Mathematically,
Work = Power x time
Substituting the known values,
Work = (150 W) x (10 s)
= 1500 N.m
= 1500 J
