B. 8 is the answer but sometimes its determined by the quantum numbers on the chart
All magnetic fields are created by moving charged particles. So guessed Particles produces magnetic field (electric Currents)
You use the right hand rule. With your thumb out and the rest of your fingers curved ( like a thumbs up) curve your fingers to the direction of the torque. The direction your thumbs points at is the direction of the torque
Explanation:
a)
The circumference of the path is:
C = 2πr
C = 2π (0.235 m)
C = 1.48 m
Velocity = displacement / time
v = 1.48 m / 1.95 s
v = 0.757 m/s
b)
1 rev / 1.95 s = 0.513 Hz
c)
1 rev / 1.95 s × (2π rad / rev) = 3.22 rad/s
Answer:
Explanation:
Let λ be the required wavelength.
Two fringe patterns will be formed on the screen which will overlap each other. Let 9 th bright fringe of first coincides with 11 th bright fringe of second.
position of 9 the bright fringe of first = 9x 646 x D/d nm
position of 11 th bright fringe of second pattern = 11 x λ x D/d
now , 9 x 646 = 11 x λ
λ = 9 x 646 / 11 = 528.54 nm.
