Answer:
33333.35 kg
Explanation:
I got it right on Acellus, rounded to 33300 sigfigs
Answer:
The wavelength of the light is 562.5 nm
Solution:
As per the question:
Order, n = 1
Slit separation, d = 
Distance from the bright fringe, y = 0.18 m
Distance between the screen and the grating, D = 0.8 m
Now,
We know from the eqn for diffraction:
n = 1
(1)
Also,
For very small angle, 
:
≈ 
Using the above value in eqn (1):
<span>The
answer is towards <span>the poles. This is because, at
the poles of the magnet, the magnetic field lines get closer together hence
indicating that the magnetic force is stronger here. The fields are closest
together at the center of the magnet and farthest at the outside side of the
magnet. </span></span>
A). The drawing looks like a ladder with 4 rungs.
One rung is a 90-volt battery.
The other 3 rungs are the 3 resistors.
b). The equivalent resistance is the reciprocal of (1/15 + 1/30 + 1/60).
That's the reciprocal of 7/60, or about 8.571... ohms.
c). I = V/R = 90 / 8.571... = 10.5 Amperes.
d). The 60-ohm resistor is connected directly across the battery.
Power = V²/R = (90²) / 60 = 135 watts. Better COOL that baby !
Answer: 6.66666667 or 6.66 km per hour
Explanation: (velocity = distance÷time) or (v=d÷t)
