Answer:
Explanation:
Magnetic Force on the rod F = Bi L
Work done by this force = F X d
= Bi Ld
This energy is converted into both rotational and linear kinetic energy
= 1/2 I ω² + 1/2 mv²
= 1/2 x 1/2 m r²ω²+ 1/2 mv²
= 1/4 m v² + 1/2 mv²
= 3/4 mv²
So according to conservation of energy
Bi Ld = 3/4 mv²
v = 
Answer:
Yes
Explanation:
The visible light color spectrum only makes up a small segment of the EM spectrum.
Answer:
- on the moon, they will fall at the time
- on earth, the coin will fall faster to the ground
Explanation:
A coin and feather dropped in a moon experience the same acceleration due to gravity as small as 1.625 m/s², and because of the absence of air resistance both will fall at the same rate to the ground.
If the same coin and feather are dropped in the earth, they will experience the same acceleration due to gravity of 9.81 m/s² and because of the presence of air resistance, the heavier object (coin) will be pulled faster to the ground by gravity than the lighter object (feather).
Set this up as a proportion.
.002 m^3/20 degrees = x/50 degrees
solve for x
x = .005 m^3
