Answer: [tex]12.415 rad.s^{-1}[/tex]
Explanation: Angular velocity is the rate of change in angular displacement.
We know that:
Angular velocity, 
....................(1)
where:
= angular displacement in radians
<u>Given that:</u>
Putting the respective values in eq. (1)
<span>The correct answer is B. - It would take a ray of light 10.5 light years to travel from Earth to Epsilon Eridani, or vice-versa. Using our current technology it would take far longer than 21.0 years for a space ship from Earth to travel that far - I would have to guess many hundreds of years.</span>
Answer:
A. 2.2*10^-2m
Explanation:
Using
Area = length x L/ uo xN²
So A = 0.7m * 25 x 10^-3H /( 4π x10^-7*
3000²)
A = 17.5*10^-3/ 1.13*10^-5
= 15.5*10^-2m²
Area= π r ²
15.5E-2/3.142 = r²
2.2*10^2m
