Answer:
the angle of the prism = 30 degrees
Explanation:
The angle of minimum deviation for a prism =
<em>for an equilateral prism, A=60∘</em>
<em />
This gives us
taking the Arcsin of both sides we have
Recall that the angle of the prism is equal to the angle of minimum deviation.
Hence, the angle of the prism = 30 degrees
The distance between two points on a graph is
Square root of [ (difference in the y-values)² + (difference in the x-values)² ] .
So for these two points, the distance between them is
square root of [ (-5)² + (12)² ] =
square root of [ 25 + 144 ] =
square root of [ 169 ] =
<em>13 .</em>
Yes, the ' 13 ' you typed at the end of the question is the correct answer to it.
Answer:
0.075 T
Explanation:
When a current-carrying wire is immersed in a region with magnetic field, the wire experiences a force, given by
where
I is the current in the wire
L is the length of the wire
B is the strength of the magnetic field
is the angle between the direction of I and B
In this problem we have:
L = 0.65 m is the length of the wire
I = 8.2 A is the current in the wire
F = 0.40 N is the force experienced by the wire
since the current is at right angle with the magnetic field
Solving the formula for B, we find the strength of the magnetic field:
