Answer:
a. 7.38 N b. 40.87 N c. 0.113 kg-m²
Explanation:
Answer:
The answer is A.
Explanation:
The diagram shows the light ray bending away from the normal. Light rays bend away from the normal when their speed increases. This means that in the diagram, the light ray moves from a medium in which light has a lower speed to a medium in light has a higher speed. The only choice where the speed of light increases from A to B is answer A. So that has to be the answer.

Answer:
The magnitude of the electric field equal to 2.40 N/C at 1.1537m from the wire.
Explanation:
using Guass law,
(guessing that a cylinder of radius r and length L around wire such that wire is at centre )
E. A = qin / e0
E ( 2πr L ) = (1.56 x 
x L) / (8.85 x 
)
E = (1.56 x ) / (2πr x 8.85 x )
so 2.40 = (1.54 x ) / (2πr x 8.85 x )
2.40 (6.284r) = 0.174 x 10²
15.0816r = 17.4
r = 1.1537m
