Concave lens. These are used in making the objectives of reflection telescopes
In my opinion, calling exercise "work" wouldn't be a good way of describing it, I don't think people would exercise if its called work
Answer:
A parallel circuit has two or more paths for current to flow through.
Voltage is the same across each component of the parallel circuit.
The sum of the currents through each path is equal to the total current that flows from the source.

Answer:
You will have to move 12.2 ft to decrease the initial intensity to 17 mRem/h.
Explanation:
The distance can be calculated using the following equation:
<u>Where</u>:
I₁ = 158 mRem/h
I₂ = 17 mRem/h
D₁ = 4 ft.
D₂=?
Hence, the distance D₂ is:
Therefore, you will have to move 12.2 ft to decrease the initial intensity to 17 mRem/h.
I hope it helps you!
Answer:
Explanation:
Potential difference is created when a long object of length l moves perpendicular to magnetic field . The potential difference created is
V = Blv where B is magnetic field , l is length and v is velocity of length l .
here V = 45 x 10⁻⁶ x 44000 x 1.2
= 2.376 volt .
b )
Electric field = V / l ; V is potential difference between length l .
= 2.376 / 44000
= 54 x 10⁻⁶ V/m
