Ipatiy [6.2K]3 years ago
4 0
Well, the focal length is a distance to the point in which all of the rays of a parallel beam cross. Since a parallel beam reflected by the mirror is still parallel and does not converge, no matter how far from the mirror it travels, the focal distance of a mirror is

f = -∞

minus sign denotes that the image in the mirror is imaginary

In this experiment you will investigate which of the following properties of Faraday's law of electromagnetic induction? (Select
11Alexandr11 [23.1K]

Answer:

Answered

Explanation:

Part A

According to Faraday's law the induced emf in coil is equal to negative of its rate of change of magnetic flux time the number of turns in the coil.

\epsilon = -N\frac{d\phi}{dt}= -N\Delta\frac{BA}{\Delta t}

When an emf generated by a change of magnetic flux, produced current of whose magnetic field opposes the change  which produces it.

By the above equation the correct options are 1,2 and 4

Part B

Large signals of  frequency of 60Hz are measured by osciloscope.

Hence the correct option is part 1.
