Image distance (Di) = 17 cm
Object distance (Do) = 36 cm

Using mirror equation,

1/Di + 1/Do = 1/f
1/17 + 1/36 = 1/f
0.058824 + 0.027777 = 1/f
1/f = 0.086601
f= 11.5472 = 11.55 cm

enot [183]

Answer:

60°

Explanation:

Formula

360/n (if the number is an odd number) or

360/n-1 (if the number is even) (to arrive at an odd number)

SO. 5 is an odd number but not a multiple of 360, so we will use 6 an even number.

360/60-1

360/60=6 images

6-1 =5 images

Thus. the images formed will be 5.

harkovskaia [24]

Answer:

b) Demultiplexer.

Explanation:

The multiplexed signal occupies the total bandwidth of the communications channel, while that the constituent component signals, occupy only a small part of the bandwidth.

Prior to be demodulated, they must be separated each other, which is done (in a FDM multiplexing scheme) using a series of band-pass filters.
