Answer:
a. Point A
b. 20 V
c. 100 J
Explanation:
a. Point A is at a higher potential because there is a positive sign in front of its magnitude. Since it is a positive integral value, and has a higher magnitude than point B which is at -4, point A is thus at a higher potential than point B.
b. The potential difference between the two points ΔV = A - B
= +16 V - (-4 V)
= +16 V + 4 V
= + 20 V
c. The work done, W in moving a charge Q across a potential difference ΔV is W = QΔV
So, since Q = 5 C and ΔV = + 20 V
W = QΔV
= 5 C × (+ 20 V)
= 100 J
Answer:
Discrete
Explanation:
There can be many kind of visible spectrum. Some of them are as follows :Infrared, Continuous
, Blackbody and Discrete.
A neon lamp produces discrete kind of visible spectrum. In this type of spectrum, the spectrum consists of different colors. It means that the neon lamp is made up of different colors or individual frequencies.
Hence, a neon lamp produces discrete visible spectrum.

you have to provide mass to get acceleration
as Newton's 2nd law, force=mass×accln
now,here force toward D is 100N,if it hav mass m
then accln will be 100/m
Break the circuit and apace a meter actually within the circuit.
