Answer:
V1 = 15m/s[45o E of N.] = 45o N. of E.
V2 = 18m/s[5o N. of E.].
Vr = 15m/s[45o] + 18m/s[5o].
Vr = 15*Cos45+15*sin45 + 18*Cos5+18*sin5.
Vr = (10.61+10.61i) + (17.93+1.57i) = 28.54 + 12.18i.
Magnitude = sqrt(28.54^2 + 12.18^2) =
Tan A = Y/X = 12.18/28.54 = 0.42887. A =

Solar system coalesced out of a swirling cloud of interstellar dust/gas is known as nebula gas theory
According to nebula gas theory, the Sun and all the planets of our Solar System began as a giant cloud of molecular gas and dust called solar nebula. Then, about 4.57 billion years ago, something happened that caused the cloud to collapse.
A shock wave from a nearby supernova explosion probably initiated the collapse of the solar nebula. The Sun formed in the center, and the planets formed in a thin disk orbiting around it.
Nebular Hypothesis: a widely accepted model. Originally formulated in 1755 by a German Philosopher Immanuel Kan. Its subsequent development has interwoven a variety of scientific disciplines including astronomy, physics, geology, and planetary science. The solar system coalesced out of a swirling cloud of interstellar dust/gas called nebula. Sun born from a nuclear reaction called nebula.

The reversing of the magnet polarity will explain the different current reading.
Answer: Option D
<u>Explanation:</u>
According to Faraday's law of inductance, whenever a bar magnet is moved toward a stationary coil at constant speed, current will be generated in that coil. So in this case, the first maximum current in the above situation say A is recorded successfully.
Similarly, when the arrangement is kept as it is, in situation B, the current is observed to have different reading. This may be because of the polarity of the magnet would have changed leading to different current reading.
