The image below shows a loop of wire passing through a magnetic field at constant speed. which of the following statements best describes the current in the wire as the wire passes through the field

Answers

Answer 1

Answer:

Explanation:

The correct answer is:   Magnetic field lines form circles that go around the wire.

Answer 2

Answer:

C

Explanation:

Correct Answer: C. The current decreases to zero as the loop approaches the midpoint, and then changes direction and increases as the loop continues past the midpoint.

Explanation: As the wire loop approaches the midpoint, the magnetic flux through the wire is increasing. This causes a current that moves clockwise in the wire (as seen from above). After passing the midpoint, the magnetic flux is decreasing, which causes the direction of the current in the wire to reverse. The current is now counterclockwise in the wire. At the midpoint, the current is zero. The change in direction can be inferred from Faraday’s law of electromagnetic induction:

V=−ΔΦMΔt

This law states that the voltage in the wire is equal to the negative of the change in magnetic flux over time. The sign of the magnetic flux changes when the flux goes from increasing to decreasing, so the voltage and the current are reversed as well.

7) Whale flippers, bat wings, and cat legs are considered to be “homologous structures’” because they have the same skeletal parts, despite the fact that they have different functions. Remember that the prefix "homo" means the same. What do these “homologous structures” tell us about the evolution of the whale, bat and cat? *

Answers

Answer:

In simple words, Homologous structures refers to the organs or atlas device of invertebrates which recommend their connection to a common origin by virtue of their similarity. Such systems do not appear precisely the same, or have the same features.

Both bats as well as humans were primates, so both possess a shared ancestor. Both the wings of a bat as well as the hand of a person have a common internal body shape, although they appear somewhat different from the outside.

A further indication of whales possessing a sequence homology form is their ear canal bones. A whale's inner ear bones are nearly identical to terrestrial mammals however the one distinction is that they've been fused around each other.
