Answer:
C. Tension
Explanation:
The tension in the cord occurs because of the muscle power of Daryl, who lifts the brick. While doing so, Daryl needs to overcome the gravitational pull on the brick.
EXTRA:
If the brick was much heavier, than Daryl's muscles would not be able to overcome the the gravitational pull on that brick, and then the much heavier brick would remain stationary on the ground, despite the efforts made by Daryl.
The phenomenon that is occurring is depicted in fig. Induction can be used to provide an explanation for this. As seen in Fig., when a negatively charged plastic rod is pushed close to a metal rod that is initially unaltered, the metal rod's left end picks up positive charges while the right end will pick up negative charges as a result of induction. when the empty metal ball is brought close to the metal rod's right end. The ball's near face subsequently develops a positive charge as a result of induction, and this positive charge attracts the rod since opposite charges are attracted to one another.
<h3>
Define Induction?</h3>
Electromagnetic induction, often known as induction, is the technique of creating electrical current in a conductor by exposing the conductor to a fluctuating magnetic field. Because the magnetic field is thought to have induced the current in the conductor, it is known as induction.

Working of a Half wave rectifier
The diode is connected in series with the secondary of the transformer and the load resistance RL. The primary of the transformer is being connected to the ac supply mains. The ac voltage across the secondary winding changes polarities after every half cycle of the input wave.
