A.) An Iron horseshoe
B.) An aluminum rod
C.) A copper wire carrying current
D.) A positively charged glass rod
E.) A copper wire not carrying any current
F.) Another magnet
Answer:
A.) An Iron horseshoe
C.) A copper wire carrying current
F.) Another magnet
Explanation:
As we know that two magnets and two different magnetic materials will attract or repel each other
This is due to interaction of two materials due to which their magnetic field interacts and apply force on each other
Here we know that
magnetic field due to current carrying wire is given as
so here the magnetic fields will interact when a current carrying wire is placed near the magnet, or another magnet is placed near the magnet or any magnetic material like iron horse shoe is near it

The carpet is more likely to accumulate excess electric charge (static electricity) over time when there is no good way for it discharge. The dry air, as was said, insulates the carpet and makes it prone to such accumulation. This is less the case with humid air that allows the carpet to continuously discharge a portion of its electric charge over time and thus spares us--the walkers--a minor shock.
Dry air is a better electrical conductor than humid air, which is why you are more likely to receive a shock after walking across a carpet when the air is dry compared to when the air is humid.
The reason you are more likely to receive a shock after walking across a carpet when the air is dry than when the air is humid is because dry air is a better electrical conductor than humid air. When the air is dry, it has a lower field strength, meaning that it takes a smaller voltage to create a spark. On the other hand, humid air breaks down at a lower field strength, so it takes a larger voltage to create a spark. This is why you are more likely to get a shock on a dry day.

The speed of the pendulum is greatest at the midpoint of the pendulum marked 3.
A pendulum is an device that can be used to demonstrate oscillation. We know that in pendulum the potential energy is maximum at the ends of the pendulum.
Thus, the speed of the pendulum is greatest at the midpoint of the pendulum marked 3.
