Good for her?
Explanation:
Whats the question?
Answer:
The rate at which work is done is called Power.
Explanation:
Power is work done per unit time. or it can also be defined as ratio of work done to time taken to complete the work.
Mathematically the power (P) is given as:
1 watt = 1 Joule/second
Where:
W = Work done in time T.
T = Time taken to complete the work
The rate at which work is done is called Power.
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
