<span>Birds which famous for performing a ritualized mating dance are: The Grebes
Grebes most commonly live near a fresh water source.
They conducted this ritual because When two Grebes with opposite sex dances near each other, they will release some sort of pheromones that make them attracted to one another. </span>
The can be found elsewhere and as follows:
<span>A. of magnetic effects.
B. the ball tries to pull the rod’s electrons over to it.
C. the rod polarizes the metal.
D. the rod and the ball have opposite charges.
</span><span>
I believe the correct answer is option C. If a negatively charged rod is held near a neutral metal ball, the ball is attracted to the rod. this happens because </span>the rod polarizes the metal. Hope this answers the question.
The concept that we need here to give a proper solution is mutual inductance.
The mutual inductance is given by the expression
Where,
I = current
N = Number of turns
Flux through the solenoid.
Part A) Then we have in our values that,
Replacing in the equation,
Part B) Here is required the Flux, then using the same expression we have that
We conserve the same value for the Inductance but now we have a current of 2.6, then
Therefore the flux in Solenoid 1 is 
Answer:
In a third class lever, the effort is located between the load and the fulcrum. ... If the fulcrum is closer to the effort, then the load will move a greater distance. A pair of tweezers, swinging a baseball bat or using your arm to lift something are examples of third class levers.
Explanation:
