I guess the correct answer is the first one.
When silver is poured into the mould the it will solidify
In this process the phase of the Silver block will change from liquid to solid.
This phase change will lead to release in heat and this heat is known as latent heat of fusion.
The formula to find the latent heat of fusion is given as

here given that


now we can find the heat released


So it will release total heat of 55.5 kJ when it will solidify
Answer: D. They conduct thermal and electrical energy.
Explanation:
Answer:

Explanation:
To give a solution to the exercise, it is necessary to consider the concepts related to magnetic flux and Faraday's law of induction. Faraday's law states that the voltage induced in a closed circuit is directly proportional to the speed with which the magnetic flux that crosses any surface with the circuit as an edge changes over time.
It is represented under the equation,

Where,
is the induced electromotive force
N = Number of loops
= Time
= Magnetic Flux
For definition the change in magnetic flux is:

Where,
B= Magnetic field
Substituting at the first equation we have


Our values are given by,
N = 1 turn


r = 1.6mm


Replacing,


<em>Therefore the magnitud of the induced emf around a horizontal circle of tissue is
</em>
