Answer:
1) in metal object heat transfer through the conduction .In vacuum heat transfer through only radiation .
In only gaseous state or in liquid state the heat transfer through convection hence option D is correct
Answer:
The electric field is zero inside the metal sphere
Explanation:
Gauss's law says: the net flow on any enclosed surface is equal to the value of the charge inside divided by the electrical permittivity
E = Q / ε
Where Q is thec charge into the surface.
If we apply this to the metal sphere, all the charge is on the surface, so there is no charge inside, therefore, the electric field is zero
Answer:
<h2><u>✍</u><u> </u><u>What is quantum physics?</u></h2>
- ➳ It's the physics that explains how everything works; the best description we have of the nature of the particles that make up matter and the forces with which they interact.
- Quantum physics underlies how atoms work, and so why chemistry and biology work as they do.
Answer:
Explanation:
As per Faraday's law of Electromagnetic induction we know that
Rate of change in magnetic flux will induce EMF in the closed conducting loop
so we have
now we have
now we have
now the induced EMF through this loop is given as
