Which is an example of something heated by conduction
hodyreva [135]
An example would be a pot on a stove. The radiation from the source of the heat (the stove) would make the handle hot by conduction from heat through contact.

Another example could be a metal spoon in a hot cup of coffee. The coffee itself is hot, but since the spoon is in the coffee and making contact, part of the spoon will become hot from the radiation of the source of heat (the hot coffee). Thus, conduction.

A thin ball shell is shaped like a hollow ball with a radius of 42.8 cm. The material is a conductor with charge 0.8 nC A point
Gala2k [10]

Answer:

The Electric field will be 225.92 N/C

Explanation:

Given :

  • Radius of the hollow sphere R=42.8 cm
  • Initial charge on the conducting sphere is Q_1=0.8\times10^{-9}\ \rm C
  • Magnitude of the point charge q_2=-5.4\times10^{-9}\ \rm C

We know that the flux of the electric field through a close surface cab be calculated by using Gauss Law which is

\int EdA=\dfrac{Q_{in}}{\epsilon_0}\\\\E\times4\pi\times 0.428^2=\dfrac{(0.8-5.4)\times10^{-9}}{\epsilon_0}\\\\E=225.92\ \rm N/C

Hence the Electric Field is calculated.

The answer founded out by you seems to be correct and very close to the exact answer and the concept you have used in your answer is also correct.
