Answer:
do we have to choose 2 answers here?
<u>Explanation</u>:
Resistivity of silver wire =
Resistivity of copper wire = 
Resistance = Resistivity *length/cross sectional area
So,
For E calculation
For copper
E = resistivity * current density
E = Resistivity * current/area
For silver
Potential difference 
For silver
Potential difference = 
For copper
Potential difference =
Answer:
the answer is the second one
Explanation:
the person is moving through the air while the other people are either not moving forward or backwards or on the ground with full controll over where they go
Internal thermal energy will depends upon its temperature
so here the temperature range will be maximum 1000 degree C
so here maximum thermal energy is given by
<em>A Nuclear Reactor Core</em>
So here the maximum thermal energy and have the most heat flow is given by nuclear reactor core as it has maximum temperature
We are to solve for the net electric field (E) given that there were two electrical charges at point A and B. The given values are the following:
Ea (at point A) = 7.1 x 10^5 newtons/coulomb
Eb (at point B) =2.2 x 10^5 newtons/coulomb
Solving for the net charge, we have:
E = Ea + Eb
E = 7.1x10^5 + 2.2 x10^5
E = 9.3 x 10^5 Newtons/Coulomb
The net electric field is 9.3 x10^5 Newtons/Coulombs.
