Answer:
E.true only when no charge is enclosed within the Gaussian surface.
Explanation:
Because Gauss’s law states that the net flux of an electric field in a closed surface is directly proportional to the enclosed electric charge.
when brakes are applied then the tyres are stopped by brake- shoe
these brake shoe are rubber grip which hold tight at the rim of tyre
when these brake show hold tight at the rim then it will apply normal force on the tyre
Due to the rough surface of rubber and rim of the tyre these two surface apply force of friction on these two surfaces
Due to this friction force it resist the motion of tyre and due to which tyre will stop.
So the main cause to stop the tyre will be FRICTION force between brake shoe and tyre rim
Answer:
Carbon dioxide (CO2)
Explanation:
Carbon dioxide (CO2) makes up the vast majority of greenhouse gas emissions from the sector, but smaller amounts of methane (CH4) and nitrous oxide (N2O) are also emitted. These gases are released during the combustion of fossil fuels, such as coal, oil, and natural gas, to produce electricity.
Answer:
50,000 V/m
Explanation:
The electric field between two charged metal plates is uniform.
The relationship between potential difference and electric field strength for a uniform field is given by the equation

where
is the potential difference
E is the magnitude of the electric field
d is the distance between the plates
In this problem, we have:
is the potential difference between the plates
d = 15 mm = 0.015 m is the distance between the plates
Therefore, rearranging the equation we find the strength of the electric field:
