Avery long (nearly infinite) wire is made of an insulating material. the wire carries a charge, q, which is distributed evenly along the entire length of the wire, giving it a uniform linear charge density, lambda. what is the magnitude of the electric field produced by the charged wire at a radial distance s from the wire?

E= λ/ 2πε0 with radial direction

Explanation: Using the Gaussian law, we can obtain the Electric at distance r from the line of charge very large.

In this sense

The electric flux by a closed surface is: ∫E.dS= Total charge/ε0

so

at distance r the electric field is constant and surface integral is equal to the curved surface of the cilindrical Gaussian surface  around the line of charge. It was used to conduct the Gaussian Law.

this means

A= 2πr L where L is lengt of line of charge

Finally E*2 πr L = λL/ε0

Fron this  expression the electric is: E= λ/ 2πε0

explanation:

earth's surface is mainly heated by the absorption of infrared radiation from the sun.

evaporation occurs because molecules in liquid water are warmed ( usually by the sun) and vibrate quicker, becoming less dense and rise.

condensation occurs because molecules in water vapor are cooled and therefore vibrate more slowly thus becoming more dense and eventually fall to earth.

lines of equal barometric pressure on a weather map are called: isobars : lines of equal temp on a weather map are called: isotherms.​

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
