As we know by Gauss's law that

\int E.dA = \frac{q}{\epsilon_0}

so for line charge the gaussian surface is cylindrical in shape

so we will have

E(2\pi RL) = \frac{\lambda L}{\epsilon_0}

now by rearranging the terms

E = \frac{\lambda}{2\pi \epsilon_0 R}

so here we will have to find the x component of electric field so it is given by above equation

E_x = \frac{\lambda}{2\pi \epsilon_0 x}

here x = distance from the wire where we need to find electric field

Sauron [17]
Hi,

The force that acts on hydraulic machine is heavy therefore the content must be something that cannot be compressed by that kind of force, the gas can easily be compressed while a liquid is nearly impossible to.

A block of mass m = 4.8 kg slides from left to right across a frictionless surface with a speed Vi=7.3m/s. It collides with a bl
nirvana33 [79]

Answer:

The speed of the 11.5kg block after the collision is V≅4.1 m/s

Explanation:

ma= 4.8 kg

va1= 7.3 m/s

va2= - 2.5 m/s

mb= 11.5 kg

vb1= 0 m/s

vb2= ?

vb2= ( ma*va1 - ma*va2) / mb

vb2= 4.09 m/s ≅ 4.1 m/s

A car traveling at a speed of 50.0 m/s encounters an emergency and comes to a complete stop. How much time will it take for the
ludmilkaskok [199]

Answer:

t=1.25s

Explanation:

The formula is

a= (V1-V0) /t

t = (V1-V0)/a

V1=50m/s

V0= 0 m/s

a= - 4m/s2

t= (0-50)/-4 = 1.25s

What is a good topic sentence when writing about what happens to your body if you drink a Coke ?
Romashka-Z-Leto [24]
Based on research by health writer Wade Meredith, it explains that a 330ml can of Coca Cola contains so much sugar, your body should vomit - but the phosphoric acid "cuts the flavor", helping you keep the liquid down.

After 40 minutes, your blood sugar has spiked, your pupils dilated, and your blood pressure has risen.

• Here's what to drink to be healthy

The body starts to produce more dopamine, a neurotransmitter that controls the brain's pleasure centres - "physically the same way heroin works, by the way".
