Tires aren't made from pure rubber because it makes the weight higher which increases the engine load.
<h3>What is Tyre?</h3>
This is defined as a piece of rubber which is attached to the wheels of automobiles for movement.
Pure rubber isn't used to make tyres because it has a higher weight which increases the engine load thereby making the vehicle slower.

The change in surface area of Gaussian surface with radius (r) is 8πr.
<h3>
Electric field from Coulomb's law</h3>
The electric field experienced by a charge is calculated as follows;

where;
- E is the electric field
- Q is the charge
- r is the radius
The electric field reduces by a factor of 
<h3>Surface area of a Gaussian surface;</h3>
The surface area of a sphere is given as;

<h3>Change in area with r</h3>

Thus, the change in surface area of Gaussian surface with radius (r) is 8πr.

Answer:
(A) Equation will be 
(B) RMS value of voltage will be 0.530 volt
Explanation:
We have given peak to peak voltage of ac wave = 1.5 volt
Peak to peak voltage of ac wave is equal to 2 times of peak voltage
So 

Frequency of ac wave is given f = 3 kHz
So angular frequency
= 2×3.14×3000 = 18840 rad/sec
So expression of equation will be
( As phase difference is 0 )
Now we have to find the rms value of voltage
So rms voltage will be equal to
