The resistance of conductor is directly proportional to length and resistivity.

Answer: Option B

<u>Explanation: </u>

Resistance is present in an electrical object or rather introduced to counter check the flow of the current. It is similar to the mechanical friction in the conceptualization of its existence and effect.  

It is directly proportional to the length of the electric circuit. It is being measured and noted in ohm. The formula for resistance is –

                              R=\rho \frac{l}{A}

Where,

R - the Resistance of the wire,  

\rho - the resistivity of the wire  

L - The length of the wire

A - the area of cross section of the wire

If sulfur 34 undergoes alpha decay, what will I become?
ikadub [295]
It will decay into Silicon-30. Because alpha particles are 2 protons and 2 neutrons with an atomic mass of 4, you minus sulfur's atomic number by 2 and get silicon. And the atomic mass is 34 - 4 which equals 30.

A car covers 400m distance in 50 sec find it's speed?
Lena [83]

Answer:

\boxed {\boxed {\sf 8 \ m/s}}

Explanation:

Speed is equal to distance over time.

s=\frac{d}{t}

The distance is 400 meters and the time is 50 seconds.

d= 400 \ m \\t= 50 \ s

Substitute the values into the formula.

s=\frac { 400 \ m }{ 50 \ s}

Divide.

s= 8 \ m/s

The speed of the car is 8 meters per second.
