Answer:

Wear and tear of soles of our shoes is due to friction.

When a tyre deflates, it is difficult to move the vehicle because of increased friction between the tyre and the road surface.

Machines get heated up and produce noise because of friction.

If a nichrome wire has a resistance of 15Ω and is connected across the terminals of a 3.0 V flashlight battery, how much current
scoray [572]

Answer:

0.20 A

Explanation:

The current in the wire is given by Ohm's law:

I=\frac{V}{R}

where

I is the current

V is the voltage

R is the resistance

In this problem,

V = 3.0 V is the voltage

R=15 \Omega is the resistance

Substituting into the formula,

I=\frac{3.0 V}{15 \Omega}=0.20 A
