The speedometer of a car reveals information about the instantaneous speed of your car.
It shows your speed at a particular instance in time...
Yet, on average, you were moving with a speed of 25 miles per hour.

Hope you liked the example, and glad I could help!

Answer:

Yes average speed may be different from instantaneous speed

Explanation:

When an object is moving with non uniform speed on a straight road or on a curved path then its instantaneous speed at different points of its path is different.

But if we will find the average speed of the path then it will be different from its actual average speed

For example we can say that let a Car is moving for speed 40 km/h for first hour of its journey and then for next hour of its journey its speed is 60 km/h

So here instantaneous speed of the car is either 40 km/h or 60 km/h

While to find the average speed we will say

$v_{avg} = \frac{v_1 + v_2}{2}$

$v_{avg} = \frac{40 + 60}{2} = 50 km/h$

Electric field strength = resistivity of copper x current density
where
p= 1.72 x 10^-8 <span>ohm meter
diameter = 2.05mm=.00205 m
current = 2.75 A
</span>get first the current density:
current density = current/ cross section area
find the cross section area
cross section area = pi.(d/2)^2;
cross section = 3.3 006x10-6 m^2
substitute the values
current density = 2.75A/3.3006x 10-6m^2
current density=35.55 x1 0^2 A/m^2
Electric field stregnth =1.72 x 10^-8 ohm meter x 35.55 x10^2 A/m^2
Electric field stregnth= 46.415 Volts/m

The electric field strength of copper is 46.415 V/m.
