The resistance, R, to electricity of a cylindrical-shaped wire is given by the equation , where p represents the resistivity of
valentina_108 [34]

Answer:

infinity

Explanation:

Given that

Resistance = R

Resistivity = ρ

Length = L

Diameter = d

The resistance of wire R given as

R=\rho\dfrac{L}{A}

A=Area

A=\dfrac{\pi d^2}{4}

Now by putting the value of A

R=\rho\dfrac{L}{\dfrac{\pi d^2}{4}}

R=\rho\dfrac{4L}{\pi d^2}

When d tends to infinity then d² will also tends to infinity.

So when d tends to zero then the resistance tends to infinity.

Therefore answer is ---

infinity

A ladybug crawls vertically on a leaf. Its motion is shown on the following graph of vertical position y vs. time t. What is the
ella [17]

Answer: 0 m/s

Explanation: The attached figure shows the position-time graph of a ladybug. We need to find the average speed of the ladybug between t = 4 s to t = 7 s.

We know that, the slope of a position-time graph gives velocity of an object. It can be given by :

In this case, the position of a ladybug at t = 4 s and at t = 7 s is the same i.e. 2 m.

It means its velocity is equal to at this time or we can say that ladybug is at rest.
