Answer:

the hot bulb will have high resistance to the flow of current. While the cold bulb will have a low resistance to the flow of current.

Explanation:

A conductor that does not obey Ohm's law is described as non - ohmic. An example is a filament lamp. It glows as the current passes through it.

How does the resistance of the light bulbs differ when the bulbs are cold and when the bulbs are hot ?

The resistance of the light bulbs increase gradually as its temperature is increased.

So, the hot bulb will have high resistance to the flow of current. While the cold bulb will have a low resistance to the flow of current.

Because the resistance of an impure metal wire is greater than the resistance of a pure metal wire of the same dimension.

The total energy of the Pendulum-Earth system is equal to 1.54416 Joules.

<u>Given the following data:</u>

Mass = 0.3 kg

Height = 0.26 meter.

Velocity = 2.28 m/s.

<u>Scientific data:</u>

Acceleration due to gravity on Earth = 9.8 $m/s^2$

To calculate the total energy of the Pendulum-Earth system:

<h3>How to calculate total energy.</h3>

The total energy possessed by this Pendulum-Earth system is equal to the sum of both the potential energy and kinetic energy at its lowest point.

Mathematically, the total energy is given by this formula:

$E = mgh + \frac{1}{2} mv^2$

Substituting the given parameters into the formula, we have;

$E = 0.3 \times 9.8 \times 0.26 + \frac{1}{2}\times 0.3 \times 2.28^2\\\\E=0.7644+0.77976$

E = 1.54416 Joules.
