Answer:

Energy can change form, but the total amount of energy stays the same.

Explanation:

Energy transformation diagrams shows the different forms of energy which are converted into different forms.

As we know by an example of potential energy to kinetic energy conservation when a block is compressed against the spring then initially total energy is in the form of elastic potential energy of the spring.

When block is released then total potential energy of the block is converted into the kinetic energy of the block.

So here we know that in energy transfer diagram shows the transformation of energy while total energy will always remains conserved.

so here correct answer would be

Energy can change form, but the total amount of energy stays the same.

A. Write two or three sentences to describe the conductivity of an insulator. Explain its conductivity in terms of the electrons

aliya0001 [1]

PART A)

Conductivity of insulator is very small as there is no free electrons to conduct the current trough that medium

So here number of conduction electrons are very less in insulators

PART B)

Resistance is the property of a conducting medium which will oppose the flow of current trough it

Resistance of wire directly depends on its length so resistance of long wire will be more than the resistance of short wire

Resistance inversely depends on the area so if a wire has more crossectional area then its resistance must be small

PART C)

power of light bulb is defined as rate of electrical energy

it is given by formula

P = i V

here we know that

i = 1.46 A

V = 120 volts

so power is given as

$P = 1.46 \times 120$

$P = 175.2 Watt$
