The conversions are:

Electrical to electromagnetic and mechanical (when we turn on the microwave).

Electromagnetic to thermal (as the microwave heats up the cup of water).

<h3>What energy conversions occur?</h3>

We will describe the process in which you already have a cup of water inside the microwave.

First, you turn on the microwave. Here you are giving the microwave electrical energy so it can work.

The microwave rotates the cup of water, so there is a transformation of electric energy into mechanical energy.

The microwave also creates electromagnetic radiation which affects the cup, so there is a change from electric energy to electromagnetic energy.

This electromagnetic energy interacts with the water by increasing the temperature, so finally we have a change from electromagnetic energy to thermal energy.

mart [117]

Answer:

0.9726

Explanation:

The computation of the probability of a sample mean is shown below:

$P(\bar x < 24.3)$

To find the probability first we have to determine the z score which is

$z = \frac{\bar x - \mu_{\bar x}}{\sigma_{\bar x}} \\\\ = \frac{\bar x - \mu }{\frac{\sigma}{\sqrt{n} } } \\\\ = \frac{24.3 - 24}{\frac{1.25}{\sqrt{64} } }$

= 1.92

Now probability is

$P(\bar x < 24.3) \\\\= P(z < 1.92)$

= 0.9726

Hence, the probability of the sample mean is 0.9726

We simply applied the above formulas to determined the probability of a sample mean and the same is to be considered

<h3>What is symbolism?</h3>

Symbolism can be defined as a literary device which is used by an author to convey an idea, emotion or mood to his or her audience (readers), especially through the use of symbols, people, words, marks, locations to represent it.

<h3>The tragedy of Julius Caesar.</h3>

In this scenario, the excerpt was taken from a literary work titled "The tragedy of Julius Caesar" about a nightmare by Calpurnia with respect to the bleeding statue of Caesar.

Based on the given excerpt, we can deduce that the bleeding statue is a positive symbol that suggests Caesar will nourish Rome and be successful.
