An antenna emits an electromagnetic wave. The electric field lines at a certain instant in time are shown.

Three children are playing in a pool in the back yard. One child is at the far left end of the pool and is splashing. A second c

The effect that the child in the middle of the pool notices is known as <u>constructive interference. </u>

<h3>What is constructive interference?</h3>

It refers to the phenomenon where two identical waves come into contact with each other and create a new wave that is twice as amplified as their individual amplitudes.

When the waves from the friends on opposite sides reached each other in the middle, they produced more amplified waves that then raised the child in the middle of the pool higher.

Suppose a friend of yours wants to buy a crystal candlestick. You remember seeing this item at both annie's attic and betty's br

Veronika [31]

The advice that will be given in the purchase of crystal candlestick is to go to

Betty's Breakables if the price is above $25.00.

In this scenario, we were told that Betty's Breakables offers 40% discount,

while Annie Attic offers $10 discount.

<h3>Calculation</h3>

Let's assume the price is $25.00, the discount at Betty's Breakables will be

= 40/100 × $25.00

= $10.

At Annie Attic, he was offered a $10 discount which is the same. However

there will be more gain on the discount if the price is above $25.

Let's assume the price is $30 , the discount will be $12 at Betty's Breakables

which is more than that at Annie Attic in which the discount remains at $10.

It is therefore cheaper to go to Betty's Breakable if the price of the

candlestick is above $25.

List the sample space in the given experiment how many outcomes are possible brainly

Nastasia [14]

The sample space of the experiment is the elements in the set

The sample space {Head, Tail} and there are 2 outcomes in the sample space

<h3>How to determine the sample space?</h3>

From the complete question, the experiment is a toss of a coin

A coin has a head and a tail.

So, the sample space (S) is:

S= {Head, Tail}

The number of outcomes in the above sample space is 2

Hence, the sample space {Head, Tail} and there are 2 outcomes in the sample space
