I HOPE THIS HELPS!!!

So, what is a force? A force is a push or a pull exerted on one object from another. Forces make things move. You can make something start or stop when you push or pull an object.

There are many different types of forces in action in football. A player kicking a football is a force that makes the football fly through the air. A quarterback throwing a football is another example of a force that makes the football fly in a game.

When studying the concept of force, we can look to history to find mathematical principles that guide the laws of motion. Sir Isaac Newton was one of the most famous scientists of the 17th century to study the laws of forces and motion. Through careful study of how objects react to various forces, Newton developed the Three Laws of Motion. Below are explanations of each law and how these laws can be applied to football.

What voltage would be measured across the 15 ohm resistor?

Alona [7]

Answer: That depends on what other components are in the same circuit

along with the 15-ohm resistor.

If there's nothing else, and the battery is connected across the 15-ohm

resistor, then when you measure the voltage across the 15-ohm resistor,

your voltmeter is also connected straight across the battery, and you read

10 volts.

A mole is defined as the number of atoms in an exact mass of which isotope?

alisha [4.7K]

Answer:

Isotope of carbon-12.

Explanation:

The MOLE is a unit of measurement of the amount of a pure substance which contains exactly the same number of chemical units which could be (Atoms, molecules etc.) posses atoms in exactly $12$ grams of isotope of carbon-12 (i.e., $6.022\times 10^{23}$ ).

So, The mole is the Notation used for an amount $6.022\times 10^{23}$ as same the 12 number is used for dozen for making count of Bananas and many more.

The $6.022\times 10^{23}$ is known as the fundamental constant names Avogadro's number ( $N_{A}$ ), It is in the honor of Italian scientist Amedeo Avogadro.

Will mark Brainliest!!

Ilya [14]

Answer: 600 m

Explanation:

Speed $V$ is defined as the distance traveled $d$ in a especific time $t$ :

$V=\frac{d}{t}$

Where:

$V=343 m/s \approx 300 m/s$ is the speed of sound

$t=2 s$ the time you hear the thunder after you see the flash of lightning

We need to find the distance at which you are from the lightning strike:

$300 m/s=\frac{d}{2 s}$

Finding $d$ :

$d=(300 m/s)(2 s)$

Finally:

$d=600 m$
