Which best describes nuclear energy?

svet-max [94.6K]

Answer:

The correct answer is - D. the energy stored inside the center of an atom.

Explanation:

Each atom has a small center in it called the nucleus and the energy that holds the nucleus or center of the atom together in the atom is known as nuclear energy.

It is the energy that is stored in the center of the atom and normally does not come out, however, in some radioactive atoms the sends some part of the energy as radiation.

Thus, the correct answer is - D. the energy stored inside the center of an atom.

Which type of force occurs between two objects at a distance?

agasfer [191]

Answer:

Gravitational force of attraction.

Explanation:

When two bodies of masses 'm' and 'M' are separated by a distance 'r', then both the bodies experience a force of attraction towards each other. This force of attraction is called gravitational force. It is a weak force but it always act between two bodies that have mass.

The magnitude of the gravitational force is directly proportional to product of the masses and inversely proportional to the square of the distance between the masses.

This means that as the distance between the bodies is increases, the gravitational force between the bodies decreases and vice versa.

The gravitational force of attraction is given as:

$F_g=\frac{GmM}{r^2}\\\\G\to \textrm{Universal Gravitational constant}$

Calculate the number of Carbon atoms in 1.50g of C6H12O6

Whitepunk [10]

Answer:

3.01 ·10↑22

Explanation:

First you want to convert the grams of Glucose to moles of Glucose.

$\frac{1.5 grams of glucose}{180.15588grams/molesglucose} =.008326 Moles of Glucose$

Next find the formula units of glucose.

.008326Moles of Glucose · 6.022 · 10↑23Forumula Units*Moles↑-1 =

5.01 ·10↑21 Formula Units of Glucose

Now multiply the formula units of glucose by the amount of each element in the molecule.

So for Carbon:

6carbon · 5.01 · 10↑21 = 3.01 · 10↑22
