In solids, the atoms are closely bound to each other. The only movement possible for the atoms in this state of matter is vibration. Solids have a fixed shape. Therefore when they are put in a container, the solids remain in their initial shape.

In liquids, the atoms are loosely bound compared to atoms in solid. And the atoms are free to vibrate and to slide past each other. The liquids have fixed volume but have no fixed shape. Therefore, when they are poured into a container, their volume will be the same, but the liquid will take the shape of the container.

In gas, the atoms are very loosely bound. and the atoms are very free to vibrate and move through space. Gases do not have either fixed volume or a fixed shape. Therefore, when they are poured into a container they take the volume and the shape of the container.

A frog is at the bottom of a 17-foot well. Each time the frog leaps, it moves up 3 feet. If the frog has not reached the top of
docker41 [41]

Answer:

The frog takes 8 jumps to reach top of well

Explanation:

Given data

Frog at bottom=17 foot

Each time frog leaps 3 feet

Frog has not reached the top of the well, then the frog slides back 1 foot

To Find

Total number of leaps the frog needed to escape from well

Solution

in 1 jump distance jumped=3+(-1)

                                           =2 feet

                                           =2×1 feet

The "-1" is because the frog goes back

Now After 2 jumps the distance jumped as:

                     Distance Jumped=2+2

                     Distance Jumped=2*2

                                                   =4 feet

Similarly after 7 jumps

                    Distance Jumped=2+2+......+2

                    Distance Jumped=2*7

                                                 =14 feet

Now after 8th jump the frog climbs but doesnot slide back as it is reached to the top of well.

So

              Distance Jumped=(Distance Jumped after 7 jumps)+3

                                           =14+3

                                           =17 feet

The frog takes 8 jumps to reach top of well

What are two ways engineers use their understanding of kinetic energy and potential energy to make their designs better/ safer?
DanielleElmas [232]

Answer:

On a roller coaster, energy changes from potential to kinetic energy and back again many times over the course of a ride. Kinetic energy is energy that an object has as a result of its motion. Traditionally, the coaster cars are pulled up the first hill by a chain; as the cars climb, they gain potential energy.

Which nucleus completes the following equation?
melomori [17]

The nucleus that completes the equation given above is 218/85 At, which is option D.

<h3>What is a nuclear fission?</h3>

Nuclear fission is a nuclear reaction in which a large nucleus splits into smaller ones with the simultaneous release of energy.

According to this question, the following nuclear fission reaction is given: 222/87Fr = 4/2He+ ?

To find the missing nucleus, we subtract 4 from 222 to get 218, therefore, the nucleus that completes the equation given above is 218/85 At.

For Al, its atomic number is 13 and its mass number is 27. How many neutrons does it have? A. 13 B. 14 C. 26 D. 27 E. 40
sveta [45]

Answer:

B. 14

Explanation:

For an element:

- Atomic number: is the number of protons in the nucleus (p)

- Mass number: it is the number of protons (p) + neutrons (n) in the nucleus

For Al (aluminium), we have:

p = 13

p + n = 27

Substituting the first equation into the second one, we find the number of neutrons:

n = 27 - p = 27 - 13 = 14
