Answer:
Explanation:
boiling
According to the forces of attraction, boiling takes place when the kinetic energy of molecules overcomes the intermolecular forces.
What are forces of attraction?Forces of attraction is a force by which atoms in a molecule combine. it is basically an attractive force in nature. It can act between an ion and an atom as well.It varies for different states of matter that is solids, liquids and gases.
The forces of attraction are maximum in solids as the molecules present in solid are tightly held while it is minimum in gases as the molecules are far apart . The forces of attraction in liquids is intermediate of solids and gases.
The physical properties such as melting point, boiling point, density are all dependent on forces of attraction which exists in the substances.

Answer:
What is your body made of? Your first answer may be that it is made up of different organs like the heart, lungs, and stomach, which work together to keep it going. Or you could go even closer and say that it is made of many types of cells. However, at the most basic level, your body — and indeed, all life, like everything that is not alive — is made up of atoms, often organized into larger structures called molecules

5. Sodium-24 has a half-life of approximately 15 hours. If only one-eighth of the sodium-24 remains, about how much time has passed?
A. 15 hours
B. 30 hours
C. 45 hours
D. 60 hours
Answer:
60 hours
Explanation:
18.0 __15__ 9 __15__ 4.5 __15__ 2.25 __15__ 1.125g
15(4)= 60
Sodium-24 has a half-life of approximately 15 hours. If only one-eighth of the sodium-24 remain , then it has been passed in 60 hours. So option D is correct.
What is half life and decay law ?The time required for half of the original population of radioactive atoms to decay is called the half-life. The relationship between the half-life, T₁ ÷ 2, and the decay constant is given by T₁/2 = 0.693/λ
According to radioactive decay law, the rate of decay of radioactive atoms at any instant is directly proportional to the number of atoms present at that instant.
dtd N ∝ N
dtd N = λ N
where, N is number of integrated nucleus present in the sample at any time t and λ is decay constant.
Thus ,option D 60 hours is correct.

What are the similarities and differences between the two fish varieties?
Answer-
Fish are obviously animals because they move, they have sensory organs (eyes, mouth, barbels), and they have body structure (skeletons, skin, etc.). They breathe oxygen. They eat other organisms to survive. Fish are different from other animals because they live in water.
Answer:
The surface fish live near the surface of the water, and the blind cave fish live in dark subterranean caves. The surface fish have eyes and pigmentation on their bodies. The blind cave fish don’t have eyes, and they’re often albinos.

C. at an acute angle measuring 23 degrees
Answer:
1 closer
2 24hours
3 tidal bulges
4 in a straight line
Explanation:
Tides have been the effect of the sea with the gravitational pull of the sun and moon.
1. Earth’s tides are affected by the gravitational pull of the Sun and the Moon, but mainly the Moon because the Moon is closer to the earth.
In spite of high pull of the Sun, the distance of moon from earth results in increased effect of moon gravitational pull than Sun.
2. Each day, each coastal region on Earth experiences two high tides and two low tides in every 24 hours time period.
The daily tides has been resulted at the coast with the moon revolution around the earth's rotation.
3. This is because the gravitational attraction of the Moon creates tidal bulges on two opposite sides of the planet.
The effect of the moon gravitational force results in the bulging or the pulling force to the sea, resulting in the diurnal tides.
4. Two spring tides occur monthly, when the Moon is in its new and full phases. During these phases, the Moon and Sun are oriented at a right angle measuring 90 degrees which gravitation pulls the water on Earth in the same direction, creating a large tidal range.

The Rocky Mountains run parallel to the western coast of the United States. While parts of the California coast are lush and tropical, the area just east of the mountain range is a dry desert. What BEST explains the drastic climate difference between these two adjacent areas?
Answer:
The mountains cause rainfall.
Explanation:
The fact that the mountains run parallel to the coast is the key in the difference in climate between the two areas. Since they are parallel to the sea, they block the wind and moisture coming from the sea towards the land, the mountains cause this air to rise and when it hits the cold air at higher altitudes, it results in rain. This leads to the lush and tropical areas whereas without the parallel mountains to the coast, the amount of rain the area receives decreases, resulting in a desert like environment.

Using the enlarged metric ruler segment shown below, what is the length of the
blue line in centimeters?
Answer:
1.8 cm
Explanation:
To measure length, use a metric ruler. It is separated into centimeter-sized units. One centimeter is represented by each number on the ruler. The longest mark is the centimeter.
What is the enlarged metric ruler segment?A metric scale is used to quantify traits or variables. Interval scales, ratio scales, and absolute scales are all grouped under the phrase “metric scale.”
The majority of statistical calculations and comparisons are possible with quantitative numerical values.
To the nearest tenth of a centimeter (0.1 cm), a metric ruler, for instance, may measure length. Using a separate metric ruler, you can measure lengths to the nearest 0.05 centimeters (0.05 cm).
The measurement with the lowest degree of uncertainty (0.05 cm) is more accurate.
Therefore, 1.8 cm is the length of the blue line in centimeters.

Answer: When you turn a light on it becomes bright :)
In electrical wiring, a light switch is a switch most commonly used to operate electric lights, permanently connected equipment, or electrical outlets. Portable lamps such as table lamps may have a light switch mounted on the socket, base, or in-line with the cord. Manually operated on/off switches may be substituted by dimmer switches that allow controlling the brightness of lamps as well as turning them on or off, time-controlled switches, occupancy-sensing switches, and remotely controlled switches and dimmers. Light switches are also found in flashlights, vehicles, and other devices.
