1. The amount of toothpaste used
2. The shade of teeth before and after brushing
3. The type of toothbrush used to brush teeth
4. The size of tooth

Answers

2. The shade of teeth before and after brushing

The independent variable in this instance is the bright white toothpaste, and if they’re claiming that it removes stains better than all, then that means that the dependent variable would be the shade of teeth!

The amount of toothpaste, the type of tooth brush, and the size of tooth are all variables of the experiment but will not determine if the claim is supported or not.

What happened as the mass of the sun increased during the formation of the solar system?

Answers

Answer:

The Sun and the rest of the solar system formed from a giant, rotating cloud of gas and dust called a solar nebula about 4.5 billion years ago. Most of the material was pulled toward the center to form our Sun, which accounts for 99.8% of the mass of the entire solar system.

The increase in gravitational pull, which caused the surrounding gas and dust to be pulled towards the center of the developing solar system.

What is the Solar system?

As the mass of the sun increased during the formation of the solar system, several important changes occurred. One of the most significant changes was the increase in gravitational pull, which caused the surrounding gas and dust to be pulled towards the center of the developing solar system. As a result, the temperature and pressure at the center increased, eventually reaching a point where nuclear fusion began and the sun became a star.

The increase in mass also had an impact on the orbits of the planets. As the gravitational force of the sun increased, it caused the orbits of the planets to become more stable and circular, rather than elliptical or irregular. This stability allowed the planets to maintain their orbits over billions of years, contributing to the long-term stability of the solar system.

In addition, the increase in mass allowed the sun to retain more of the lighter elements, such as hydrogen and helium, which were abundant in the early solar system. This abundance of lighter elements contributed to the formation of the gas giant planets, such as Jupiter and Saturn, which have massive hydrogen and helium atmospheres.

Passage 1: Excerpt from Will Yellow School Buses Soon Become Rolling Ads?
1 Tight school budgets could soon translate into Missouri school districts’ selling ad space on yellow school buses.



2 Missouri state Rep. T.J. Berry, R-Kearney, says his bill—HB 224—isn’t a cure-all by any stretch. But legalizing ads inside and outside the buses would give school districts one additional way to raise money in these tough times.



3 “Every single school district has had to deal with budget concerns,” Berry said last week. “And generally speaking, the way they have had to deal with those has been cuts or tax increases.”



4 The school bus is something that is already out there and paid for, he said. His bill would permit districts to generate a modest stream of income from their buses.



5 Few question the need for finding additional funds when it comes to educating children, but at least two groups think the school bus exteriors should remain ad-free.There is no such thing as free money,” said Josh Golin, associate director for the Campaign for a Commercial Free Childhood. “There are real costs to this: the price of selling out your students to advertisers.”



7 Students don’t need the first and last message they receive from their schools each day to be advertisements, Golin said. Students boarding a bus are certainly a captive audience.



8 The National Association of State Directors of Pupil Transportation Services opposes advertising on safety grounds. Obscuring the recognizable school-bus yellow exterior with ads and distracting other drivers “present a safety problem around school buses that cannot be ignored,” the group said in its position paper.



9 National studies have shown that anything that diverts a driver’s attention from the road can pose a hazard, opponents say.



10 “And a big yellow bus doesn’t distract?” Berry asked.



11 Several years ago in Indiana, a Department of Education lawyer suggested that allowing advertisements on buses would invite First Amendment challenges by spurned advertisers, the group noted.

Which of the following is not true about sound waves.
A. Sound waves travel through medium.
B. Sound waves are invisible.
C. Sound waves can move through water.
D. Sound waves can move through a vacuum.

Answers

Answer:

D. Sound waves can move through a vacuum.

Explanation:

Sound waves can move through a vacuum is an incorrect statement.  

• Sound is a kind of energy produced by vibrations. These vibrations generate sound waves that move via the mediums like water, air, and wood.  

• The sound waves are not visible as it is a form of energy, sound waves generate movement in the object, which continues till the particles run out of energy.  

• A sound wave mediates its energy through particle interaction, and a sound wave cannot travel via a vacuum, this shows that sound is a mechanical wave.  

Thus, sound waves cannot move through a vacuum. Option A is not true.

Which statement explains why hydrogen bonds are able to form between water molecules?
Water molecules are polar.
Water molecule atoms have weak atomic bonds..
Water molecules show adhesion.
Water molecules are large.

Answers

Answer:

Water molecules are polar.

Explanation:

Hydrogen Bonds  - Opposite charges attract one another. The slight positive charges on the hydrogen atoms in a water molecule attract the slight negative charges on the oxygen atoms of other water molecules. This tiny force of attraction is called a hydrogen bond.

This bond is very weak. Hydrogen bonds are formed easily when two water molecules come close together, but are easily broken when the water molecules move apart again. They are only a small fraction of the strength of a covalent bond, but, there are a lot of them

The fact that water molecules are POLAR makes it possible for hydrogen bonds to form between them.

HOW IS WATER POLAR?

Water is a chemical compound made up of two hydrogen atoms and one oxygen atom i.e. H2O. The hydrogen atoms are electropositive while the oxygen atom is electronegative.

The electronegativity of the oxygen atom allows the positive hydrogen ions to be attracted towards it. This makes water molecules polar.

Hydrogen bonds form when hydrogen ions (H+) are attracted to an electronegative ion like 02-, S2- etc. Hence, in the interaction of water molecules, the hydrogen ion of one water molecule gets attracted to the oxygen ion of another water molecule, hence, forming HYDROGEN BOND.

In a nutshell, hydrogen bonding is possible in water due to its polariry.

What is the effect is a beam of light hits a green leaf?

Answers

You look straight at a bright, shiny object when a beam of light bounces off of it. What is the effect? All of the color beams except green are absorbed by the leaf.

Credits to johnharleyjackson

When light strikes a green leaf, most of the green spectrum is reflected and most of the other colors are absorbed.

what is light?

We can see light as a sort of energy. The sun provides some illumination. The other light is artificial. Man-made light is created by converting another type of energy, such as electricity, into light energy. From a source, light travels in a wavy beam to whatever it encounters. Each hue is represented by a tiny wavy beam on the beam. A light beam travelling through the air that contains all of the hues appears to be clear.

What is reflection?

When a light beam strikes an object, such as tree leaves or an apple, the color of the object influences the smaller color beams inside the light beam. All color rays except green are absorbed by the green leaves. Only the green beam is reflected back, thus the leaves appear green to our eyes. Except for red, the apple absorbs all color beams. Only the red beam is reflected back, thus the apple appears red to human eyes. This is referred to as reflection.
