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.

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.

Joel claims that “Bright White Toothpaste” removes tooth enamel stains better than all other brands. Which of the following should be documented as evidence to support his claim?
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 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.

A chimpanzee and a pine tree have very little in common. However, because they are both living things, we can be certain that they both -use the sunlight to make their own food.travel with other members of their species.are made up of one or more cells.have a skeleton which allows them to move.

Answers

Answer: C. Are made up of one or more cells

Explanation: Good luck! :D

A chimpanzee and a pine tree have very little in common because they are both living things, and made up of one or more cells that is the first and third option, as they are both living forms of nature, and while the chimp is movable, the pine tree is not.

What is the significance of the animals and plants?

The significance of animals and plants is that both have unique characteristics and equal importance in nature, such as the plants' ability to produce food through the process of photosynthesis and the animals' ability to keep the system clean, such as when some animals help in plant fertilization, maintain the carbon and oxygen cycles, and so on.
