Answer: No. The ball wil not bouce back to you. A ball is similar to how light behaves because when you bounce a ball, it will go in a straight line and when it hits something, it will bouse again and go somewhere else. This is also how light behaves.

Explanation:

The ball will not bounce back to you. It will bounce again but go somewhere else similar to the way light behaves.

When a beam of light travels through a medium, it hits the particles in them.  Some of the light rays get absorbed while a few rays get scattered in various directions. The intensity of the scattered light depends on the size of the particle and its wavelength.

When light reaches matter, it can be refracted, reflected, absorbed, or scattered. Light travels in the same direction after hitting the surface is reflected light since the surface is smooth but never follows the same path.

Scattering happens when light bounces off an object or particle in a variety of directions. A ball shows behavior as light. When you bounce a ball, it follows a straight path and hits something, it will bounce again but in a different direction. That is how the light behaves.

Answer: The upper and lower mantle have very few differences but the lower mantle is more solid than the upper mantle.

Answer:

The upper and lower mantle differ from each other in location, temperature and pressure.

The upper mantle is made of melted rocks and minerals and lower mantle is made of solid rocks

Thermal energy is the average sum of all kinetic energy of all the molecules of gases. The lower the temperature of an object the lower its thermal energy.

Thermal energy is a energy which is possess by a moving object. It is directly proportional to kinetic energy of the molecules. It is very difficult to find the correct value of kinetic energy so we find average kinetic energy. Which is very easy to calculate as compared to calculating kinetic energy.

Mathematically,

K.E=2/3KT

Where,

K= Boltzmann constant

T is the temperature

Average kinetic energy is directly proportional to temperature. It is not dependent on the type of gases or mass of gases. The lower the temperature of an object the lower its thermal energy.

Therefore, the lower the temperature of an object the lower its thermal energy.

Answer: The human body contains trillions of microorganisms — dwarfing human cells by 10 to 1. Due to their little size, nonetheless, microorganisms make up just around 1 to 3 percent of the weight's (in a 200-pound grown-up, that is 2 to 6 pounds of microscopic organisms), yet assume a crucial function in human wellbeing.  In 2016, a survey of over forty years of examination into the human microbiome found that there is zero logical proof to back this frequently refered to tidbit up. Rather, the proportion appears to be about 1.3-to-1, with the normal human playing host to around 100 trillion microorganisms, plus or minus. Rather, the proportion seems to be about 1.3-to-1, with the normal human playing host to around 100 trillion organisms, plus or minus.

Explanation:

You can mix this up and paraphrase this into ur own words.

The microorganisms that are present and live in the human body are 1 to 10 micrometers.

Microorganisms are tiny living organisms that can be only seen by microscopes. These organisms are found everywhere on earth. They are free-living and parasitic. There are good and bad microorganisms.

Some are useful to the earth and the living creature, but some are harmful to the health of other living creatures. They are responsible for many diseases in plants, animals, and other organisms.

There are many bacteria present inside the body. They are present in the digestive system, and our mouth. They help in the digestion and breakdown of many food materials and macromolecules.

Thus, the size of microorganisms that are present and live in the human body is 1 to 10 micrometers.

Explanation:

The characteristics of the thermal transfer process allow to find the results for the questions regarding the temperature in the two cases are:

Thermal conduction processes are mechanical by which thermal energy (temperature) is transported, they ask to be of three types:

At the initial moment the two layers are not touching, therefore the only possible process is radiation, therefore the outermost body may be at a very high temperature and the inner body may be cold since radiation heating is the less efficient.

When the materials touch, the energy transfer process is thermal conduction, therefore the interior temperature will increase significantly. The thermal conduction process is one of the fastest, therefore the temperature rises rapidly.

In conclusion, using the characteristics of the thermal transfer process, we can find the results for the questions regarding temperature in the two cases are:

Answer: A

Explanation: Mass and volume is the amount, amount doesn’t make the phase of a matter change.

Explanation:

40 m/s2

Formula for acceleration will be:

F = m*a

Force = mass*acceleration

•

•

F = m*a

= 40 * 180 - 140 = a

1600 = a

1600/40 = a

40 = a = 40 m/s2

According to the forces of attraction, if three different samples of a liquid have different compositions, then the liquid can be classified as a mixture.

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.

During a chemical reaction, the most likely occurring is mass conservation. According to law of conservation of mass, total mass in a reaction is conserved.

According to the law of conservation of mass, the total mass in a chemical reaction or in a physical change is conserved. Simply, mass is neither created nor destroyed.

When a chemical reaction takes place,  no new atoms are created and the properties of the reactant species cannot be maintained after reaction.

Molecules of any reactant is not lost during a reaction. The total mass in the reactant side of a balanced reaction will be equal to the total mass in product side.

Therefore, the mass conservation is likely to occur during a chemical reaction. Thus, option d is correct.
