When astronomers use an optical telescope to look at the center of our Milky Way galaxy, it is difficult to see through all the dust and gas. However, with the use of other waves in the electromagnetic spectrum they are able to pick up detail, such as protostars and remnants of supernovas. Which wave is used when studying temperature differences?


A) Radio Waves

B) Infrared Waves

C) Microwaves

D) Gamma Waves

Answers

Answer 1
B because A is for radios of course and C is thermal energy and D is radioactive
Answer 2

A yellow ball with a mass of 2 kg is rolling across the floor at 3 m/s. A red ball with a mass of 3 kg is rolling across the same floor at 3 m/s. Which ball has greater kinetic energy, and why?

plz hurry in the test nowwwwww!!!!!!

Answers

Answer:

In order to determine which ball has a higher kinetic energy, we first look at the formula of kinetic energy which is:

kinetic energy = 1/2 * mass * velocity²

The factors influencing the kinetic energy of an object are its mass and its velocity. Both of the balls have the same velocity; however, the red ball has a greater mass. Therefore,

The red ball has greater kinetic energy, because it has a greater mass.

We may also determine these quantitatively using the formula given and the kinetic energy of the yellow ball works out to be 9 J and that of the red ball is 13.5 J.

If there is less ionization energy does that mean that it is more reactive? Why?

Answers

Answer:

The greater the ionization energy, the more difficult it is to remove an electron. The ionization energy may be an indicator of the reactivity of an element. Elements with a low ionization energy tend to be reducing agents and form cations, which in turn combine with anions to form salts.

To remove that tarnish from the ring, students placed it in a pan lined with aluminum foil and added hot water. Baking soda was added to the hot water and stirred. Students made observations about the process. Which observation of this process provides evidence of a chemical reaction? *
A- Hot water heated the aluminum foil
B- The liquid solution changed color
C- The pan was lined with aluminum foil
D- The hot water cooled

Answers

Answer: B

Explaination:  The liquid solution changed color means is turned into a different substance with different properties. It is chemical change .

Liquid solution changed color provides an evidence of  a chemical reaction as it is accompanied by a chemical change.

What is a chemical change?

Chemical changes are defined as changes which occur when a substance combines with another substance to form a new substance.Alternatively, when a substance breaks down or decomposes to give new substances it is also considered to be a chemical change.

There are several characteristics of chemical changes like change in color, change in state , change in odor and change in composition . During chemical change there is also formation of precipitate an insoluble mass of substance or even evolution of gases.

There are three types of chemical changes:

1) inorganic changes

2)organic changes

3) biochemical changes

During chemical changes atoms are rearranged and changes are accompanied by an energy change as new substances are formed.

In your own words describe some properties of energy.

Law of conservation of matter: It is the principle that matter can not be destroyed or created and we have a finite and limit amount of matter in the universe.

Answer:

In explanation, these are the some I can think of that are basic.

Explanation:

Potential energy- Is an energy that is stored in something, like elastic. When you stretch it, you are creating potential energy.

Kinetic energy- Is an energy where something is being in motion. Like a roller coster, when you are being plunged to the bottom, you are witnessing kinetic energy!

Electrical energy- Is an energy which has to do with electric charge, like for example take a light bulb, and when you are putting it into it's place and it turns on, that is electrical energy flowing into the light bulb to turn it on.

Elastic energy- Is an energy where is you stretch elastic, you are creating energy that is compressed, and then letting it go.

This is a lot, but there are more basic ones, but I just went with the ones I thought were easy. I hope this will help you! Sorry if it doesn't help at all.

1.What are two factors that are necessary for hurricane development?

2.What kind of weather occurs after a cold front passes through an area?

3.What kind of weather occurs after a warm front passes through an area?

Answers

Answer:

1. tropical storms and hurricanes

2.After a cold front moves through your area, you may notice that the temperature is cooler, the rain has stopped, and the cumulus clouds are replaced by stratus and stratocumulus clouds or clear skies.

3.Warm fronts often bring stormy weather as the warm air mass at the surface rises above the cool air mass, making clouds and storms. Warm fronts move more slowly than cold fronts because it is more difficult for the warm air to push the cold, dense air across the Earth's surface.

Explain how the models you developed show that when methane combines with oxygen to form carbon dioxide and water, no atoms are left over from the reaction.

Answers

Answer: the bonds in the methane and oxygen come apart, the atoms rearrange and then re-bond to form water and carbon dioxide

Explanation:^

From the law of conservation the reactant and product will be always same, that is no atom is extra added or no atom is left over.

What is law of conservation?

The Law of Conservation of Mass basically states that matter can neither be created nor destroyed.

From the reaction, we can see that left hand side are reactant and right hand side is products. In left side 1 carbon, 4 hydrogen, and 4 oxygen. Right hand side 1 carbon, 4 oxygen, 4 hydrogen.

Mathematically, we can say that- LHS = RHS
