Answers

Answer 1
Answer: The Answer is C. Solar Flares
Answer 2
Answer: Solar Flares. solar flares are a certain eruption of magnetic energy on or near the surface of the sun, usually associated with sunspots and accompanied by bursts of electromagnetic radiation and particles ultraviolet and x-ray radiation from sun flares often induce electromagnetic disturbances in the earth's atmosphere.

This experiment is to see if water flows faster out of a smaller can or a larger can. You will need:

• two cans (one quite small like a soup can and the other large, like a juice, can.)

Follow these steps:

A. Remove the top of each can. Punch a hole in the side of each can, very close to the bottom, making sure the holes are equal in size. Cover each hole with a piece of tape, and place the cans next to the sink.
B. Put water in both cans, making sure the water is at the same level - different amounts, but the same level. Turn the cans so the holes are facing into the sink, and remove the tape at the same time. Answer these questions: Do the streams of water shoot out at the same distance? Why or why not?
C. Try the same experiment, but this time put one cup of water in each can. What happens to the streams of water now?
D. Try the same experiment, but this time fill both cans to the top. What happens to the streams of water?



ANSWER A B C AND D CORRECTLY!!!

Answers

the water flows faster out of a smaller can than it does a larger can.

Answer:

A&B: The stem of the water does not shoot out the same distance because one can have less water and the other can have more water and the can with less water have more pressure that making the can shoot out further than the can with more water.

C: Less water will come out of the two cans because they are compressed together so all of the water is trying to come out all at the same time.

D:All of the water in the can started coming out all in one small stream.

Explain type of inertia​

Answers

Inertia is the tendency of an object to resist changes in its state of rest or motion. Different types of inertia are: 1. The inertia of Rest: The inability of a body to change by itself its state of rest is called inertia of rest. Example: A person sitting in a car falls backwards when the car starts.

Inertia of Motion: The Inability of a body to change by itself its state of uniform motion is known as Inertia of motion.

What is an example of a light mediem wave.

Answers

Speed of light is an example of a light medium wave.

Most famous Michelson-Morley (1887) demonstrated that light travels at the same speed regardless  of whether it was measured in the direction of the Earth's motion or at right angles to it. When the light travels through a vacuum: It moves from medium to medium (example: air to glass) speed can change depending of the new medium's index of refraction and the "bending" of light is essentially how lenses work.
Hey there

An example of a light medium wave is Speed of light. 

True or false? Pluto is less than 2/3 the size of Earth's moon?

Answers

Pluto has 66% of the diameter of the Earth's moon and 18% of its mass.

So your answer is true

Hope I Helped You!!! :-)

Have A Wonderful Day!!! :-)
This is a math problem. To solve this we create a ratio of the radius of Pluto to the Moon.

(737)/(1079) showing that Pluto is about 68% the size of the moon. You asked if Pluto was less than (2)/(3) or 66%, or less the size of the moon.

68>66 so the answer is False if you are talking about the volume or size of the two.

If you are talking about density, the ratio would be:

(1.88)/(3.34) which equals 56% so the answer would be True if you are inquiring about density.

Did that answer your question?
