The longest wavelength within the visible spectrum is _______ light. A. blue
B. orange
C. red
D. violet

Answers

Answer 1
Answer: The longest wavelength within the visible spectrum is the redlight. The answer is letter C. It is called visible light because it is theonly light that can be seen by the human eye. Red light is the longestwavelength around 620 to 750 nanometer. It is followed by orange which has awavelength of 590 t 620 nanometer. And then blue which has a wavelength of 450to 495 nanometer. And the shortest wavelength is violet which has a wavelengthof 380 to 459 nanometer.  
Answer 2
Answer:

The longest wavelength within the visible spectrum is red light. The correct option is C.

The visible spectrum of light consists of different colors ranging from red to violet. Each color corresponds to a different wavelength. Among the given options, red light has the longest wavelength within the visible spectrum.

A. blue: Blue light has a shorter wavelength compared to red light. It is located on the shorter end of the visible spectrum.

B. orange: Orange light has a shorter wavelength compared to red light. It falls between red and yellow on the visible spectrum.

C. red: Red light has the longest wavelength among the visible colors. It is located on the longer end of the visible spectrum.

D. violet: Violet light has a shorter wavelength compared to red light. It is located on the shorter end of the visible spectrum, just after blue.

Therefore, the correct option is C. red as it has the longest wavelength within the visible spectrum.

Which of the following states of matter is always a good conductor of electricity? solid, liquid, gas, or plasma **:/ Thank you!

Answers

Plasma...I believe is always a good conductor of electricity. I was tempted to say a solid, but not all solids are the same in composition and that goes for liquid and gas as well.

Hopefully this helped and good luck.

A 10-meter long ramp has a mechanical advantage of 5. What is the height of the ramp?

Answers

1.       If the ramp has a length of 10 and has a mechanical advantage (MA) of 5. Then we need to find the height of the ramp.
Formula:
MA = L / H
Since we already have the mechanical advantage and length, this time we need to find the height .
MA 5 = 10 / h
h = 10 / 5
h = 2 meters

Therefore, the ramp has a length of 10 meters, a height of 2 meters with a mechanical advantage of 5.



Answer:

height=2

Explanation:

MA= input/output

MA= 5

input = 10 (the ramp)

output=x (the height)

5=10/x

x=2

A particle moves in a straight line with constant speed of 4 m/s for 2 s, then with 6 m/s for 3 s. The average speed of the particle in the given time interval be v. Find [v].(where, [ ] is step integer function)

Answers

Answer:

Explanation

Total time, T=2+3=5 s

Total distance, D=4×2+6×3=26 m

Thus, average speed=D/T=26/5=5.2

Thus, [x]=5

What are the basics of physics.I want to learn them for an exam?

Answers

If it were possible to give that information over in a few paragraphs or a few mimutes, then you'd see little stores everywhere, where you could drop in for an hour or an afternoon, pay a few bucks, and learn Physics. You don't, because you can't, because it isn't. Here are a few things you definitely need. But I have to tell you: If you don't put time and effort into learning them, they won't do you much good. ==> F=m a. ==> Total mass is conserved. ==> Total energy is conserved. ==> Everything falls at the same rate. ==> Sound needs material to travel through. Light doesn't. ==> Light, radio, heat, X-rays, and ultraviolet radiation are all the same thing. ==> It takes force on an object to make it speed up, slow down, or curve. A moving object with no force acting on it keeps going in a straight line at the same speed forever. ==> Gravity attracts every speck of mass in the universe to every other speck. The forces of attraction are greater when the masses are greater and closer together.
one cannot simply give the basics of physics.

.Please explain to me how to find the momentum

Answers

Answer:

momentum = mass x velocity

Explanation:

So ultimately, find the mass of the object (be careful since this is not the same as weight. Weight is your gravitational pull to the earth. This means that your weight different amounts on different planets. But mass stays the same on all planets, it's what most people call their weight.) and then find the velocity (2 meters/second north, etc.)

Now you can apply this to your problem

An insect is able to walk across the surface of a pond without sinking because of the A. polarity of the water molecules.
B. process of evaporation.
C. surface tension of the water.
D. adhesion of the insect's feet to the surface of the water.

Answers

C. surface tension of the water.
the answer to that will be D because it has nothing at all to do with the water because either way the water shall stay the same if the animal or insect could or could not be able to walk on water.
