Within the visible spectrum, our experience of red is associated with a <u>longer wavelength </u>of light.

<h3>What is the electromagnetic spectrum?</h3>

The electromagnetic spectrum is seen as colors: violet, indigo, blue, green, yellow, orange, and red. Blue light has a very short wavelength, and so produces a higher amount of energy.

In the visible spectrum, the longer wavelengths that we perceive as red are followed by intermediate wavelengths for green and shorter wavelengths for blue and violet.

Our perception of red is connected to a longer wavelength of light within the visible spectrum.

Hence longer wavelength is the correct answer for blanks.

What is the rate of acceleration due to gravity on Earth?

Katena32 [7]

Answer:

Negative 9.8 meters per second squared

Explanation:

The negative is for the direction (down, towards the center of the earth). Often this can be estimated as -10 m/s^2 to make calculations easier.

A cylindrical, 0.500-m rod has a diameter of 0.02 m. The rod is stretched to a length of 0.501 m by a force of 3000 N. What is t

Salsk061 [2.6K]

Answer:

Y = 4.775 x 10⁹ Pa = 4.775 GPa

Explanation:

First, we calculate the stress on the rod:

$stress = \frac{Force}{Area} = \frac{3000\ N}{\pi r^2} \\\\stress = \frac{3000\ N}{\pi (0.01\ m)^2}\\\\stress = 9.55\ x\ 10^6\ Pa = 9.55 MPa\\$

Now, we calculate the strain:

$strain = \frac{Change\ in Length}{Original\ Length}\\\\strain = \frac{0.501\ m - 0.5\ m}{0.5\ m}\\\\strain = 0.002\\$

Now, we will calculate the Young's Modulus (Y):

$Y = \frac{stress}{strain}\\\\Y = \frac{9.55\ x\ 10^6\ Pa}{0.002} \\$

Leya [2.2K]

Answer:

A meteor is B) an icy body with a long tail extending from it.

Explanation:

Meteors are very small dust particles that, when penetrating into the Earth's atmosphere, burn quickly by rubbing with the gases of the same. Some meteors, those with larger dimensions and appreciable weights, are brighter and can describe longer trajectories, showing longer.

In other words, the meteoroids, celestial bodies can vary in size between 100 micrometers up to 50 meters, they collide with the atmosphere of our planet and if the particles are of a small size, upon impact they enter combustion creating a flash, is what we know as meteor or shooting star. Therefore, the meteor is a luminous phenomenon that leaves behind a persistent trail.

So, <u><em>a meteor is B) an icy body with a long tail extending from it.</em></u>
