Correct answer choice is :

B) Red, orange, yellow, green, blue, indigo, and violet

Explanation:

A spectral color is a color that is extracted in a natural human by a single wavelength of light in the apparent rainbow, or by a comparatively narrow band of wavelengths, also recognized as monochromatic light. The combination of colors provided when the light is separated by a prism. Spectrum an indexed order of the elements of an radiation or wave. Electromagnetic rainbow the complete wavelength spectrum of electromagnetic waves.

The correct answer to this question is- B) Red, orange, yellow, green, blue, indigo, and violet.

EXPLANATION:

The visible region of the electromagnetic spectrum consists of white light with its constituent seven colors.

The constituent colors are known as violet, indigo, blue, green, yellow, orange and red respectively.

As per electromagnetic spectrum, these colors of light lie in the wavelength region ranging from 350 nm to 700 nm.

The wavelength of violet light is minimum, and is maximum for red light.

If we arrange these seven colors in the descending order of their wavelength, then they are arranged as follows-

Red > Orange > Yellow > Green > Blue > Indigo > Violet.

Hence, the perfect order is option B .

If you push a bowling ball and a golf ball with an equal force what will happen

Answer:

Explanation:

Larger than the force used to push the object that has less mass. A golf ball and a bowling ball are moving at the same velocity. When gravity and air resistance are equal, the object has drawn its terminal velocity.

A spring with spring constant 15 N/m hangs from the ceiling. A ball is attached to the spring and allowed to come to rest. It is

olga nikolaevna [1]

Explanation:

It is given that,

Spring constant of the spring, k = 15 N/m

Amplitude of the oscillation, A = 7.5 cm = 0.075 m

Number of oscillations, N = 31

Time, t = 15 s

(a) Let m is the mass of the ball. The frequency of oscillation of the spring is given by :

$f=\dfrac{1}{2\pi}\sqrt{\dfrac{k}{m}}$

Total number of oscillation per unit time is called frequency of oscillation. Here, $f=\dfrac{31}{15}=2.06\ Hz$

$m=\dfrac{k}{4\pi^2f^2}$

$m=\dfrac{15}{4\pi^2\times 2.06^2}$

m = 0.0895 kg

m = 89 g

(b) The maximum speed of the ball that is given by :

$v_{max}=A\times \omega$

$v_{max}=A\times 2\pi f$

$v_{max}=0.075\times 2\pi \times 2.06$

$v_{max}=0.970\ m/s$

$v_{max}=97\ cm/s$

Hence, this is the required solution.

Write a scientific explanation to describe where earthquakes and volcanoes most commonly occur and their relation to plate bound

vovangra [49]

Earthquakes and volcanoes most commonly occur around plate boundaries because of the movement from the plate boundaries. The interactions between the plates by moving under, upon, or sliding against other boundaries may cause earthquakes and volcanoes.
