Red light has a _____ wavelength and a _____ frequency than does blue light.
Harlamova29_29 [7]
In a spectrum of visible light, we will see that red appears to have a longer wavelength than the blue light. Since wavelength and frequency are inversely proportional then, red will have a smaller frequency than does the blue light.

Which of the following determines the range of spectral lines produced during electron transition?. . A.The total number of ener
KengaRu [80]

Answer: A.The total number of energy levels the electron can jump to.

Explanation:

Spectral lines are bright or dark lines over continuous spectrum which occur due to emission or absorption of energy.

When an electron jumps to or from one energy level to another energy level, spectral lines are produced. The range of spectral lines depends on the number of energy levels available to which the electron can jump. This depends the amount of energy gained/lost by the electron.

Thus, the correct answer is: A.The total number of energy levels the electron can jump to.

What is Newton's second law of motion
Alexandra [31]
Newton’s second law is that the acceleration of an object is directly related to the net force and inversely related to its mass. Acceleration of an object depends on two things, force and mass.

9. When considering a magnet's force of attraction over a known distance, you would expect the strength of attraction 4 inches a
slavikrds [6]

Answer: B. 16 times

Explanation:

The mathematic expression for a magnetic force F_{M} between two magnets is:

F_{M}=K_{M}\frac{m_{1}m_{2}}{r^{2}}   (1)

Where:

K_{M} is a constant

{m_{1} and {m_{2} are the magnetic charges, which depends on the size of each magnet

r is the distance beteween both magnets

As we can see, this force in inversely proportional to the square of the distance. This means that if we increase the distance, the magnetic force will decrease.

Now, if we increase this value by 4 inches from 1 inch:

F_{M}=K_{M}\frac{m_{1}m_{2}}{{(4)}^{2}}   (2)

F_{M}=K_{M}\frac{m_{1}m_{2}}{16}   (3)

This means the strength of attraction will be 16 times weaker.
