1. When an object is moving away from us, the light from the object is known as redshift, and when an object is moving towards us, the light from the object is known as blueshift.
2. A wavelength increases in size, and its frequency, and energy decrease.
3. The frequency of a wave increases, and its wavelength decreases.
Redshift is an important term for astronomers. The term can be taken literally. The wavelengths of light are stretched and perceived as shifting toward the red portion of the spectrum. The same thing happens to sound waves when the source moves relative to the observer.
As the wave frequency decreases, the wavelength increases as long as the wave velocity remains constant. If the wave speed stays the same as the frequency decreases, it means that fewer wave peaks or troughs pass through a given point in a given time period. The number of complete wavelengths in a given unit of time is called frequency. Frequency and energy decrease with increasing wavelength.

Answer:
It increases by four times the initial amplitude.
Explanation:
The amplitude of a sounde is inversely proportional to the square of the distance between the listener and the sound source:
In this problem, the distance is decreased to hald the initial distance, so we can write
therefore, the new amplitude will be
So, the amplitude increases by a factor 4.
People can break down the rock by touching or the heat can even break down the rock
I believe it’s D) it will increase by 10x because when temperature increasing particles move faster causing things to expand like when you put a bottle of syrup in the microwave.
Answer:
They have the same current.
Explanation:
According to the Ohm's Law, resistors in series have the same current, distinct potential differences and resistances. The case for n resistors in series are:
