Which of the following is an example of a decomposition reaction?a. photosynthesis
b. digestion
c. polymerization
d. exchange of ions between two compounds

Answers

The answer is (b) digestion.
A decomposition reaction is a process in which a single compound breaks into two or multiple elements or compounds. A best example is digestion where a large insoluble food molecules breakdowns into small water-soluble molecules so that they can be absorbed into the watery blood plasma.

The Doppler effect suggests that sound waves are relative to the observer. You know if an object is coming or going from the sound it makes. Light waves follow the Doppler effect also. However, instead of sound changing, you know if an object is coming or going _____.

Answers

A similar principle is observed with light as it is with sound. If an object is moving away from you the wavelengths gets longer, and towards the red light spectrum of the visible light spectrum, whereas if an object is moving towards you the wavelength will decrease towards the blue end of the spectrum

Answer:

from the color of the light

Brody and Ethel are arguing about waves. Brody says that waving his hand back and forth is a scientific wave. Ethel says that it is not. Which statement best describes who is correct?-Brody is correct because the wave involves an input of energy.
-Ethel is correct because energy is not carried from one place to another.
-Brody is correct because the pattern repeats.
-Ethel is correct because the motion has no pattern.

What would you expect to happen to the acceleration if all friction were removed from the ramp, making the net force even higher than 600 N?

Answers

Answer:

if the friction was removed from the ramp, the acceleration would drasticly increase, making it hard to stop.

Explanation:

The speed of sound waves through two different media, steel and air, was recorded. According to the graph, sound waves travel. A) through steel, but not through air
B) faster through steel than through air
C) faster through air than through steel
D) through steel and air at similar speeds

Answers

Answer: The correct answer is Option B.

Explanation:

Sound waves are a type of longitudinal waves. These waves are the waves in which particles of the medium travel in the direction of the wave. These waves require a medium to travel.

Sound waves travel faster in solids than in the gaseous medium because the particles in solid state lie close to each other and the vibrations of the sound waves travel faster when the particles lie closer to each other.

Hence, the correct answer is Option B.
Faster through steel than through air, B.

Choose the correct description, of what happens to the electron speeds in a more massive white dwarf. Choose the correct description, of what happens to the electron speeds in a more massive white dwarf. As the mass of a white dwarf increases, the pressure must increase to resist gravity. To do this, the electrons must move faster. As the mass of a white dwarf increases, the pressure must decrease to resist gravity. To do this, the electrons must move faster. As the mass of a white dwarf increases, the pressure must decrease to resist gravity. To do this, the electrons must move slower. As the mass of a white dwarf increases, the pressure must increase to resist gravity. To do this, the electrons must move slower.

Answers

Answer:

As the mass of a white dwarf increases, the pressure must increase to resist gravity. To do this, the electrons must move faster.

Explanation:

A white dwarf also known as degenerate dwarf is a star or an electron degenerate matter and is as massive as the Sun but only about as large in size as planet Earth.

The maximum mass of a white dwarf is about 1.4 times the mass of the Sun.

Also, as the mass of a white dwarf increases, the pressure must increase to resist gravity and to do this, the electrons must move faster.
