The largest distance moved by a particle of a vibrating body from its equilibrium position is called amplitude. Wave B has higher energy because wave it has a higher amplitude.
<h3>What is the amplitude of a wave?</h3>
The largest distance moved by the particles on either side of the mean position is the amplitude of a wave.
The maximum height of either crest or trough from its equilibrium position is called amplitude.
Hence Wave B has higher energy because it has a higher amplitude.

Set up a unit conversion problem, arrange units to convert minutes to seconds, then cancel all time units.
8.3 minutes x (60 seconds/1 minute) x ( 3.00x10^8 meters/1 second) = 149,400,000,000 meters
Since the time is the term with the fewest number of significant figures (2), your answer should only be expressed with two sig figs as well.

The difference in the mass of carbon dioxide in 500 kg of air in 2013 compared to 1800 is 0.06 Kg
<h3>Data obtained from the question</h3>
- Year 1800 percent = 0.028%
- Year 2013 percent = 0.040%
- Mass of air = 500 Kg
- Difference =?
<h3>How to determine the mass of CO₂ in 500 Kg in year 1800</h3>
- Year 1800 percent = 0.028%
- Mass of air = 500 Kg
- Mass of CO₂ =?
Mass = percent × mass of air
Mass of CO₂ = 0.028% × 500
Mass of CO₂ = 0.14 Kg
<h3>How to determine the mass of CO₂ in 500 Kg in year 2013</h3>
- Year 1800 percent = 0.040%
- Mass of air = 500 Kg
- Mass of CO₂ =?
Mass = percent × mass of air
Mass of CO₂ = 0.040% × 500
Mass of CO₂ = 0.2 Kg
<h3>How to determine the difference</h3>
- Mass of CO₂ in year 1800 = 0.14 Kg
- Mass of CO₂ in year 2013 = 0.2 Kg
- Difference =?
Difference = mass in 2013 - mass in 1800
Difference = 0.2 - 0.14
Difference = 0.06 Kg

The answer is b) false. Stars are mainly classified by their spectra (the elements they absorb) and their temperature.
Answer:
M. A change that causes the gene to increase the amount of lactase ir produces will increase a person's ability to break down lactose
Explanation:
Lactose is a sugar found in dairy products. Humans require an enzyme, called lactase, to break down the sugar in the body. This enzyme is produced by the lactase gene.
Some people have some variation in their gene that means they do not produce very much lactase. This means they do not produce sufficient amount of the enzyme to break down the sugar lactose found in milk. This causes them to feel ill and get abdominal pain when they eat dairy, because their body can't break down the sugar.
Therefore, a change in the gene that causes it to produce more lactase will make people more able to consume lactase. A change that decreases the amount of lactase enzyme will have the opposite effect.
The source of protein and minerals found in dairy are not processed by lactase, so R is not correct.
