<h3>Answer</h3>
option C)
The wavelength has a length between 7.0 cm and 8.0 cm and the amplitude lies between 1.0 cm and 2.0 cm.
<h3>Explanation</h3><h2>1)</h2>
The amplitude of a wave is the height of a wave as measured from the highest point on the wave, peak, to the rest point or from the lowest point on the wave, trough, to the rest point.
By looking at the image
rest point is at 5cm and crest is at 3.3 cm (y-axis)
so amplitude = 5 - 3.3
= 1.7 cm (approximately)
<h2>2)</h2>
Wavelength refers to the length of a wave from one peak to the next.
one crest is at 2cm and the other crest is at 10cm (x-axis)
so wavelength = 10 - 2
= 8 cm (approximately)

The answer is B.) I took the test.
Explanation:
Atoms are the components of ordinary matter, also called baryonic matter, which only represents 4% of the universe, while the remaining 96% would be formed by what is known as dark matter and dark energy which constitute two of the unsolved problems in physics.
Explanation:
Food chain is linear sequence of the organisms through which the nutrients and the energy pass as one organism eats the another.
<u>If one species in the food chain ceases to exist, the other members in rest of chain could cease to exist too or may increase in population which can affect other food chains. (Breaking of food chain).</u>
This is because the animals in the food chain are dependent on the nutrient present in the another.
For example in the food chain,
Grass ---- Deer ------ Lion
If all deer extinct, the lion will die as they will have nothing to feed on and the population of grass increases.
The correct answer is option B, representational
All the painters in Peale family were involved in paintings which represent the day today life activities or were portraits or mimic some natural forms.
Charles Willson Peale , the head of the Peale family was known for painting sixty portraits of the first American president, George Washington. He also painted portraits of portraits of notable people of the society such as Benjamin Franklin, Thomas Jefferson etc.
Most of the paintings of peale family were based on the theme of family, art and science. Six of Peale’s son were known for their renaissance paintings. His oldest son Raphelle was known for still life paintings.
Titian Ramsay Peale, Charles’ youngest son was a naturalist painter.
