<span>You may have noticed that there
are plants which do not have green leaves. Some plants are green because of a type of
pigment called chlorophyll. Plant cells
contain chloroplast which constitutes the pigment chlorophyll. Chlorophyll
absorbs red light and deep-blue light, hence, the rest of the sunlight spectrum
which is being reflected causes the plant to look green. When light reflects off on leaves into your eyes, the leaves take
in every hue of the rainbow, except for the color green, thus reflected into
your eyes and makes the leaves appear
green.</span>
This would be called the battery. Hope this helps.
Answer:
The atmosphere which contains nitrogen, oxygen, carbon dioxide, and other gases essential for life, contributes to the rainforest climate. The rainforest is hot, humid and helps balance the amount of carbon dioxide in the atmosphere by absorbing it and releasing more oxygen which is important for climate change.
The hydrosphere, which is the combination of various types of water sources and types found in air, in the form of water vapor; water found below the earth's surface and above, also contributes to the rainforest climate. The frequent rainfall dictates the vegetation growth in that area which also creates weather patterns due to the contribution of the atmosphere and the hydrosphere. The hydrosphere is important in the formation of rain. A rainforest of frequent rainfall indicates a large amount of the combination of various types of water sources and types found in a particular area, which release the water back onto the rainforest.
Answer:
a) V1=11.05m/s V2=92.07m/s V3=17.24m/s
b) KE = 16238.26J
Explanation:
For tangential speeds:
For the kinetic energy, it can be calculated as:
Where:
So,
KE=16238.26J
Answer:
No
Explanation:
Given that
Weight of the aluminium block = 10 N
Weight of the aluminium lead = 10 N
We know that
Weight = Volume x Density x g
Wt= V x ρ x g
The density of aluminium ,ρ=2810 kg/m³
The density of lead ,ρ=11343 kg/m³
From above we can say that density of lead is more than the density of aluminium that is why the volume of the aluminium will be more than the volume of the lead for same weight.So aluminium will displace the water but lead will not displace the water.
So the answer is ,lead does not displace the water.
