Vascular tissue is responsible for transporting water and nutrients in plants.The Vascular tissue consists of the Xylem and the Phloem. The main function of the Xylem is to transport water and minerals throughout all parts of the plant. Phloem on the other hand is responsible for transporting organic molecules that are larger in size. The vascular system, consisting on the Xylem and the Phloem runs from the roots of the plats through the branches and upto the leaves. It controls the total transportation of the water and nutrients.
<span>The long tubes that carry water and sugar from the leaves to the rest of the plat are known as phloem. The Xylem on the other hand carries water and small minerals from the root through the branches to the leaves for producing glucose and oxygen. The xylem and phloem are two most important parts of plants that are required for the survival of the plant. Water is mainly carried by the Xylem but some amount of water goes through the phloem for transporting the glucose that is manufactured. The process of photosynthesis is highly dependent on Xylem and Phloem.<span> </span></span>
Answer:
A) G = m³/kg.s²
B) E = kg.m²/s²
Explanation:
A)
The given relation is:
F = Gm₁m₂/r²
where, the units of all variables are:
F = Force = kg.m/s²
m₁ = m₂ = mass = kg
r = distance = m
G = Gravitational Constant = ?
Therefore,
kg.m/s² = G(kg)(kg)/m²
(kg.m/s²)(m²/kg²) = G
<u>G = m³/kg.s²</u>
<u></u>
B)
The given equation is:
E = mc²
where, the units of all variables are:
m = mass = kg
c = speed = m/s
E = Energy = ?
Therefore,
E = (kg)(m/s)²
<u>E = kg.m²/s²</u>
This is the correct answer, which is not present in any option.
I think the correct answer from the choices listed above is option D. Solar cells convert electromagnetic energy into electrical energy. This is because the photons from the rays of light are electromagnetic waves or particles. Hope this answers the question.
15,000J/.15% = 100,000 J
If you want to check,
Multiply 100,000 by .15 and you get 15,000 J
Newton's third law: For every action, there is an opposite and equal reaction.
