</span>Question : What part of the plant that transport
water from its root to its leaves.
The answer is the stem. The stem connects the plant’s root and leaves, it is
responsible for transporting water that is absorbed by the root going to the
leaves, it is also responsible for transporting nutrients absorbed with the
leaves coming from the sun or any nutrients going to the roots to make is grow
faster and healthy. Stem is the one that connects leaves and root and the one
the does the transporting job.</span>
Answer:
7.6427m/s
Explanation:
Given:
#Applying the conservation of momentum along the x-axis:
#And along y-axis:
#Solving for :
#By substitution in the x-axis equation:
Hence the original speed of the ball before impact is 7.6427m/s

Explanation:
Answer:
B: Greatest, A: Second greatest, C: Second geratest.
Explanation:
We can calculate the heat of fusion of a material (ΔHfus), which is the heat required to melt 1 kg of material, using the following expression.
ΔHfus = Q/m
where,
Material A
ΔHfus = 200 J/4 kg = 50 J/kg
Material B
ΔHfus = 300 J/5 kg = 60 J/kg
Material C
ΔHfus = 300 J/6 kg = 50 J/kg
Then, considering the heats of fusion,
B: Greatest, A: Second greatest, C: Second greatest.
