Answer:
W = 1418.9 J = 1.418 KJ
Explanation:
In order to find the work done by the pull force applied by Karla, we need to can use the formula of work done. This formula tells us that work done on a body is the product of the distance covered by the object with the component of force applied in the direction of that displacement:
W = F.d
W = Fd Cosθ
where,
W = Work Done = ?
F = Force = 151 N
d = distance covered = 10 m
θ = Angle with horizontal = 20°
Therefore,
W = (151 N)(10 m) Cos 20°
<u>W = 1418.9 J = 1.418 KJ</u>

</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>
