So, the final velocity of the ball when it is 10.0 m above the ground approximately <u>26.2 m/s</u>.
<h3>Introduction</h3>
Hi ! In this question, I will help you. This question uses the principle of final velocity in free fall. Free fall occurs only when an object is dropped (without initial velocity), so the falling object is only affected by the presence of gravity. In general, the final velocity in free fall can be expressed by this equation :
With the following condition :
- v = final velocity (m/s)
- h = height or any other displacement at vertical line (m)
- g = acceleration of the gravity (m/s²)
<h3>Problem Solving</h3>
We know that :
= initial height = 45.0 m
= final height = 10.0 m- g = acceleration of the gravity = 9.8 m/s²
Note :
At this point 10 m above the ground, the object can still complete its movement up to exactly 0 m above the ground.
What was asked :
- v = final velocity = ... m/s
Step by Step
<h3>Conclusion</h3>
So, the final velocity of the ball when it is 10.0 m above the ground approximately 26.2 m/s.

Answer:
Momentum
Explanation:
The property of a moving object having mass m and moving with velocity v is called its momentum. It is given by the mathematical form as follows :
It is a vector quantity. Its SI unit of kg-m/s.
Answer: ??? D? dont quote me on it tho <3
Explanation:
CORRECT ANSWER:
a- Cell-surface receptors bind polar signaling molecules; intracellular receptors bind nonpolar signaling molecules.
STEP-BY-STEP EXPLANATION:
The complete question from book is
According to Figure 9.6, what is a key difference between cell signaling by a cell-surface receptor and cell signaling by an intracellular receptor?
a- Cell-surface receptors bind polar signaling molecules; intracellular receptors bind nonpolar signaling molecules.
b- Signaling molecules that bind to cell-surface receptors lead to cellular responses restricted to the cytoplasm; signaling molecules that bind to intracellular receptors lead to cellular responses restricted to the nucleus.
c- Cell-surface receptors bind to specific signaling molecules; intracellular receptors bind any signaling molecule.
d- Cell-surface receptors typically bind to signaling molecules that are smaller than those bound by intracellular receptors.
e- None of the other answer options is correct.
