Answer:
t = 2.2 s
Explanation:
Given that,
Height of the roof, h = 24.15 m
The initial velocity of the pumpkin, u = 0
We need to find the time taken for the pumpkin to hit the ground. Let the time be t. Using second equation of kinematics to find it as follows :

Here, u = 0 and a = g

So, it will take 2.22 s for the pumpkin to hit the ground.
Answer:
I assume the higher notes would make the rice vibrate more easily, so a flute.
Answer:
The following explanatory section gives an explanation of this question.
Explanation:
- This means that perhaps the bubble moves more than a certain duration throughout the calibration breath meter offers the rate as well as oxygenation consumed inside this cell.
- Inside that respirometer, oscillation of something like the bubble gave a technique of multiplying the quantity of oxygenation that is used by the seedlings mostly through cell membrane breathing.
Rosalind Franklin, James Watson, and Francis Crick’s discovered the DNA's Double Helix.
<h3>What is DNA?</h3>
DNA is an abbreviation for deoxyribonucleic acid and it can be defined as the molecules that are found within cells, and they are saddled with the responsibility of storing genetic information in living organisms.
In 1953, James Watson and Francis Crick's used other scientists' work to create a model of DNA in that they used Rosalind Franklin's photo to help them determine that deoxyribonucleic acid (DNA) was a double helix.
Furthermore, the discovery of DNA's Double Helix by Rosalind Franklin, James Watson, and Francis Crick led to modern molecular biology, which has helped many scientists and researcher to understand how genes control the chemical processes in the body of a living organism.

Answer:
support lights as a wave
Explanation:
In the model of light as a particle, the experimenter would expect to see one small hole of light emerging on the wall. However, as the light spreads out, it behaves much like a wave that diffracts when going through a small hole.
