A peregrine falcon dives 176 meters through the air in 8 seconds. Its
average speed during the dive is 22 m/s. *
Answer:
This question is asking to find the average speed during the dive. The answer is 22m/s.
Explanation:
Average speed of a substance can be calculated knowing it's distance over a particular amount of time.
The formula for average speed is:
Average speed (s) = Distance (d) / time (t)
In the case of this question where A peregrine falcon dives 176 meters through the air in 8 seconds, the distance of the falcon is 176m, while the time is 8s. Hence;
Average speed = 176/8
Average speed = 22
Therefore, the average speed of the falcon diver is 22m/s.

Which of the following isotopes are NMR inactive?
a. 1H
b. 12C
c. 15N
d. 16o
e. 19F
f. 31P
Answer:
12C and 16O
Explanation:
Here, we want to select which of the options are NMR inactive. For an isotope to be NMR inactive, then the net nuclear spin is zero.
What this means is that the number of proton present coupled with the number of neutrons are an even number pair.
What we are saying here is that the number of protons is an even number while the number of neutrons too is an even number. So the net nuclear spin in this case is zero.
in the case of oxygen, we have 8 protons and 8 neutrons. This makes the nuclear spin zero and consequently makes the isotope NMR inactive.
Same is in the case of carbon. There are 6 protons and 6 neutrons and this also makes nuclear spin zero .
In all the other isotopes in the question, we have odd number even number or even number odd number pairs of protons and neutrons.

HELP 100 POINTS WILL MARK BRAINLIEST In ancient times, early astronomers watched stars travel across the sky in one direction for several months, then over the course of a few weeks the stars would reverse course and move in the opposite direction. After these few weeks, the stars would reverse direction again and resume their original course. The ancient astronomers called these “wanderer stars”. After more research was done, it was found that these “wanderer stars” were actually other planets. As more data was collected, it was shown that all planets move at different speeds as they travel in their orbits around the Sun. As the Earth moves in its orbit, it moves faster than some planets and slower than others. This causes the Earth to “pass” some planets as it travels, which results in the appearance that the other planets move backwards. Is this a description of a scientific law or scientific theory? 100 points PLEASE HELP
Why do fireworks produce different colors
Two or more than two atoms with different physical or chemical properties can not combine together to form an element. Energy is the only factor that determines the color of light of fireworks.
What is element?Element generally consist of atoms or we can atoms combine to form element. Atoms of an element is always same, means all the properties of all atoms of one type of element is same.
Fireworks has many different types of element. When any element is given an energy. Then the process of excitation of electrons takes place from its outermost shells. Every element absorb characteristic wavelength of energy and releases light to the corresponding wavelength.
Therefore, energy is the only factor that determines the color of light of fireworks.

substance A is a nonpolar liquid and has only dispersion forces among its constituent particles. Substance B is also a nonpolar liquid and has about the same magnitude of dispersion forces among its constituent particles as substance A. When substance A and substance B are combined, they spontaneously mix. Why
Explanation:
The substance A and B will mix into one solution as it is a solvent interactions which is greater than or equal to the solute- solute and the solvent-solvent interactions. Thus when such interactions occurs, it is greater or equal to the some of the other two possible interactions. And here both have the same kind of interaction, and same magnitude, so they will makes to form a solution and mixes properly and spontaneously.

The density of water at 40°C is 0.992 g/mL. What is the volume of 2.69 g of water at this temperature? V= mL
Answer:
[tex]\boxed {\tt 2.71169355 \ mL}[/tex]
Explanation:
Density can be found using the following formula:
[tex]d=\frac {m}{v}[/tex]
Rearrange the formula for v. Multiply both sides by v, then divide both sides by d.
[tex]d*v =\frac {m}{v}*v[/tex]
[tex]d*v=m[/tex]
[tex]\frac{d*v}{d}=\frac{m}{d}[/tex]
[tex]v=\frac{m}{d}[/tex]
The volume can be found by dividing the mass by the density. The mass is 2.69 grams and the density is 0.992 grams per milliliter.
[tex]m= 2.69 \ g\\d= 0.992 \ g/mL[/tex]
Substitute the values into the formula.
[tex]v=\frac{2.69 \ g}{0.992 \ g/mL}[/tex]
Divide. Note that the grams, or g, will cancel each other out.
[tex]v=\frac{2.69}{0.992 \ mL}[/tex]
[tex]v= 2.71169355 \ mL[/tex]
The volume of the water is 2.71169355 milliliters.
