A. 1
B. 3
C. 2
D. 4
Answers
hope it helps have a great day!
Model 4 shows 4 electrons in the outer shell of the atom. Option D is correct.
What is an atom?The atom consists of matter that may be split without releasing electrical charges.
It's also the smallest unit of matter with chemical element features. As a result, the atom is the fundamental unit of science.
In the nucleus, proton and the neutron is existing. The condition of the atom to be electrically neutral is that the number of the proton and electron should be the same.
The outermost shell, is the shell containing electrons in which limited number of the electron can be existed. When an atom's outermost electron shell is full, it is the most stable and least reactive.
Model 4 shows 4 electrons in the outer shell of the atom. It is simply obtained by calculating the no electron in the shell.
Hence, option D is correct.

A wave has a wavelength of 4.9 m and a velocity of 9.8 m/s. The medium through which this wave is traveling is then heated so that the velocity is doubled. If the frequency remains constant, what is the wavelength of the heated wave? 2.5 m 9.8 m 14.7 m 19.6 m
Answers
Answer:
the wavelength is 9.8 meters
Explanation:
We can use the relationship:
Velocity = wavelenght*frequency.
Initially we have:
wavelenght = 4.9m
velocity = 9.8m/s
then:
9.8m/s = 4.9m*f
f = 9.8m/s/4.9m = 2*1/s
now, if the velocity is doubled and the frequency remains the same, we have:
2*9.8m/s = wavelenght*2*1/s
wavelenght = (2*9.8m/s)*(1/2)s = 9.8 m
Answer:
9.8

What types of changes in motion cause acceleration?
Answers
Answer:
Change in velocity and direction over a specific period of time.
Explanation:
In physics, acceleration can be defined as the rate of change of the velocity of an object with respect to time.
This simply means that, acceleration is given by the subtraction of initial velocity from the final velocity all over time.
Hence, if we subtract the initial velocity from the final velocity and divide that by the time, we can calculate the acceleration of an object.
Mathematically, acceleration is given by the equation;
[tex]Acceleration (a) = \frac{final \; velocity - initial \; velocity}{time}[/tex]
[tex]a = \frac{v - u}{t}[/tex]
Where,
a is acceleration measured in [tex]ms^{-2}[/tex]
v and u is final and initial velocity respectively, measured in [tex]ms^{-1}[/tex]
t is time measured in seconds.
Hence, the types of changes in motion that cause acceleration is a change in velocity and direction over a specific period of time.

Define A Gamma Ray .....---_---__☘️
Answers
Answer:
gamma ray, or gamma radiation (symbol γ or {\displaystyle \gamma } \gamma ), is a penetrating form of electromagnetic radiation arising from the radioactive decay of atomic nuclei. It consists of the shortest wavelength electromagnetic waves and so imparts the highest photon energy. Paul Villard, a French chemist and physicist, discovered gamma radiation in 1900 while studying radiation emitted by radium. In 1903, Ernest Rutherford named this radiation gamma rays based on their relatively strong penetration of matter; in 1900 he had already named two less penetrating types of decay radiation (discovered by Henri Becquerel) alpha rays and beta rays in ascending order of penetrating power.

Answer:
Well a lot of people believes in evolution. But in fact evolution is actually clearly impossible because how can dead which is Non-Living bacteria and dirt make something alive like living. And anyway there's a lot of thing's in nature that shows there is a creator. Like how does bees know when there honey comb is to warm to start fanning there wings to cool the honey comb down? And like human beings for example we didn't generate from aps. Yes there smart like us and sorta human like but the way our bodies are designed is wayyyyy to complicated. For example our brain its a computer we dont shut it on and off it's always running constantly and we dont have to worry about turning our brain on or off. I know this wasent what u have asked but i made me think about it and also someone created the universe because the whole universe hangs on nothing but they stay aligned. So this shows that there is a creator though.

Arthur conducts a controlled experiment several times. The results of each test show that his hypothesis is not supported. Which of these best describes why
this hypothesis is still valuable?
Answers
Hello. You did not inform the experiment that Arthur is conducting, which makes it impossible for your question to be answered accurately. However, I will try to help you in the best possible way.
The hypothesis is an assumption that is made before the experiment is carried out. This hypothesis is formed with the observation of some phenomenon of nature where the researcher believes that two or more elements interact to form a result. In this case, the experiment is carried out to determine whether the assumption, that is, the hypothesis is false or true. In the event that an experiment determines that the hypothesis is false, two things may have occurred: (a) the experiment was set up, or analyzed incorrectly, (b) the elements tested have no relation to the observed phenomenon.
