Three components in a parallel circuit have individual resistances of r1, r2, and r3. What formula can you use to determine the total resistance of the circuit?
A. R=r1+r2+r3
B. R=1r1+1r2+1r3
C. 1R=r1+r2+r3
D. 1R=1r1+1r2+1r3
Answer:
D. 1R=1r1+1r2+1r3
Explanation:
If three components are arranged to form a parallel circuit, and the individual resistance of these components are r1, r2, and r3 respectively, the formula for finding the total resistance R is: 1R=1r1+1r2+1r3.

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?
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.

What types of changes in motion cause acceleration?
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.

B.waxing crescent
C.new moon
D.first quarter
Answer:
new moon phase
Explanation:
During the new moon phase, the moon is not visible. Sometimes it can be detected by noting the visible absence of the stars that it blocks. Additionally, during new moon, sometimes enough light is reflected off the surface of the Earth that the disk of the moon is faintly visible.
Answer:
Everyone knows new moon is NOT visible
Explanation:
If you're doing an assignment of the moons, I hope this helps.
And there you have it! :]
Also, a new moon is the only phase that is not visible, It's not even visible during the day time.
Mario and Patience are making cookies. They are ready to drop balls of dough on baking sheets. They have baking sheets made of treated glass, aluminum, stainless steel, and copper. The specific heats of these substances are:
Treated glass = 0.75 J/g • °C

Stainless steel = 0.50 J/g • °C
Copper = 0.39 J/g • °C
Based on the specific heat values, which sheet is going to warm up the quickest, and, therefore, bake the cookies the fastest?

If 80,000 Joules of heat is absorbed by 210 grams of ice at 0°C, what happens to the ice?
It partially melts and stays at 0°C
It completely melts but stays at 0°C
It completely melts and has a final temperature of 11.2°C
It completely melts and has a final temperature of 22.4°C
It completely melts and has a final temperature of 33.6°C
Answer:
It completely melts and has a final temperature of 22.4°C
Explanation:
(I am very bad at explaining, I am not a teacher, I am a student but I had exact same question on my test so I wanted to help.)
Okay, well to find the Heat required to melt Ice, we have to use the equation:
Q=(m·cΔT)+(m·hf)
Q= HeatM= MassC= Specific heatΔT= Change in temperature. hf= heat fusionSo we can just plug in the values into the equation and see which one adds up too 80,000. (there is probably a better way i just did it this way)
For this situation, we know that:
Mass=210 gramsSpecific heat = 2.10 (I got this number 2.10 from the internet. The universal number for specific heat of ice is 2.10 J/g°C ) Change in temperature= 0 °C or 11.2 °C or 22.4 °C or 33.6 °C (all the answers) Heat fusion=334 (universal number for heat fusion of melting ice is 334)So we can just change the value of change and temperature and see which one equals 80,000.( I will bold the value of change in temperature.)
Q=(m·cΔT)+(m·hf)
(210g)*(2.10)*(0)+(210)*(334)=70140(210g)*(2.10)*(11.2)+(210)*(334)=75079.2(210g)*(2.10)*(22.4)+(210)*(334)=80018.4(210g)*(2.10)*(33.6)+(210)*(334)=84957.6So which one equals 80,000? Equation #3 with the temperature at 22.4 °C
So the answer would be It completely melts and has a final temperature of 22.4°C.
Hope this makes sense, again I am not a teacher I am so bad at explaining, but I did my best. ;)

4. How much force is required to accelerate a 5 kg mass at 2 m/s??

Clearly, F1>F2, i.e., greater force would be required in accelerating a 2kg mass at 5m/s2.
Explanation:
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
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

In 3-4 sentences, briefly summarize how our solar system formed.
Answer:
Explanation:
Our solar system is formed by a dust storm, which created the planets. This info is grabbed by NASA, and people believe this is how the Solar System is formed. The sun is formed like this too.
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.
Explanation:
Hope this helps you in some way of form. :)
