a scientist divided a population of fruit flies into two containers, each with a different kind of food. then she bred the fruit

flies under these conditions for many generations. lastly, she put the fruit flies from the two containers together again and observed which flies mated. which question was the scientist most likely testing? a. do well-fed fruit flies make good pets? b. what kind of food do fruit flies prefer? c. how many species of fruit flies can mate with each other? d. will fruit flies bred under different conditions mate?

<span>d. will fruit flies bred under different conditions mate? Let's look at the possible choices and see which of them make any sense given the experiment. a. do well-fed fruit flies make good pets? Seems kinda silly, but if this were the question being asked, I suspect the experiment would have some fruit flies that were well fed as well as some fruit flies that were starved and would then compare how those 2 populations of fruit flies interacted with people. But that wasn't done, so it's unlikely this is the question being asked. b. what kind of food do fruit flies prefer? Each population of fruit flies weren't given a choice as to available foods. So their preferences didn't come into play about what they were allowed to eat. So this question is also unlikely. c. how many species of fruit flies can mate with each other? The scientist started with a single population and divided it into two sub groups. There doesn't seem to be a large number of species of different fruit flies here, so this is also an unlikely question. d. will fruit flies bred under different conditions mate? The scientist started with a single population of fruit flies and divided them into two groups. Each group was allowed to breed for many generations with a different food for each group (e.g. Allowed to breed under different conditions). After they were both well established, the groups were merged together and observed which ones mated. It looks like this question is being answered. So this is the correct solution.</span>

In the ground state of hydrogen, according to the Bohr model, an electron orbits 5.3 x 10-11 m from the nucleus. It undergoes a
Readme [11.4K]

Answer:

Explanation:

Given

radius of electron(r)=5.3\times 10^{-11} m

centripetal acceleration (a_c)=9\times 10^22 m/s^2

we know

a_c=\frac{v^2}{r}

v=\sqrt{r\times a_c}

v=\sqrt{5.3\times 10^{-11}\times 9\times 10^{22}}

v=\sqrt{47.7\times 10^11}

v=21.84\times 10^5 m/s

(b)For n=10

r=100\times 5.3\times 10^{-11} m\approx 5.3\times 10^{-9} m

a_c=10^4\times 9\times 10^{22} m/s^2

a_c=9\times 10^{26} m/s^2

v=\sqrt{r\times a_c}

v=\sqrt{9\times 10^{26}\times 5.3\times 10^{-9}}

v=21.84\times 10^8 m/s

When a light bulb is connected to a 4.5 V battery, a current of 0.16 A passes through the bulb filament. What is the resistance
larisa [96]

Answer:

R = 28.125 ohms

Explanation:

Given that,

The voltage of a bulb, V = 4.5 V

Current, I = 0.16 A

We need to find the resistance of the filament. Using Ohm's law,

V = IR

Where

R is the resistance of the filament

So,

R=\dfrac{V}{I}\\\\R=\dfrac{4.5}{0.16}\\\\R=28.125\ \Omega

So, the resistance of the filament is equal to 28.125 ohms.
