Answer:
Flushing goldfish down the toliet
Explanation:
This would help the planet because goldfish are a very evasive species that has been harming our natural enviroments lakes and rivers. Ever since people have been flushing them down the toliet including me since I've had over six they have been finding their ways into our ecosytem and damaging nature. You may think that goldfish are a cute and small pet species to keep in a fish tank but the fish can grow in the right conditons up to 16.1 inches long and can top over five pounds in the wild. Unfortunately most goldfish never thrive like this in fish tanks due to nasty inadequate housing and feeding conditions. And most do not live up to their expected life span in the wild of 15 to even thirty years due to their living conditons. Did you know, goldfish will actually jump out of their tank in a final desperate search for better living conditions and enviroment to live in to meet their physiological needs. But lets get back to the problem so don't be to quick to feel sorry for them, when people flush them down the toliet they repopulate somehow in our lakes and rivers. Even through, it is not clear how they got there, which the suspected culprit is the sewer system. They threaten the natural enviroment tho because they are obnivores and they eat a mixtures of plants and animal specimen. You are probrably thinking why is this a problem, well its because goldfish are particullary greedy eaters and will eat, eat, and feast on the natural envrioment they infestated. And the waste they leave on the enviroment will promote the growth of algae which could cause an extent of enviromental damage. Of course goldfish are not impacted by this algae growth for adaptation reasons which shield them. This is not the main problem tho the main problem of this is that female goldfish can produce up to 1000 eggs at a time. And to make things worse unlike other fish species where the parents of the eggs leave the eggs for predaetors and well the elements of nature the goldfish instead guard their nest foriciously from predaetors that eat fish eggs in which effectively shields the populations young from danger. And to just add to the chaos the goldfish sadly have no real natural predaetor in the unitedstates which just causes more problems since they have no one killing them. And did I mention that they could live up to a real possibility of thirty years. And that they are forocious eaters that could eat a variety of types of foods. All of these facts in the end lead to two things first stop flushing your pet goldfish down the toliet and secondly now you know how golfish impact our planet.
Give brainliest please it took me over thirty minutes of thinking!
Dear friend,
How are you doing? I finally switched to my new school and it's been so hard adjusting. But I know I have a new chance at making new friends and memories. Also, I can learn new things, like interacting with new people and how to keep my anxiety low. I really miss us hanging out and how much we'd laugh and get in trouble at class. But i really hope to see you soon & that it hasn't gone terribly wrong for you since i left.
your friend,

Answer:
3.46x10⁴
Explanation:
Hello,
In this case, we can see that the number 34,560 has five significant figures, it means that if we want to write it with three, we must take the 3, 4 and 5 only. Nevertheless, since the 6 after the five is greater than 5, we can round such five to 6, so we obtain:
346
However, the decimal places cannot get lost, therefore, we move the given thousand to the three, so the number turns out:
3.46x10⁴
Best regards.
Answer:
c = 0.898 J/g.°C
Explanation:
1) Given data:
Mass of water = 23.0 g
Initial temperature = 25.4°C
Final temperature = 42.8° C
Heat absorbed = ?
Solution:
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
Specific heat capacity of water is 4.18 J/g°C
ΔT = 42.8°C - 25.4°C
ΔT = 17.4°C
Q = 23.0 g × × 4.18 J/g°C × 17.4°C
Q = 1672.84 j
2) Given data:
Mass of metal = 120.7 g
Initial temperature = 90.5°C
Final temperature = 25.7 ° C
Heat released = 7020 J
Specific heat capacity of metal = ?
Solution:
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
ΔT = 25.7°C - 90.5°C
ΔT = -64.8°C
7020 J = 120.7 g × c × -64.8°C
7020 J = -7821.36 g.°C × c
c = 7020 J / -7821.36 g.°C
c = 0.898 J/g.°C
Negative sign shows heat is released.
