Because of the greenhouse gases inside the greenhouse, and the gases trap the heat from the sun so the plant don't freeze, hope this helps
Answer:
44.64 seconds
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration due to gravity = 9.8 m/s²
![v^2-u^2=2as\\\Rightarrow v=\sqrt{2as+u^2}\\\Rightarrow v=\sqrt{2\times 4.2\times 1180+80.6^2}\\\Rightarrow v=128.01\ m/s](https://tex.z-dn.net/?f=v%5E2-u%5E2%3D2as%5C%5C%5CRightarrow%20v%3D%5Csqrt%7B2as%2Bu%5E2%7D%5C%5C%5CRightarrow%20v%3D%5Csqrt%7B2%5Ctimes%204.2%5Ctimes%201180%2B80.6%5E2%7D%5C%5C%5CRightarrow%20v%3D128.01%5C%20m%2Fs)
![v=u+at\\\Rightarrow 128.01=80.6+4.2t\\\Rightarrow t=\frac{128.01-80.6}{4.2}=11.29\ s](https://tex.z-dn.net/?f=v%3Du%2Bat%5C%5C%5CRightarrow%20128.01%3D80.6%2B4.2t%5C%5C%5CRightarrow%20t%3D%5Cfrac%7B128.01-80.6%7D%7B4.2%7D%3D11.29%5C%20s)
<u>Time taken to reach 1180 m is 11.29 seconds</u>
![v=u+at\\\Rightarrow 0=128.01-9.8t\\\Rightarrow t=\frac{128.01}{9.8}=13.06\ s](https://tex.z-dn.net/?f=v%3Du%2Bat%5C%5C%5CRightarrow%200%3D128.01-9.8t%5C%5C%5CRightarrow%20t%3D%5Cfrac%7B128.01%7D%7B9.8%7D%3D13.06%5C%20s)
<u>Time the rocket will keep going up after the engines shut off is 13.06 seconds.</u>
![v^2-u^2=2as\\\Rightarrow s=\frac{v^2-u^2}{2a}\\\Rightarrow s=\frac{0^2-128.01^2}{2\times -9.8}\\\Rightarrow s=836.05\ m](https://tex.z-dn.net/?f=v%5E2-u%5E2%3D2as%5C%5C%5CRightarrow%20s%3D%5Cfrac%7Bv%5E2-u%5E2%7D%7B2a%7D%5C%5C%5CRightarrow%20s%3D%5Cfrac%7B0%5E2-128.01%5E2%7D%7B2%5Ctimes%20-9.8%7D%5C%5C%5CRightarrow%20s%3D836.05%5C%20m)
The distance the rocket will keep going up after the engines shut off is 836.05 m
Total distance traveled by the rocket in the upward direction is 1180+836.05 = 2016.05 m
The rocket will fall from this height
![s=ut+\frac{1}{2}at^2\\\Rightarrow 2016.05=0t+\frac{1}{2}\times 9.8\times t^2\\\Rightarrow t=\sqrt{\frac{2016.05\times 2}{9.8}}\\\Rightarrow t=20.29\ s](https://tex.z-dn.net/?f=s%3Dut%2B%5Cfrac%7B1%7D%7B2%7Dat%5E2%5C%5C%5CRightarrow%202016.05%3D0t%2B%5Cfrac%7B1%7D%7B2%7D%5Ctimes%209.8%5Ctimes%20t%5E2%5C%5C%5CRightarrow%20t%3D%5Csqrt%7B%5Cfrac%7B2016.05%5Ctimes%202%7D%7B9.8%7D%7D%5C%5C%5CRightarrow%20t%3D20.29%5C%20s)
<u>Time taken by the rocket to fall from maximum height is 20.29 seconds</u>
Time the rocket will stay in the air is 11.29+13.06+20.29 = 44.64 seconds

Answer:
1. C: 31/14 Si becomes 31/15 because a nuetron
2. A: 238 92U because the very long half-life means a very small rate of decay
3. D: Charge conservation is not satisfied
4. B: of the four nuclear decay processes only the α-decay changes the baryon number and does so in increments of four
