<u>Answer:</u>
<em>1. A NaCl solution with a concentration of 50g/100mL of water at 40°C:</em> The NaCl solution with a given concentration is saturated at this temperature .As the temperature increases the solution will more dissolves.
<em>2. A sugar solution with a concentration of 200g/100mL of water at 40°C: </em>The sugar solution with a given concentration is saturated at this temperature. As the temperature increases the solution will more dissolves.
<em>3. A sugar solution with a concentration of 240g/100mL of water at 40°C:</em> The sugar solution with a given concentration is saturated at given temperature.
Answer: Tsunami.
Explanation :
Tsunami is the result of a sudden vertical offset in the ocean floor and is most often the result of plate movement on the ocean floor.
Tsunami is caused due to the displacement of a large volume of water like in an ocean. It consists of a series of waves. It destroys coastlines and coastal settlements. It is also known as a tidal wave.
So, the correct option is (b) Tsunami.
Answer:
v = 7934.2 m/s
Explanation:
Here the total energy of the Asteroid and the Earth system will remains conserved
So we will have
![-\frac{GMm}{r} + \frac{1}{2}mv_0^2 = -\frac{GMm}{R} + \frac{1}{2}mv^2](https://tex.z-dn.net/?f=-%5Cfrac%7BGMm%7D%7Br%7D%20%2B%20%5Cfrac%7B1%7D%7B2%7Dmv_0%5E2%20%3D%20-%5Cfrac%7BGMm%7D%7BR%7D%20%2B%20%5Cfrac%7B1%7D%7B2%7Dmv%5E2)
now we know that
![v_0 = 660 m/s](https://tex.z-dn.net/?f=v_0%20%3D%20660%20m%2Fs)
![M = 5.98 \times 10^{24} kg](https://tex.z-dn.net/?f=M%20%3D%205.98%20%5Ctimes%2010%5E%7B24%7D%20kg)
![m = 5 \times 10^9 kg](https://tex.z-dn.net/?f=m%20%3D%205%20%5Ctimes%2010%5E9%20kg)
![r = 4 \times 10^9 m](https://tex.z-dn.net/?f=r%20%3D%204%20%5Ctimes%2010%5E9%20m)
![R = 6.37 \times 10^6 m](https://tex.z-dn.net/?f=R%20%3D%206.37%20%5Ctimes%2010%5E6%20m)
now from above formula
![GMm(\frac{1}{R} - \frac{1}{r}) + \frac{1}{2}mv_0^2 = \frac{1}{2}mv^2](https://tex.z-dn.net/?f=GMm%28%5Cfrac%7B1%7D%7BR%7D%20-%20%5Cfrac%7B1%7D%7Br%7D%29%20%2B%20%5Cfrac%7B1%7D%7B2%7Dmv_0%5E2%20%3D%20%5Cfrac%7B1%7D%7B2%7Dmv%5E2)
now we have
![2GM(\frac{1}{R} - \frac{1}{r}) + v_0^2 = v^2](https://tex.z-dn.net/?f=2GM%28%5Cfrac%7B1%7D%7BR%7D%20-%20%5Cfrac%7B1%7D%7Br%7D%29%20%2B%20v_0%5E2%20%3D%20v%5E2)
now plug in all data
![2(6.67 \times 10^{-11})(5.98 \times 10^{24})(\frac{1}{6.37 \times 10^6} - \frac{1}{4 \times 10^9}) + (660)^2 = v^2](https://tex.z-dn.net/?f=2%286.67%20%5Ctimes%2010%5E%7B-11%7D%29%285.98%20%5Ctimes%2010%5E%7B24%7D%29%28%5Cfrac%7B1%7D%7B6.37%20%5Ctimes%2010%5E6%7D%20-%20%5Cfrac%7B1%7D%7B4%20%5Ctimes%2010%5E9%7D%29%20%2B%20%28660%29%5E2%20%3D%20v%5E2)
![v = 7934.2 m/s](https://tex.z-dn.net/?f=v%20%3D%207934.2%20m%2Fs)
