Ответ:
Second option is correct.
Explanation:
Filtration is the method of removing impurities solid particles from liquid.
Distillation is the method of removing impurities in a boiling liquid mixture.
Osmosis is the movement of water from low concentration to high concentration through a plasma membrane.
Reverse osmosis is the method of purification of water to remove ions and unnecessary molecules from drinking water.
We have given the situation that "There is a water sample contaminated with salt and micro organisms."
We need to purify the water.
Filtration is the best method to purify the water and remove the salt and micro organisms.
As there is slight difference between filtration and distillation.
In distillation we need to boil the water , so there heat is needed for this whereas in filtration, it just remove solid from fluid without being heated.
Hence, Second option is correct.
Ответ:
1.8 km
Step-by-step explanation:
The scale on the map is 1 : 15000.
This means that every 1 cm on the map is equal to 15000 cm on the ground.
12 cm on the map will therefore be:
12 * 15000 = 180000 cm
Let us convert to kilometres:
100000 cm = 1 km
180000 cm = 180000 / 100000 = 1.8 km
12 cm on the map will be 1.8 km on the ground.
