Answer: H2o
Explanation:
because oxygen is in the air
Answer:
16.52 lb NaCl will be in the tank at the end of 3 hours.
Explanation:
Let s(t) = gal of NaCl in a container at time t (in minutes).
s'(t) = The rate at which the amount of gal of NaCl in the container is changing.
s'(t) = Rate of NaCl going in - Rate of NaCl going out
By variable separable method we get
Integrate both sides.
100 Ib of NaCl are initially dissolved in 600 gal of a NaCl solution in a container. it means s(0)=100.
Therefore the required function is
.... (1)
We need to find the amount of NaCl will be in the tank at the end of 3 hours.
3 hours = 180 minutes.
Substitute t=180 in equation (1).
Therefore, 16.52 lb NaCl will be in the tank at the end of 3 hours.
Answer:
the 4 weather fronts are:
1- cold fronts
2- warm fronts
3- stationary fronts
4- occludent fronts
Explanation:
the resultant weather of the 4 fronts are
1- cold front-- cold winds and dry and cold weather
2- warm front-- brings warm weather
3- stationary front-- behave like warm fronts but are more quiescent
4- occludent front-- these indicate mature storm systems
