The fronts that produce the most storms are those that have the highest difference in temperature, and the highest levels of water vapor. Warm, moist air is unstable, and contact with colder air can trigger extreme weather events. The key factor is convergence of winds produced in the area along the front<span>.</span>
I attached a free body diagram for a better understanding of this problem.
We start making summation of Moments in A,
Then we make a summation of Forces in Y,
At the end we calculate the angle with the sin.
Answer:
time require is 23.33 hours
Explanation:
given data
time t1 = 7 hours
time t2 = 10 hours
to find out
how long it take to fill vat if both pipe left open
solution
we consider here vat volume is v
so speed = volume / time .................1
inlet speed = v / 7 .................2
outlet speed = v / 10 ..................3
so from equation 2 and 3
net speed is = v / 7 - v / 10
net speed = 3
/70 × v
so here time is
time = v / net speed
time =
time = 70 / 3 = 23.33
so time require is 23.33 hours
