kindly someone help me with Q9 mj13 qp12
how to we solve this?
the ans is A
try to convert things into SI units en make a formula of Kg/S
multiplying Speed , density , area gives u Mass /second units thats all wat u need!! Multiply all those quantities.......then put formula
F=ma
F=m*(v-u)/t (here just focus mass per unit time ,the answer u had before)
V (v=33)
f=475.2*(33) =15681.6 approx answer!!!

P.S - Answer is D :/
