The answer is 35.9168 grams
<span>Soln:
•t: in min
•Q(t): quantity of dye in the tank at time t
•r in= 0: rate of dye poured into the tank per min. Since it is fresh water, so it
is zero.
•r out= density of dye×rate of fluid =Q/900×9: rate of dye flowing out.
•Q(0) = 1×900 g: initial amount of dye in the tank.
•{dQ/dt=rin-rout= 0-Q100 Q(0) = 900g•Q(t)=Ce-1/100t
•Q(0) = 900, C= 900, Q(t) = 900e-1/100t
•Q(t) = 0.01·Q(0), Q(0)e-1/100t= 0.01×Q(0),-t100= ln 0.01, t= 460min</span>
Oxygen is a pure substance, as it is composed of only a single kind of atom. Which is the oxygen atom, it cannot be broken or degraded down any further into constituents that make up the element. In terms of both chemically and physically.
Lead sulfate is produced as a lead acid battery is discharged. Hope this helped!
Answer:
The ball hit with 12 N
Explanation:
acceleration = Force/ mass
If masses of balls are the same, then more the force - more acceleration.
12N more than 8N,
so the ball that hits Stacy accelerate faster.
