Answer:
The number A(t) of grams of salt in the tank at time t is
Explanation:
Knowing
First we have to find the Rin and Rout
Rin = (concentration of the salt inflow) * (input rate of brine)
Rin = 1 g/L * 3 L/min = 3 g/L
Rout = (concentration of the salt outflow) * (output rate of brine)
Rout = () * (3 L/min) =
Substituting this results
= 3 - -->
Thus, integration factors is
A(t) = 4
Applying the initial conditions
A(0) = 40
c = 150 - 40 = 110
Now, substitute this result in the solution to get
Answer:
the rope pulls the monkey upward with the same force
Explanation:
When the monkey pulls the rope exerts a force on it, in response the rope pulls the monkey upward with the same force, these two forces are action and reaction forces.
The characteristics of these forces are of the same magnitude. They are applied from the bodies involved and have opposite directions.
Therefore with the force of the rope the monkey climbs on it
I would have to say the answer it false
