Answer: Yes
Explanation:
Yes, i would invest in this idea, Because the procedure looks very lucrative. Because the initial extraction of the energy from the ground requires no fossil fuel to keep the device running or in operation, rather the heat extracted would be used to heat a heat pump which would boil into steam and in turn used to drive a or power a steam engine.

Answer:
<h3>Therefore, after long period of time 80kg of salt will remain in tank</h3>
Explanation:
given amount of salt at time t is A(t)
initial amount of salt =300 gm =0.3kg
=>A(0)=0.3
rate of salt inflow =5*0.4= 2 kg/min
rate of salt out flow =5*A/(200)=A/40
rate of change of salt at time t , dA/dt= rate of salt inflow- ratew of salt outflow
integrating factor
integrating factor
multiply on both sides by
integrate on both sides
b)
after long period of time means t - > ∞
<h3>Therefore, after long period of time 80kg of salt will remain in tank</h3>
