    Energy Income
AI Thread Summary
The discussion revolves around calculating the yearly income from selling 2.12 billion watts of energy at an industrial rate of 1.8 cents per kW-hr. The initial calculations attempted to convert watts to kW-hr and then estimate annual energy production. However, confusion arose regarding the correct conversion of energy produced per second to an annual figure. The correct approach involves recognizing that the energy produced every hour is 2.12 million kW-hr, leading to a significant annual income calculation. Ultimately, the focus is on correcting the unit conversions to accurately determine the total yearly income from energy sales.

If the utility company sold 2.12x10^9 W of energy that they produced every second at an industrial rate of 1.8 cents per kW-hr, what would be their yearly income from this source? Give your answer in dollars.

so what i was doing is this...i was converting from W-s to kW-hr

2.12E9 W-s x kW/1000w x 1hr/3600s=588.89 kW-s

then i found how many hrs in a year 1 yer x 365days/1yer x 24hr/1day=8760

then i took the product of the two to find the amount of energy produced hourly per year which i got 5158676.4

then i multipied that by $.018 (1.8 cents)

but my answer was wrong

please tell me what is not right

Was your answer like $92856. I think the units are tricky here. The energy production is 2.12x10^9 per second. Notice "per" . Which means every hr it produces 2.12x10^6 kw-hr.

yes that is what i got
 
so try omitting the division by 3600, and see if it is correct per the logic in my first post.
 
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
Thread 'Variable mass system : water sprayed into a moving container'
Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
