A resistor is wired to a battery in a circuit and dissipates a power P₁ as heat. A second battery, with the same voltage, is added in series with the first battery, leading the resistor to dissipate a power P2 as heat. How much does the resistor dissipate with two batteries, relative to with one battery, or in other words, what is the ratio P₂/P₁?

A certain solar collector can absorb 3500 Btu in 9.2 h. Another panel is added, and together they collect 70000 Btu in 7.4 h. How long (h) would it take the new panel alone to collect 70000 Btu?
The left side of this equation tells how much energy Q the cylinder gives to the water while it cools. The right side of this equation tells how much energy Q the water and aluminum cup absorb from the cylinder to warm up. Because it is the same energy, they are equal. What is known in this equation? Mcyl 411.7 g, malum 46.5 g, malum+water = 175 g Can you find: mwater =? g Twater = Talum = 20°C (water and cup of room temperature) 90°C, T; = 35°C (hot cylinder and cool "cylinder+cup+water" temperatures) Tcyl kCal Calum = 0.22, Cwater 1 (specific heat of water and aluminum, measured in units kg-°C What are we looking for is Ccul - How we find it? Plug all the numbers into the equation (1), Ccul will be one unknown which you can calculate from the equation. Important, convert all the masses from grams to kilograms! After you find Ccyl, compare it to known value for the copper 0.093(our cylinder is made out of copper). |Ceyl -0.093| % : · 100% 0.093
A family wishes to buy a 2020 Toyota Camry. The two options the consider are (a) a standard automobile with and SI engine that gets 34 mpg and costs $18,000; and (b) a hybrid automobile that gets 52 mpg and costs $32,000. On average, the family drives 16,000 miles each year ad gasoline costs $1.65 per gallon. Calculate: (Show your complete solution) The amount of gasoline each vehicle would use each year. Gasoline cost savings of hybrid over standard. Time in months it would take to make up the difference in vehicle cost with fuel savings.
