QC A rocket is fired straight up through the atmosphere from the South Pole, burning out at an altitude of 25km when traveling at 6.00km / s. (a) What maximum distance from the Earth's surface does it travel before falling back to the Earth? volvulus requires ultrasonography to untwist the loop of the bowel. group of answer choices true false how many atoms are contained in a 4.65 g sample of the (atomic mass = 4.003 g/mol)? An object is tossed vertically upward from ground level. Its height s(t), in feet, at time t seconds is given by the position function s=16t 2+144t. n how many seconds does the object return to the point from which it was thrown? sec QC During periods of high activity, the Sun has more sunspots than usual. Sunspots are cooler than the rest of the luminous layer of the Sun's atmosphere (the photosphere). Paradoxically, the total power output of the active Sun is not lower than average but is the same or slightly higher than average. Work out the details of the following crude model of this phenomenon. Consider a patch of the photosphere with an area of 5.10 10m. Its emissivity is 0.965 . (d) Find the average temperature of the patch. Note that this cooler temperature results in a higher power output. (The next sunspot maximum is expected around the year 2012.) AB-52 bomber is flying at 11,000 m. It has eight turbojet engines. For each, the outlet port diameter is 70% of the widest engine diameter, 990mm. The pressure ratio is 2 at the current state. The exhaust velocity is 750 m/s. If the L/D ratio is 11 and the weight is 125,000 kg, what total mass flow rate is required through the engines to maintain a velocity of 500mph? Answer in kg/s Stocks, bonds, options, and futures are the four major types of:a. Debtb. Real assetsc. Equityd.

All of the following difficulties are associated with the use of PERT EXCEPT: Group of answer choices It often requires more effort to generate three estimates than one. It highlights uncertainty in project duration It does not accurately address the case when two activities both need to be accomplished before a third can begin. There is no assurance that three estimates are any more accurate than one In order for cells (plants or animal to create ATP energy molecules that allow the cells to do the important work of keeping an organism alive, they need to further break down the macromolecules in the foods they eat nurse is providing teaching to a client who has tuberculosis. Which of the following is appropriate for the nurse to include in the teaching 250.0 mg of copper(II) sulfate pentahydrate (CuSO4 5H2O, 249.70 g/mol) was dissolved in water to make 10.00 mL of solution. Of that solution, 2.00 mL was used to make a new solution with a total volume of 250.0 mL. What was the concentration of the copper ion in the final solution? In order to pay for college, the parents of a child invest $20,000 in a bond that pays 4% interest compounded semiannually. How much money will there be in 20 years? Round your answer to the nearest cent. In 20 years the bond will be worth S.
