What is the square root of 1023? (Hints: 10 is an integer number. Integer numbers are exact, they don't have any uncertainty. The result however is going to be a real number. Computers approximate real numbers using floating point numbers. Floating point numbers have a given number of significant figures or digits. LON-CAPA typically expects 3, 4 or 5 digits. 2 or 1 is not enough, 6 or more is too many. Very large or very small numbers are expressed in scientific or exponential notation like the number above. Numbers in scientific notation are entered to computer software - like LON- CAPA as 1.23E15 or 1.23e15, for example; and 1.23E-15 or 1.23e-15, if the exponent is negative. If both the number and the exponent are negative, then you type -1.23E- 15 or -1.23e-15. On calculators the button is usually labelled as 'EE', but 'E' or 'EEX' or 'Exp' are also possible.)

A hot tub with a surface area of 28 ft2 is filled with water to a depth of 29 in . Hint: volume is calculated as area × height (A × h). A) What is the volume of water in the tub, in liters? Express your answer to two significant figures and include the appropriate units. B) How many kilojoules are needed to heat the water from 59∘F to 103 ∘F? Express your answer to two significant figures and include the appropriate units. C) If the hot-tub heater provides 5900 kJ/min, how long, in hours, will it take to heat the water in the hot tub from 59∘F to 103∘F? Express your answer to two significant figures and include the appropriate units.
The consumption rate of electricity, in kW/h has increased, on average, at 4.5% per year. If it continues to increase at this rate indefinitely, find the number of years before the electric companies will need to double their generating capacity The electric company will need to double their generating capacity about every years. (Do not round until the final answer. Then round to the nearest tenth as needed)
I need help with a University Physics 1 (significant figures) - The problem is described in the image below:
Hey, I'm really so sorry for leaving this out, but I completely forgot to tell you that I need the answer in the amount of years it takes. That's totally on me, I apologize. Also, I can't tell if the dot between the two 2s in the answer is a multiplication symbol or a decimal point.
