- doesn't that still need to be multiplied by 6?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) A typical small passenger electric vehicle has a range of 200 km on an electric charge of 33 kWh. Convert this number into J/km (Joules per kilometer traveled). b) A comparably sized gasoline powered vehicle to (a) is rated as 25 miles per gallon. Convert this number into J/km (Joules per kilometer traveled). c) If gasoline costs $10.00 per gallon, and electricity $0.30 per kWh what is the difference in the cost of fuel per kilometer travelled between the electric vehicle in (a) and the gasoline powered vehicle in (b)? d) Surveys of EV owners show that they charge at home 70% of the time. Let us assume that for the remaining 30% they charge at a 60 kW rated "fast-charge” station. If patterns of travel remain the same, but we swap all our gasoline vehicles for electric vehicles, what is the ratio between installation of fast charging stations to gasoline pumps retired. e) The Chicago Transit Authority has about 2700 buses that travel a total of 240,000 miles daily. A typical bus…
- 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.Thank you- what would be the unit for (f) if the number is 0?
