Part C: Your friend keeps track of his gas mileage and finds that on average his car uses 20.79488098 miles per gallon (mpg). He has a 15 gallon tank and confidently tells you his vehicle will be able to travel exactly 311.9232147 miles on a single full tank of gas. Explain why you think such a level of precision is absurd.

Please do this carefully.

Head or tails Context To play heads or tails, you toss a 25 cent coin in the air straight up. To make sure you don't hit the ceiling, you want to predict the maximum height the room will reach, taking into account uncertainty as well. Constraints The initial height of your hand is fixed, and accompanied by uncertainty;The gravitational acceleration used will be ?=(9.81±0.01)m/s^2;The movement is perfectly vertical. Modelization Start by modeling the situation by writing an equation that calculates the maximum height reached by the coin (ymax) based only on the initial speed of the throw as well as the height of your hand when you throw the coin. Then test your model with the following values: Height of your hand = (1.01±0.02)m; Speed ​​of the coin when it leaves your hand = (2.17±0.04)m/s;

how do I convert a Newton*meter/meter^2 to Newton/meter^2 I figured out that I divied by 1000 but I dont understand how the units cancle my actual numerical answer is  266240Nm/m^2 and the correct answer is 266.24 N/m^2

I have already submitted this question and was given incorrect answers. I really don't understand how to work these problems out.  For part A I was told 1.8*10^29 Part B 3* 10^17 sec then I stopped trying because I lose 3% of points everytime I submit an incorrect answer.  Is this more of a logical quesiton or is there a formula to use?

་ Part A A starship voyages to a distant planet 10 ly away. The explorers stay 4.0 yr, return at the same speed, and arrive back on earth 26 yr after they left. Assume that the time needed to accelerate and decelerate is negligible. What is the speed of the starship? Express your answer using two significant figures. = 0.91 Submit Previous Answers Part B Correct Important: If you use this answer in later parts, use the full unrounded value in your calculations.

Hi could I have some asistance with the following question, could you please explain step by step of how to solve it so I can understand how to work it out, if you cant do it step by step please dont answer, thank you in advance: Two cars are travelling on horizontal roads in straight lines, car A at 90 km-h-1 at N 10\deg E and car B at 60 km-h-1 at W 60\deg N.Determine, by scaled graphical method, the velocity of car A relative to car B.

General remarks: • If you want to add scientific notation, as an example, 5×10-9, use the following way: 5*10^(-9) Or use this tool • DO NOT ADD ANY UNITS OR SYMBOLS WITH YOUR NUMERICAL ANSWERS
