An olympic athlete set a world record of 9.58 s in the 100-m dash. did his speed ever exceed 37 km divided by hr during the race? explain. select the correct choice below and fill in any answer boxes to complete your choice. (round to one decimal place as needed.) a. the average speed is nothing km/hr. since this value is below 37 km/hr, it is impossible to tell if his speed exceeded 37 km/hr. b. the average speed is nothing km/hr. by the mean value theorem, the speed was exactly nothing km/hr at least once. by the intermediate value theorem, all speeds between nothing and nothing km/hr were reached, therefore the athlete's speed exceeded 37 km/hr. c. the average speed is nothing km/hr. by the mean value theorem, the speed was exactly nothing km/hr at least once. by the intermediate value theorem, all speeds between nothing and nothing km/hr were reached, therefore the athlete's speed never exceeded 37 km/hr.

the temperature in kelvin of 2.0 dm3 of an ideal gas is doubled and its pressure is increased by a factor of four. what is the final volume of the gas

russian is not my first language, so i'm afraid i can't write out an answer in russian, but hopefully you can find a way to do so. here's my best translation of the problem: you're given a plot of a particle's position in one-dimensional space over time, and you're asked to find either the total distance traveled by the particle after 6 seconds had elapsed, or the total displacement of the particle after 6 seconds.

if you want the total distance traveled, you would first need to determine the particle's velocity as a function of time, then integrate that over the 6-second interval. we know the position function is quadratic with roots at 0 and 6, so we have

where is unknown. because the position is parabolic, there is symmetry about the midpoint at , and we know that

so that the position function is

which means the velocity is

then the total distance traveled is

so the total distance traveled is 20 m.

on the other hand, if you want to find displacement: the particle starts at and ends at , so its displacement is 0.

because if the tool that you are using is not balanced it there would be false mass.
