If you drink cold water, it will soon warm up to body temperature (about 37 c) this takes energy. therefore, you ought to be able to keep your weight down even if you eat fattening food provided you also drink lots of cold water, right? estimate what volume of cold water you would need to drink to overcome the effect of eating one chocolate sundae. (a chocolate sundae contains about 500 cal. recall that 1 cal, the "calorie" normally used in the us to measure the energy content of food, is 1000 cal, or 1kcal.)

Two identical 82 mg dust particles very far apart (pee 0) are moving directly toward each other at a speed of 3698 m/s. the charge on each is-719 ? c. determine how close they will get to each other. let k = 9x109 n-m2/c2 & ignore gravity.

In positive numbers less than 1, the zeros between the decimal point and non zero are significant

Very large accelerations can injure the body, especially if they last for a considerable length of time. one model used to gauge the likelihood of injury is the severity index ( ), defined as =/ . in the expression, is the duration of the accleration, but is not equal to the acceleration. rather, is a dimensionless constant that = the number of multiples of that the acceleration is equal to.in one set of studies of rear-end collisions, a person's velocity increases by 13.7 km/h with an acceleration of 36.0 m/s2 . let the + direction point in the direction the car is traveling. what is the severity index for the collision?
