The tire of your bicycle needs air so you attach a bicycle pump to it and begin to push down on the pump’s handle. if you exert a downward force of 25.0 n on the handle and the handle moves downward 0.500 m, how much work do you do?

Rank the torques on the five doors shown in the figure above from least to greatest. note that the magnitude of all the forces is the same

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?

Which is an example of an exothermic process?
