One student was adamant that the bag and its contents should have lost mass. She argued that a solid had changed to a gas; thus a loss in mass. How would you respond to this student?
A) She is correct; gasses have less mass than solids.
B) She is incorrect; the mass of the reactants equals the mass of the products.
C) She is correct; the mass of a solid plus water is more than a liquid plus gas.
D) She is correct; the gas is released from the bag resulting in less total mass.

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 statement best describes the superposition principle? a.) if two in-phase waves arrive simultaneously at a point, their amplitudes add up b.) if two out-of-phase waves arrive simultaneously at a point, their amplitudes add up c.) if two in-phase waves arrive at a point one after another, their amplitudes add up d.) if two out-of-phase waves arrive at a point one after another, their amplitudes adds up
