If one end of a heavy rope is attached to one end of a light rope, a wave can move from the heavy rope into the lighter one. (a) What happens to the speed of the wave? It is constant. It increases. It changes unpredictably. It decreases. (b) What happens to the frequency? It increases. It decreases. It is constant. It changes unpredictably. (c) What happens to the wavelength? It decreases. It increases. It is constant. It changes unpredictably.

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?

As a pendulum bob swings back and forth several times, the maximum height it reaches becomes less and less. this is because more and more of the pendulum bob's energy is being transformed into a. heat energy b. kinetic energy c. potential energy d. kinetic energy and potential energy
