Suppose two particles are thrown towards an object in the opposite direction, as illustrated in the figure below. The velocity of the particles relative to the object are measured as v1 = 0.6c and v2 =' -0.8c. What is the object's speed, relative to each of the particles?

Which process is represented by the pv diagram? a. the isobaric process b. the isovolumetric process c. the isothermal process d. the adiabatic process

In a system, when potential energy decreases, then entropy also decreases. true false

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?
