Compare the magnitude of Earth's rotational momentum about its axis to that of the Moon about Earth. The period of the Moon's rotation about Earth is 29.5 days, the mass of the Moon is 7.35×1022kg, the radius of the Moon's orbit is 3.84×108m, Earth's mass is 5.98×1024kg, and Earth's radius is 6370 km.

He viscosities of several liquids are being compared. all the liquids are poured down a slope with equal path lengths. the liquid with the highest viscosity will

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?
