Aspaceship in our solar system emits a red light that is visible from earth. as the spaceship moves away from earth, light is no longer visible from the spaceship. which of the following could explain this? the light can't reach earth because the spaceship is moving away from earth so quickly. b. the light can't reach earth because the spaceship has passed behind a nearby star. c. the light has been shifted into the longer-wavelength, infrared section of the light spectrum, which is not visible. d. the light has been shifted into the shorter-wavelength, ultraviolet section of the light spectrum, which is not visible.

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?

Anybody wanna ? (picture included? )

Question 1 (5 pts): what is the maximum distance for which you can you resolve the two individual headlights of an on-coming truck as two separate lights rather than one if the headlights are separated by 2.00 m and your eye has a diameter of 1.00 centimeter? assume a wavelength of 500 nm.
