Ga ray of light impinges from air onto a block of ice (n 1.309) at a 60.0 angle of incidence. assuming that this angle remains the same, find the difference 2, ice 2, water in the angles of refraction when the ice turns to water (n 1.333).

An astronaut floating in space is trying to use her jetpack to get back to her space station, but she is being pulled away by a nearby planet, as shown in the image below. her jetpack provides a constant thrust of 310 n. if she angles her jetpack in such a way that it cancels out the vertical force due to the planet's gravity, what is her net horizontal force? thaud 487 o a. 54.8 n toward the space station o b. 212.9 n toward the space station o c. 185.2 n toward the space station o d 956 n toward the space station
