The magnification of an object is defined as m=h′h, where h′ is the height of the image and h is the height of the object. if the image is inverted, then h′ is negative. place the pencil 90 cm from the lens. what is the magnification of the image (be sure the curvature radius is still 0.6 m and the refractive index is 1.5)?

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
