Problem 2 the james webb space telescope, the telescope that will replace the hubble, has a primary mirror that is concave with focal length with magnitude |f| = |131.4m|. what is the radius of curvature of the mirror with the correct sign? select one of the following: (a) 0m (b) +65.7m (c) −65.7m (d) +131.4m (e) −131.4m (f) +262.8m (g) −262.8m

According to newton's second law, when the same force is applied to two objects of different masses, a the object with greater mass will experience a great acceleration, and the object with less mass will experience an even greater acceleration, b. the object with greater mass will experience a smaller acceleration, and the object with less mass will experience a greater acceleration, c. the object with greater mass will experience a greater acceleration, and the object with less mass will experience a smaller acceleration, d. the object with greater mass will experience a small acceleration, and the object with less mass will experience an even smaller acceleration.
