b. draw a ray diagram to locate the image of the arrow, as refracted through the lens shown. write 2 - 3 sentences describing the type of image and its size relative to the object. what type of mirror could be used to form an image of the same type and size? (image attached)
c. an object is located 60 cm from a convex mirror with a focal length of 20 cm. what is the image distance? is the image real or virtual?

Acylinder with a movable piston contains 11.7 moles of a monatomic ideal gas at a pressure of 1.32×10^5 pa. the gas is initially at a temperature of 300 k. an electric heater adds 43200 j of energy into the gas while the piston moves in such a way that the pressure remains constant. cp=20.79 j k^−1 mol^−1 for a monatomic ideal gas, and that the number of gas molecules is equal to avogadro's number (6.022×10^23) times the number of moles of the gas. (a) what is the temperature of the gas after the energy is added? (b) what is the change in volume of the gas? (c) how much work is done by the gas during this process?
