You are on a team that is developing a game about people in outer space. You are using a computer program to create the sounds that will be used in the game. To make the sounds on your computer you have to change the characteristics of sound waves. Graph 1 shows a sound (one note) you are working on. 1. One way you can change the sound is to increase or decrease its frequency. Which of the graphs below shows how Graph 1 would change if you increased only the frequency of the wave? Graph . The following graphs (Graph 1 and Graph 2) show two different graphs for the same note.

In a simplified model of the human eye, the aqueous and vitreous humors and the lens all have a refractive index of 1.40, and all the refraction occurs at the cornea, whose vertex is 2.60 cm from the retina. what should be the radius of curvature of the cornea such that the image of an object 40.0 cm from the cornea’s vertex is focused on the retina?

3. a worker pushes a 30.5 kg polished stone along a polished table with a force on bonin a straight line for 5.20 s after starting from rest. there is no friction between thestone and the table. at the end of the table. the stone is hooked to a cable with a lengthof 62.0 cm to rotate it to a rough table to store until they can be picked up. the roughtable has a coefficient of static friction 0.702 with the polished stone. remember that 8= 9.80 m/s2a) what is the speed of the stone when it is hooked to the cable? b) what is the tension in the cable while the stone is rotating? (there is still nofriction)c) how much force is needed to make the stone begin sliding from rest on therough table? ius = 0.70262.0 cm30.5 kg20.5 kg6= 0
