Radiant energy travels in the form of electromagnetic waves. They are called electromagnetic waves because they contain both an electrical field and a magnetic field. Radio waves and light waves are examples of electromagnetic waves. Unlike mechanical waves such as sound, electromagnetic waves can travel in space. Which statement describes how electromagnetic waves and sound waves are alike?
Both types of waves are mechanical waves
Both types of waves transfer energy
Both types of waves can travel in space
Both types of waves have an electrical and magnetic field

An athlete swings a ball, connected to the end of a chain, in a horizontal circle. the athlete is able to rotate the ball at the rate of 8.13 rev/s when the length of the chain is 0.600 m. when he increases the length to 0.900 m, he is able to rotate the ball only 6.04 rev/s. (a) which rate of rotation gives the greater speed for the ball? 6.04 rev/s 8.13 rev/s (b) what is the centripetal acceleration of the ball at 8.13 rev/s? m/s2 (c) what is the centripetal acceleration at 6.04 rev/s? m/s2
