A bicycle can be used to generate electric power by attaching a loop to the axle and letting it rotate in a magnetic field. Suppose such a device is attached to a bicycle with a 65 cm diameter wheel.
(a) What is the velocity (in m/s) of the bicycle if the generator's angular velocity is 63 rad/s?
(b) What is the maximum emf of the generator when the bicycle moves at 3.5 m/s, noting that it was 17 V under the original conditions?

answercollision;

the given statement is true.

sensory memory lasts for a fraction of seconds before the information is lost. it is the shortest -term memory and can be called as an element of memory. example: when we look at something and remember what it looks like, is just a second of observation. it degrades very quickly. it can also be considered as the process of perception rather than considering it as a memory.
