(a) human eyes detect only a very small band of the electromagnetic spectrum. however, some animals and insects see in higher and lower frequency bands than humans do. for this discussion, first do some research to find three examples of animals or insects that see in higher or lower frequency bands. then, in your initial discussion post, address the following: what were the examples that you found? did they see in lower or higher frequency bands? list the specific wavelengths used by the animals/insects you chose. were you surprised by the information that you found? why or why not? (b) in your initial discussion post, identify the pros and cons of using mirrors versus lenses in each of the following applications: a large, ground-based, astronomical telescopea small "spy" scopea terrestrial telescope designed only to read license plates

Tall pacific coast redwood trees can reach heights of about 100 m. if air drag is negligibly small, how fast is a sequola cone moving when it reaches the ground f it dropped from the top of a 100 m tree?

A2000 kg car is rounding a curve of radius 200 m on a level road. the maximum frictional force the road can exert on the tires of the car is 4000 n. what is the highest speed at which the car can round the curve?
