Compare the visible part of the ear to a satellite dish in terms of form and function.
I will be happy to critique your thinking on this.
WTF bobpursley? You are of no help to me on any of this! If I want you to "critique my thinking" I was ask you to, but no where in my question did I ask you to!
Liz,
You must understand that this is a "help" board with emphasis on the word help. This is not a "post your question and get your answer to fill in the blank board." We try to HELP you do your work but we don't DO it for you. (I note that Bob Pursley answered your first two questions and two out of three is not a bad average. You got two freebies and one you must do yourself. Not bad.) Regarding the ear post, surely you have seen a satellite dish. And you have seen diagrams of the workings of the ear (or at least you have books or can look in an encyclopedia to see how the inner part of the ear looks and works.) Then you put two and two together, compare the two, and write a paragraph or two to describe what you have learned from that comparison. The help you get on this board is directly proportional to the amount of work you put into it; i.e., the more work you show the more help you receive. We welcome your posts. We want you to come back. We want you to learn. But we don't want to do your work for you.
You will find your answer here:
(look under heading outer ear)

So many students are not experts at finding information on the www (perhaps not their fault). They simply don't know how to do an advanced search. I feel if you don't want to give an answer that it is best to give a website. This makes the student dig a bit. It also, I feel, makes them feel helped enough they can't really complain bitterly. Albiet, no system is without drawbacks.
Lead is a soft, dense metal with a specific hear of 0.028 kcal/kgcelcius, a melting point of 328 degrees celcius and a heat fusion of 5.5 kcal/kg. How much heat must be provided to melt a 250.0kg sample of lead with a temperature of 20 degrees celcius?????
calculate the potential energy of an object that has a mass of 110 kg and is 15 m high?
calculate the potential energy of an object that has a mass of 0.056 kg and is 150 m high?
calculate the potential energy of an object that has a mass of 15 lbs. and is 15 ft. high?
calculate the potential energy of an object that has a mass of 1556 lbs. and is 0.5 ft high?
How is any of this done?
To compare the visible part of the ear to a satellite dish in terms of form and function, you can analyze their similarities and differences.
Form:
The visible part of the ear, known as the pinna or auricle, is a flexible flap of skin and cartilage that is shaped to capture sound waves and direct them into the ear canal. It has a curved and concave shape with ridges and folds, which helps with sound localization. On the other hand, a satellite dish is a dish-shaped structure made out of metal or fiberglass. It has a concave shape that allows it to capture and focus radio signals from satellites.
Function:
The main function of the visible part of the ear is to collect sound waves in the environment and direct them into the auditory canal, where they will eventually reach the ear drum and be processed by the inner ear. The unique form of the ear helps in the localization of sounds and enhances the ability to differentiate between different sound frequencies.
Similarly, the main function of a satellite dish is to receive radio signals from satellites in space. The concave shape of the dish helps to focus the signals onto a receiver or feedhorn, which then amplifies and converts the signals into a usable form. The design of the dish ensures that it can capture signals from a specific direction, providing a clear and accurate reception.
In conclusion, although the visible part of the ear and a satellite dish have different materials and purposes, they share similarities in their form and function. Both utilize a concave shape to gather and focus external signals, whether it be sound waves or radio signals, for further processing and utilization.
