You are shadowing a nurse in the emergency room of a local hospital. An orderly wheels in a patient who has been in a very serious accident and has had severe bleeding. The nurse quickly explains to you that in a case like this, the patient's bed will be tilted with the head downward to make sure the brain gets enough blood. She tells you that, for most patients, the largest angle that the bed can be tilted without the patient beginning to slide off is 32.0 degrees from the horizontal.

a. on what factor does this angle of tilting depend?
b. find the coefficient of static friction between a typical patient and the bed's sheets.

This problem is giving me trouble.
Please help me to understand it.

Please mark each part to the question to avoid confusion.

okay these are my math riddle we had to make and it has to be REALLY HARD. that the teacher cant find out. okay let me see if you can figure these TWO riddles out.

RIDDLE 1)
This number has 4 places to the right of the decimal point. It has 2 hundreds,3 ten thousanTHS, and 1 tenTH. It is in between 240 and 242 The thousandTHS place is one less than the ten thousandsTHS and less than the hundredTHS.What are six numbedrs that math the data?

RIDDLE 2)
This number has a 0 in the ones place. The fifth digit to the righr of the decimal sign is less than the first. The number in the thousandTHS lace is the smallest number.The number in the ten thousantHS place is half the value of the number on the hundreDS place. This decimal contain a 4,2,1,3 and 5.What is the number?

A soda glass has the shape of the surface generated by revolving the graph of y=6x^2 for 0<=x<=1 about the y-axis. Soda is extracted from the glass through a straw at the rate of 1/2 cubic inch per second. How fast is the soda level in the glass dropping when the level is 3 inches? (Answer should be implicitly in units of inches per second. Do not put units in your answer. Also your answer should be positive, since we are asking for the rate at which the level DROPS rather than rises.)

Any suggestions?


Thanks

I have heard that cell phones pick up the signal from the nearest cell tower and as you move you switch from tower to tower. But let's say that I'm travelling really fast within the coverage of a single tower, like on a military fighter jet or something like that. Does that tower's coverage just cover the area and if you're within that geographical region you'll get a signal no matter how fast you're travelling throught it?

In my lab class, we did a flame test using a bunch of different metal ions. Of all of the metal ions we tested, Na gave the brightest color and burned the longest (it was a bright orange). Do you think that potassium (it was a whitish-purple) could be detected by the human eye in the presence of Na by burning the two in a flame?
