can attain a centripetal acceleration 1.5 times the free-fall acceleration. If the falcon is flying at 20 m/s, what is the radius of the turn?

Can anyone help me with this physics problem? Please don't just tell me the answer, I want to see how it's done!

Here's the question:
Explain why there are two high tides and 2 low tides each day.
i get the whole gravity pull thing, but wouldn't there only be one high and low tide per day? would the earht need to rotate a second time for a second tide?

As in: A car is capable of accelerating at a uniform rate of .85m/s2. What is the magnitude of the car's displacement as it accelerates uniformly from a speed of 83km/h to one of 94 km/h?

Please correct wrong steps in my chain of thought: I started by changing .85m/s2 to km/h by multiplying the entire thing by 1000/3600. Then I got stuck as I didn't know what magnitude of displacement was. Is it a measurement in m/s. Or seconds? Or metres?

8 chips in bowl, 3 which has the number one, 2 which have the number 2 and 3 which has the number 3. the probablility of drawing each chip at random is 1/8. let random variable X is S={1,2,3} finda the probablility assignments for these three outcomes and find the mean and variance for these probablility assignments.

I am confuse as to how to approach and solve this question thanks for any help.

three ballot boxes are connected by cords, one of which wraps over a pulley having negligible friction on its axle and negligible mass. the three masses are mA= 30kg, mB=40 kg and mC=10kg. when the assembly is released from rest:
a. what is the tension in the cord connecting B and C
b. how far does A move in the first 0.250 s
could you help me figure out the right equations to use?
thanks.

I asked this previously under a different subject title, and I got little in the way of helpful responses. Can someone tell me what type doc I should see for shingles? I've was diagnosed by my gp, but I don't feel he is totally ethical in his approach to things. I need to know, do I check into seeing a neurologist? Dermatologist? Please, someone -- anyone, can you be of some assistance? If you answered under another subject, please don't repost the same answers. I need a new set of helpful answers.

My teacher always talks about how to easily find out what numbers divide into other numbers, like adding the sum of the even and odds and finding out what that number is, which divides into the original number ... I don't know if that is correct, but is there any way to figure out how to do this with large numbers? I am looking for relations in perfect squares, radicals, etc. Thanks :)
