Its a simple question.

You are going to design a new roller coaster ride a theme park. The park wants you to be sure to

put a loop in the roller coaster that will thrill its riders. Your job is to find out the radius of the loop

for your roller coaster if your riders are going 22 m/s when they are at the top of the loop and they

are to experience a moment of "weightlessness" when at the top of the loop.

Ok. I need to solve this equation for theta θ but I have not been unable to successfully do it. I know the answer is about 51 degree from using a calculator but I still need to work it out long hand. Thanks.

130 * sinθ - 89.7 * cosθ - 45 = 0

Can someone help me with this physics problem.

2 cars are on opposite ends of a 5 meter course. Both cars leave the starting point at the exact same time heading toward each other. Car #1 travels at 0.519m/s and car #2 travels at 0.506m/s.

Where will the collide? (Distance from either starting point)

Thanks.

How to I calculate the pH after a titration of 10.19mL 0.10M HCl with 10.99mL 0.093M NaOH.

I know how to calculate the pH of the acid and base before the titration but I am sure how to calculate it after the titration has taken please. I also know that it should be about 7 at the equivalence point but I need the calculated pH using my values.

How would I rationalize this expression?

( (1 / sqrt(3)) - 1)

---------------------------

(1 + (1 / sqrt(3) ) )

I have tried to do it but I can't seem to get the corect answer. Work would be helpful.

When solving a equation that contains trig functions, why can not divide a trig function?

ex. sinxcosx=cosx to sinx=cosx/cosx

I bought a Dell GX260 for a school installing new equipment. The computer will not boot when trying to boot from XP install cd. Every time it starts it shows the message "strike f1 to retry boot, f2 for setup". I have run the bios ide diagnostics and everything looks good. The hard drive will boot in another computer. All the internal connections look good. I have tried reseting the CMOS but it had no effect. There is a chance the CMOS battery my be dead because it has been sitting around for awhile. Is there anything else i can check?

The first being a fraction with zero in the denominator.

i.e. (x/0)

I know it can be done because I have done it before but just can't remember how.

I have the CG814wg gateway from Comcast. The problem is that it is hardwired with only 4 ip address. I need a way WITHOUT replacing the gateway to allow wireless connection to internet.

Would adding a router onto the gateway help?

What speed do you get with your EVDO card (wireless internet from a cellular provider)? Please include theaverage download speed, your carrier (Sprint, Verizon, etc.), and your location?

When i have headphones plugged into my sound card the sound come out almost as a whisper. I have the system sound at it's max. I am wondering if there is an relatively inexpensive hardware or software way to solve my problem.

Is it possible to share files and printer with a wired Ethernet router WITHOUT a broadband modem/connection

I am having a problem with Windows. In the folder right-click menu. The default is "Search" rather than "Open". So when i double click to open the folder it Searches. Help!!!!!!!!
