I have an Iphone 4s and the rear camera wont focus close up and is blurry whenever I take photos. the reason for this is because there is a black piece that is blocking half the lens and I don't know what this is... Does anyone know what the black piece blocking my rear lens could be? It seems as if i dropped it and a piece feel down. Can this be fixed if I buy the tools to take my phone apart? The phone is no longer under warranty.

Thanks

Suppose you use Newton's method to locate t starting with b as an initial guess. Let u = b - f(b) / f ' (b) denote the first approximation supplied by Newton's method.

Which of the following are true? ( indicate all that apply)

1) u>b

2) u<b

3) u>a

4) u<a

5) u>t

6) u<t

7) impossible to determine

Does anyone know where I can buy a 30volt Ametek motor that isn't on ebay for a fair price? or maybe a motor that is very similar to an 30volt Ametek motor? I am buliding a homemade windmill and I need something that puts out 12 volts at a low RPM. Thank you!

When using a candlestick chart how do you tell where the resistance and support are of a stock? i've been trying to figure this out but haven't found any good examples.

put like variables on same side. do I muliply (1/2) by 2x and -6?

I changed my wheel hub assembly yesterday and put everything back together. When I pulled the car out of the shop and started driving the wheels seem to be making a chirping noise... It can't be the wheel bearing because i just changed them. My brake pads are wore on one side due to the caliper sliders sticking. so i'm going to grease them. does anyone know what the noise could be? it makes the noise just riding along and not stepping on the brakes.

I have insurance through verizonn "Asurion", I was wondering if I lost my phone and got a new one and then found my phone later on if I have to send it back to the insurance company or keep it?

I Have a Lg 32" LE5300 tv and it shut off while watching it and won't turn back on. This happened two other times and they replaced the power and Main board in the tv. Does anyone know what is going on with the tv? I have it plugged into a surge protector and I don't abuse it.

A hollow steel ball weighing 4 pounds is suspended from a spring. This stretches the spring 1/7 feet. The ball is started in motion from the equilibrium position with a downward velocity of 6 feet per second. The air resistance (in pounds) of the moving ball numerically equals 4 times its velocity (in feet per second) .

Suppose that after t seconds the ball is y feet below its rest position. Find y in terms of t. (Note that the positive direction is down.)

Take as the gravitational acceleration 32 feet per second per second.

A steel ball weighing 128 pounds is suspended from a spring. This stretches the spring 128/401 feet.

The ball is started in motion from the equilibrium position with a downward velocity of 5 feet per second.

The air resistance (in pounds) of the moving ball numerically equals 4 times its velocity (in feet per second) .

Suppose that after t seconds the ball is y feet below its rest position. Find y in terms of t. (Note that this means that the postiive direction for y is down.)

y=?????
