show steps please.

Channel 5-1 on for my TV always seems to go out at 1am every night. It just says No Signal and it is pretty precise and on the dot 1AM. I was just wondering why it is like this and if anybody else is experiencing a similar problem.

I was just wondering what it was called when a bunch of people, hundreds or maybe thousands get together and just do synchronized motions that look very cool from above

if anyone know what I'm talking about (just read it myself and it looks very vague and confusing..) could they send me some links of videos of it or I could youtube it if I got the name of this

I am planning on getting the front of my house fixed up. I am complete brick cleanup(cleaning, picking), removing about 100-150 bricks and replacing them, and cleaning up front of the roof ledge.

How much do you think this would cost and what exactly should I do when calling a contractor. Any tips or precautions I should take since I have never called a contractor to work on my house before.

was wondering when a group of people do walks for a good cause, how exactly does it help that cause when we walk a certain distance

In the ABC show What would you do. What exactly happens when the people contact officials like calling 911 , Also I wanted to know how real this show is

There are 50 students that enrolled in Math class, 33 students in Science class. There are 13 students enrolled in both. What is the total number of students?

If you see something that doesn't seem right, it might be since I don't have exact question in front of me.

Almost every other day, when I try to connect to wi-fi on my ipod touch, it doesnt connect and the little circle that kind of rotate(means it is loading) stays there and never leaves. When this happens I am unable to connect to wifi until i reset my network settings, BTW this seems to only happen when I connect to my school's network.

A charge of 3.36 μC is at the origin and a

second charge of −2.87 μC is on the positive

x-axis 0.910 m from the origin.

The Coulomb constant is 8.99 ×

10^9 N · m2/C2.

Find the magnitude of the electric field at a

point P on the y-axis 0.524 m from the origin.

Answer in units of N/C.

I figured that I could use the formula:

Fe = (kq1q2)/r^2

but after I get the electrostatic force, I tried to use:

E = Fe/q

but I don't see how I can get the answer

Fe = electrostatic force

E = electric field strength

q = charge

k = Electrostatic constant = 8.99E9

r = distance between charges

Can some help me prove this identity

sinA

------------- - cotA = cscA

1 - cosA
