My brother has downloaded some app where he can get into my laptop mainframe and see exactly what im doing when im not in the room. My home screen shows up on his ipad and he can mess around and get it back to normal before i come back. Is there something i can download or install that will prevent him from getting in?

I haven't been out of the country lately, so do you guys face any major issues when travelling to non-Muslims states? Like at the airport? Or on the streets? Or at a grocery stores when you ask for Halal food?

In the US when the tragic event in Connecticut occurred the president choked up at his address. But why doesn't he get choked up when he orders the drones coming in Pakistan which kill unimaginable numbers of innocent men. women and children?! Don't say oh we give you aid so shut up, so are paying us to keep our mouths shut when you kill the children of Pakistan? Please explain to me how this works? Explain to me how sacrificing hundreds of innocent people for killing one terrorist is fair? It upsets me that the event in Connecticut occurred, but doesn't it upset you that the children killed here don't even get a proper funeral? Find another solution to terrorism, stop killing our people! Mr President you cry when your country's children die, yet you get a good nights sleep when you order the drones to attach innocent souls!!!!! US is a unfair, manipulative, sour country that has no morals and you keep put mouths shut with aid so that we say nothing!

The Earth may be assumed to be an isolated sphere of radius 6.4 × 10^3 km with its mass of 6.0 × 10^24 Kg concentrated at its center. An object is projected vertically from the surface of the Earth so that it reaches an altitude of 1.3 × 10^4 Km. Calculate, for this object,

1- the change in its gravitational potential,

2-the speed of projection from the Earth's surface, assuming air resistance is negligible.

PLeaseeeeee explain what formula is used and why with working!!! I really am clueless right now!!

Explain why values of gravitational potential near to an isolated mass are all negative?

Guys this is a 3 mark question with three lines given for the answer so if you give me an answer pleaseee make it small enough to fit those lines but extensive enough to get the 3 marks! PLeaseee and thank you!

People go through terrible things in life, I have gone through terrible things in life but every time i fell off the horse i always found my way back on, whether it be jumping back myself or someone helping me get there. But right now, I'm still laying on the ground wondering if I'll ever be able to figure it out. I can't concentrate on studies, my future seems to mean nothing to me, i worry time to time then i just don't care. I eat way too much junk food, I have gotten really fat, yet i can't convince myself that its time to loose weight. I stopped taking care of my hair or skin, i just seem so chill, but on the inside i feel I'm breaking. Well there i put it out there so if you have a remotely decent advice on your finger tips then type it in please.

A cylindrical piece of a soft, electrically-conducting material has resistance R. It is rolled out so that its length is doubled but its volume stays constant. What is the new resistance?

The answer is 4R but i don't know how ti get it, pleaseee answer!!

A man has a mass of 80 kg. He ties himself to an end of a rope which passes over a single fixed pulley. He pulls on the other end of the rope to lift himself up at an average speed of 50 cm per second. What is the average useful power at which he is working?

Pleaseee answer!!

A block of mass 2.0 Kg is released from rest on a slope. It travels 7.0 m down the slope and falls a vertical distance of 3.0 m. The block experiences a frictional force parallel to the slope of 5 N. What is the speed of the block after falling this distance?

Pleaseeee i have an exam!!!

A molecule of mass 'm' travelling horizontally with velocity 'u' hits a vertical wall at right- angles to its velocity. It then rebounds horizontally with the same speed. What is its change in momentum?

Answer is -2mu but i dont know how to derive it pleaseee help!!

A uniform meter rule of mass 100g is supported by a pivot at the 40cm mark and a string at the 100 cm mark. THe string passes round a frictionless pulley and carries a mass of 20g.

At which mark on the rule must a 50g mass be suspended so that the rule balances?

Please and thank you!

Two parallel plates, a distance 25mm apart, have a potential difference between them of 12 kV. What is the force on an electron when it is in the uniform electric field between the plates?

Please please answer quick! Thank you in advance!

A copper wire of cross-sectional area 2.0 mm^2 carries a current of 10A. How many electrons pass through a given cross-section of the wire in one second. ?

Please answer i have an exam in a while!!!!

The current in a component is reduced uniformly from 100mA to 20 mA over a period of 8.0s.

What is the charge that flows during this time?

Please answer!!! The answer is 480mC but i can't derive it, please work it out and explain, even if partially vague, a little help is better than no help!!!

I was watching the news and they were showing the heart broken Romney supporters actually in tears! Any of you republicans cry?

Just curious what made you come towards Islam? With so much hatred for Muslims these days, how did you know it was the right choice?

I haven't been able to follow the news much. Just wanted to know what Romney plans to do with Pakistan if he were to be elected. I know Obama is a fan of the drones that come flying in from no where, does Romney support that?

Im trying to be a good Muslim, but i just keep missing out the Isha and Fajr prayers and if i do then not on time. Any advice on prayer punctuality?

If you guys get to wear clothes we find inappropriate why can't we wear something you think is plain wrong? Some of us like to cover ourselves when going out, no one forces me, i hate how non-Muslims just assume Muslim women are forced to cover themselves. I am not, i just feel more comfortable.

Last time you guys got my question deleted so i won't add details this time.
