If in space with no opposing force,will a body of 1 kg pushed with 1 N force keep on accelerating 1 m/sec every second? When will it stop accelerating?
I don't understand the fact that let's say hypothetically I was pushing a block on a frictionless surface, and I kept applying the same force on the object how it would keep accelerating! Wouldn't there have to be a certain velocity where it would stop getting faster? If not then what is actually acting on the object to cause it to accelerate infinitely?
I opened terminal windows and I got a message   your screen size %d%d is bogus. Expect trouble   I closed the terminal and the next time I opened terminal, the message didn't show up.   What is this message and why did I receive it? How do I set Windows to boot as the default in the boot loader? How do I set the bootloader so that in my dualboot with Windows 7/Ubuntu 11.04, Windows start up as standard instead of Ubuntu? How are reviews assigned? I accidentally opened Orca Screen Reader from the Dash when I was trying to open Screenshot. Now everything I type or click on is spoken out loud.  How do I make it stop?  For reference, here is a screenshot of Orca Screen Reader running: Proving an entire, complex function with below bounded modulus is constant. How would I show that an entire function $f$ with the property $|f(z)| \geq 1$ must be constant?    I'm aware of Liouville's theorem, just not sure how to apply it here. Regular Expression: Numeric range string str1 = "12345ABC...\\...ABC100000";   // Hypothetically huge string of 100000 + Unicode Chars  str1 = str1.Replace("1", string.Empty);  str1 = str1.Replace("22", string.Empty);  str1 = str1.Replace("656", string.Empty);  str1 = str1.Replace("77ABC", string.Empty);   // ...  this replace anti-pattern might happen with upto 50 consecutive lines of code.   str1 = str1.Replace("ABCDEFGHIJD", string.Empty);   I have inherited some code that does the same as the snippet above. It takes a huge string and replaces (removes) constant smaller strings from the large string.  I believe this is a very memory intensive process given that new large immutable strings are being allocated in memory for each replace, awaiting death via the GC.  1. What is the fastest way of replacing these values, ignoring memory concerns?  2. What is the most memory efficient way of achieving the same result?  I am hoping that these are the same answer!  Practical solutions that fit somewhere in between these goals are also appreciated.  Assumptions:    All replacements are constant and known in advance Underlying characters do contain some unicode [non-ascii] chars Is the Discrete Topology on $X$ the Only One Containing All Infinite Subsets of $X$? Prove or find counterexamples.  Let $X$ be an infinite set and $T$ be a topology on $X$. If $T$ contains every infinite subset of $X$, then $T$ is the discrete topology. What's the best way make an "augmented" coefficient matrix? When studying systems of linear equations, it's nice to remind people that the last column of the coefficient matrix holds the constants.  This is often done in books by putting a vertical line between the last column and the next to last column.  What is a good way to do this in LaTex? Is it possible to produce a context free grammar for Tikz path? node? Even further, I would be happy to see a definition of the tikz language in the usual manner programming languages such as Java and Pascal are defined.   The reason I ask is that I keep getting mysterious error messages for the tiniest typos. Essentially, incorrect use of the underlying languages leads to a "crash" of the compiler. This crash sometimes gives useful error messages, but sometimes they are hard to decipher. RSA encryption with private key and decryption with a public key Does a bad grade in one course (with otherwise OK record) affect graduate admissions? I'm currently an M. Phil student in Math and I failed a course last semester because I was not able to hand in a home work assignment (which was worth 40% of my grade) on time (I was 30 minutes late).   Apart from that I'd say I'm a fairly decent student, I got an upper second class honours bachelors degree, I have a B+ and A's for all my other courses in my current programme and I'm almost finished with my first paper to be published.   I've however been deeply worried about this failure as it would reflect poorly on my transcript if I were to apply to a Ph.D or another Master's programme.   Will my failing grade affect my chances of getting into a competitive programme or greatly lower my chances of getting a scholarship? When will my device get the Android 5.1 update (Lollipop)? Android 5.1 (Lollipop) was officially announced on March 9th, 2015.  You can review the high-level changes at the announcement on the official .  Of course, not all devices will get this update right away and others won't get it at all. Each manufacturer and carrier often choose to add their custom modifications which tend to delay the official release.  When will each device get Android 5.1, either officially or unofficially, if ever?  See also: Message appearing when a user was removed.

Is it possible to calculate the sum of polygon areas based on whether or not it has a value in another column?   For example:  In column 2 I have the area of polygons. I want to calculate the area of all polygons that contain 'AG' in column 1 or all polygons that are IN column 1. But calculate them separately so I can get the total area of each type in column 1.
