When Is an object Stationery? Velocity = 0 or Displacement = 0 ??
An object is stationary when its velocity = 0. Velocity is displacement divided by time, in m/s. If you've moved zero meters in some period of time, you are stationary. Displacement = 0 does not imply that an object is stationary. As an example, an object could be moving with a velocity of 10 m/s, and at some instant in time, could have a displacement of zero from the origin of your coordinate system. Here's an example: pick the start/finish line on an oval racetrack as displacement = 0. When the cars speed across that line, their displacement = 0 but their velocity does not.
How can I use a scanned stationary paper to write on my pc with microsoft word?
I have a certificate stationary paper with borders. I would like to scan this paper and use it as a template where I can write, copy and paste on it with microsoft word. thanks in advance
What can a stationary bike do for my legs? and my butt? will it make m legs tones and my butt firmer? or none?
Well it will do everything you said... Unless you eat more... So, if you burn 2000 calories naturally in a day..and exercise burning 500 calories, eat 2500 calories. Your butt will get firmer because you add muscle to it...as well as your legs. But, a girl's legs can only get so muscular. Those stationary bikes will work specifically on your lower-belly area as well.
Can someone please list all the stationery items i will need for back to school?
I'm going into year 9 as well and asked a similar question, for stationary, i guess it would be stuff like this: Black or blue pens Pencils Coloured pencils Ruler Rubber Sharpener Geometry set (compass, protractor, that triangle thing-magig) Calculator (best to have a scientific one) A folder for your homework you probably don't need books coz the school normally provides them. highlighters? Is it just stationary you want or other stuff like to put in your school bag? =D I'm bored right now so I'll tell you other stuff as well that I put on my list ready for September! Umbrella Lipbalm Deoderant Pads (if uve started or you know you soon will) spare socks (knowing the weather these days.. especially where I live lol) Some tissues and u might want some gum or mints or somethin like that =)
Motorcycle hits opened door in stationary traffic?
Okay, so here is the situation: I live in California where it is legal to filter/lane split through traffic IF done SAFELY (not swerving in and out of traffic at 60mph). A few nights ago, I was coming home from work on the interstate where it was backed up with bumper-to-bumper traffic. Since the cars were moving excruciatingly slow or not even moving, I decided to filter in between two lanes at 15mph average, never going over 20mph, and keeping my hand on the brake handle and watching out for any cars doing any crazy maneuvers or trying to cut me off just because they are pissed (happened to me before). I come to these two cars parallel to each other, not moving, when the driver of the right-hand car suddenly opens his door. I stop, honk my horn, and raise my hands in disgust/confusion. As I pass the car, I notice that the driver of that car still had his seat belt on, so why the hell would he need to open the door all the way if he doesnt intend on getting out or anything. Long story short, if a motorcyclist is in my situation and DID hit the door, who would be at fault? Which insurance pays the damage? I mean, I can claim that the driver was doing it out of spite/road rage, but I would just be assuming things.
Here is a Physics question. In a crash is it better to be stationary or moving forward?
(Answer based on Conservation of momentum)Honestly all that matters here, is the relative velocity between two crashing objects.If one vehicle moves toward you while the crashing, it will obviously be safer to stay stationary (or move away, if possible) than moving forward towards it. This is obvious via intuition. Basically the relative velocity of approach should be minimized as much as possible.But for 2 identical vehicles, the effect on both vehicles will practically be the same, even if one was stationary, so that's that. The only advantage you can gain, is by having the heavier vehicle among the two.
Prop produces most power when aircraft is stationary?
I see where you are going with the Helo comparison. The fault in your logic is that the Helo doesn’t so much rely on displacing air downwards to fly as a fixed wing displaces air aft. The rotary wings (as Igor Sikorsky called them, a more accurate term than rotor blades) work more like the wings of your light a/c than the propeller. They generate lift by moving air over them as they rotate. This is why translational lift is greater. The speed of the air over the rotary wings increases with increased forward velocity. Therefore more lift is generated. Notice we call it lift not thrust.
Question on re-creating Harry Potter's Hogwarts Invitation letter. Can you help?
I am trying to recreate the Hogwarts invitation letter and envelope (As close to the movie version as possible). I'm almost there but need some questions answered before that is possible. Hope you can help. Here is a reference picture: http://www.curiousgood.com/?page_id=333 Here are the questions: 1. What size is the Envelope? And where can I find these envelopes? In particular I am looking for the Die Cut versions with the special shape on the back. 2. Where can I find that particular (the one pictured) Hogwarts crest/logo? Searching online has produced no results on this exact image. It is a more simple version without much detail to the house creatures. If anyone knows of a link I would appreciate it! I have the Wax Seal, Calligraphy set with Emerald Ink etc... Once these questions are solved I will be ready to make my letter. So for all you prop re-creators please help me! Thanks!
