The fire alarm at my school scares me so bad. When I'm sitting in class, I just feel trapped. I can never stop wondering, when is it going to go off, when is it going to go off? It has gotten so bad that I've actually had to email the principal and ask for the school fire drill schedule. However, I still worry that somebody could burn something in the kitchen, accidentally pull it, etc. I've been terrified of the alarm since third grade. It has definitely interfered with my school life waaaay to much, to the point where it makes every single school day hell. I worry about other things too, but not so much as I worry about the fire alarm. I know this sounds stupid, but I need help. How can I help myself?
once you're in London there's a place you incredibly ought to pass to to get advice and a hands-on seek for astro telescopes. It has a reliable acceptance among astronomers. The Widescreen Centre,off Baker highway,is spectacular. you do not ought to purchase something in a hurry. merely pass and look and communicate approximately varieties of telescopes,mild toxins filters,(friendly marvel,eh?)Telescope abode (until eventually now Broadhurst Clarkson and Fuller) are out of Holborn now,moved to Kent,yet their internet site is properly worth staring at,as is David Hinds in Tring,30 miles north of London.you may get an instant practice from Euston to Tring,and have a very relaxing trip there.I grew up on the area of there and pass to truly frequently.He has a extensive selection of astro kit and frequently has some 2d-hand kit(see the categorized's on his internet site) He ran his very own mirror-making employer for some years,so he knows what he speaking approximately. His mirrors are genuine classification.A small portable scope and a practice fee ticket will instruct you extra celestial gadgets than a great scope interior the midst of London,besides the shown fact that it isn't hopeless. merely locate the darkest internet site you could far off from the direct glare of streetlights. some wood artwork wonders for that,so if there's a park interior of sight,head for it.i've got seen incredibly distinctive nebulae from Burgess Park with a short-concentration 4-inch refractor,or perhaps 20x80 binoculars.have exciting.
Its down to Newton's Formula F G(mp * mo)/r^2 G Newton's gravitational constant mp mass of planet mo mass of object This determines the force of attraction for any objects with mass. We also know that F mo * g Which is the force due to gravity If we equate these equations we get mo * g G( mp * mo)/r^2 giving g G*mp/ r^2 The gravitational acceleration, g is calculated from the planets mass and radius For Earth g ~ 9.8 m/s^2 and on the Moon, g ~ 1.6 m/s^2 These values can be calculated from the above equation
Actually, its mass that really affects gravity. The equation for force due to gravity between two objects is G*m1*m2/r^2, where G is the universal gravitational constant, m1 and m2 are the masses of the objects, and r is the distance between their centers of mass. So, in fact, if Jupiter were the same mass as the Earth, you would actually feel LESS pull from gravity on Jupiter than on Earth. That's because when you stand on the surface, you are farther from the center. Hope that helps! UPDATE No math huh? Well, If you don't want to see the math and Delta V's example doesn't do it for you, then you're just going to have to accept the fact that more massive objects have a stronger gravitational field.
i've been in this situation before:/ i wouldn't make her that thing because she might get a little creeped out the best thing to do is to hint for example say i really like this girl but shes in a relationship and all girls are curious and want to know who there friends like anyway sooner or later she will say is it me? and you would just reply yes im sorry and if she says somthing like why are you sorry? then you know she likes you! Good look mine get back to e if it works out!
why is gravity not as intense on the moon as it is on earth, and why is it more intense on jupiter than the earth? Why does size effect gravity? It's been proven that what we call 'gravity' is actually a distortion of space itself caused by the presence of mass, like the mass of Earth, the moon, Jupiter, etc.,. A good analogy is to imagine a flat, thin sheet of rubber. If you place a golf ball on the rubber sheet a dimple (..distortion..) appears where the ball rests. If you remove the golf ball and replace it with a bowling ball the distortion will be much larger, with steeper sides. Just replace the rubber sheet with space and you should have a good understanding of how gravity works. The bottom line then is that the more MASS is present somewhere in space, the more intense will GRAVITY be on and around it. Earth has less mass than Jupiter, so Earth's gravity isn't as strong as Jupiter's.
