White colour is actually a mix of several different colours. Luckily, that is not the case. Congrats on the HOTD! The visibility of the moon during the daytime also depends on its angle and its distance from Earth. "Frequently asked questions about the rainbow. Renz Kristofer Cheng from Manila on September 13, 2012: This is a wonderful hub that is so much informative. Carrie Lee Night from Northeast United States on September 15, 2013: Fun and interesting hub ! JP Carlos from Quezon CIty, Phlippines on September 13, 2012: Well done on the HOTD. Parallax is the apparent displacement of an object because of a change in observer’s point of view, for instance, when we look at object with one eye shut and then doing the same with other eye, there is a difference in the position of the object this is known as Parallax. Matter tells space how to curve; curved space tells matter how to move. The ocean is blue for the same reason the sky is blue: the shortness of blue light waves. They a "thrust reverser" which changes the direction of the spinning blades in the thruster so that air is thrust forward instead of back. Just like tank tracks moving at different speeds, this causes the boomerang to turn in the air and return to the thrower. A day on the moon is equal to 29.5 Earth days. A helicopter, for example, appears to stand still in the air as its propeller pulls the aircraft up at the same rate gravity pulls it down. Enjoy! Airplanes abide by Newton's third law of physics to stay in the air. Dark matter is an invisible matter in the space that can hold the stars into the galaxy. The film's human protagonist, Dave, jumps out of a space pod to re-enter his spacecraft. Radioactivity involves the spontaneous decomposition of an unstable atomic nucleus into a more stable form, in one of three decays: alpha, beta, gamma. What is the irregular and instantaneous motion of air called? Physics explains the aurora, the movement of the planets, what are colours, what is temperature and so much more. Physics is seen as the most difficult of the sciences; my pupils usually greet a new physics module with a groan and "I can't do physics!" Physics is far from boring! Ups and bonuses! Given the choices though, I voted for Physics. (Young children should ask an adult to help.) You can test this by comparing water with another liquid such as cooking oil, which doesn't evaporate so freely. Still have questions? great explantions, the wet water questions is answered greatly.. What is a kind of digestion where food is broken down by chemicals produced by the body. removes tool for defrauded students, Synagogue fined for massive maskless wedding, Amazon just launched its massive Black Friday deals, Chrissy Teigen gives first interview since pregnancy loss, Publix worker's family blames policy for COVID-19 death. What is the magnitude and angle to the horizontal of the baseball's velocity when it was first thrown? Science is all about asking questions, and some of the most interesting and thought-provoking questions come from the imaginations of children. I got answers for all my questions that come to my mind. Blue light travels in short, choppy waves whereas red light travels in long, smooth waves. If the bird sat on a wire and touched the metal of the pylon or another wire, it would also complete a circuit and get electrocuted. The understanding of behaviour of matter and energy at the molecular, nuclear, atomic and even microscopic levels is referred as Quantum physics. Can you give the correct answers about each of these physics questions. if astronauts are returned into a pressurized oxygen environment within 90 seconds. This is because there are many more water molecules in the ocean; even though their individual kinetic energies are lower than those in a kettle, when taken together the overall energy is much higher. This means that whenever the moon reflects the sun's rays we can see it–even in the day time. An entire planet would have to be completely surrounded by the trampoline (in a sphere of directions) as are all of the other bodies with mass in the universe. The friction force is 190 N. What is the mass? Rachel Koski Nielsen from Pennsylvania, now farming in Minnesota on September 14, 2012: Great hub! by ... Rate 5 stars Rate 4 stars Rate 3 stars Rate 2 stars Rate 1 star . Below is a table listing the different colours the sky the cause of its changed colour. A boomerang has two airfoils, each facing in a different direction. This results in the colours fanning out. Once thought to be an impossible speed, Chuck Yeager broke the sound barrier with the Bell X-1 rocket plant in 1947. Once the star position is located after six month they will again calculate the apparent change in position. Stars, and other objects of great mass, are like bowling balls sitting on the trampoline. Weirdly, however, gravity is pathetically weak! To prevent outside interference, the router uses a precise frequency band - just like a walkie-talkie. of water. And, of course, when the sun is out, birds sunbathe to keep warm. Dip one index finger in each liquid, lift them out, and then observe for a few minutes.". This is good reading material for kids who are home for the summer. There are one or two things you need to think about if you found yourself in this situation: NASA has limited experience of this phenomenon, but experience from training accidents suggests that injuries can be reversed. Smoke from forest fires or agricultural burns can cause the sky to appear this colour. This is one thing that we physicist know but another thing is that we need to discover what our unerverse holds so keep up the good work guys. With more fat, they are able to generate more heat when they need it. If a bird was touching the ground while touching the wire, the ground would act as a neutral wire and the current would flow through the bird, electrocuting it. 11) Explain what is Wave-Particle duality? Another way of looking at it, according to the United Kingdom's Science and Technology Facilities Council, is in its equivalent to Indian elephants. Report: Secret Service agents asked to relocate with Trump, Repairman who found Hunter Biden data closes shop, 'DWTS' crowns new champion and viewers are not happy, Burt's Bees apologizes for offensive holiday ad, David Maas, NBA halftime showman, dies of COVID-19, Summers 'skeptical' about student loan forgiveness, Education Dept. The router decodes the signals and fetches the relevant data from the internet through the wired Ethernet connection. They have no effect of electromagnetic force on it, which means it does absorb, reflect or emit light that makes them practically invisible. If the entire human population stepped on a scale, the weight would be 316 million tons (or 632 billion pounds), according to a study by the London School of Hygiene and Tropical Medicine. Quiz Flashcard. What is another name for a volt-ohm meter? Join Yahoo Answers and get 100 points today. Can u please give complete details of work of maglev train. When you try to browse the internet using your laptop, an adaptor within the machine communicates with the router via radio signals. Voted physics. Dyne is a unit of force or also referred as C-G-S (centimetre – gram –-second). Can I ask a question about a physical issue? Gravity has undergone some modifications since Newton, with Einstein's General Relativity providing an explanation of how gravity worked. For instance, Light can behave like wave when it shines through narrow slits while, when exposed to some metal surface it will spray electrons acting as a particle. complete your postgraduate degree in physics then apply UGC-CSIR NET when u qualified jrf then do p.hd with fellowship then u become a Professor. Blue light waves travel in short, choppy waves. This push is stronger than gravity, and so makes the plane fly. WOW! But, hey! Fabulous Hub! For this to happen, there must be rain, mist, or moisture in the air, and the moon must be reflecting the sun's light very brightly. Required fields are marked *. Properties of Plasma are. It varies directly as the square root of elasticity and inversely as the square root of the density. 12) Explain what is Quantum tunnelling? The colours of the daytime sky and the causes of its varying colour. Jennifer Essary from Idaho on February 02, 2012: Great Hub with excellent explanations! If you were in an airplane and saw a rainbow below you, it would appear as a full circle. The reason for this is pollution. Fast Fact: Felix Baumgartner is planning a skydive from 36,500m - he will fall so fast he will become the first person to break the sound barrier without mechanical help. Every one of these questions are ones that children ask and many don't have the answer to. The Earth has a surface area of 197 million square miles.
