This line lies 100km above sea level and is named after aeronautical scientist Theodore von Kármán. Birds can also fluff up their feathers to make air pockets that keep them even warmer. Because the bird's only sits on one wire, it is safe. 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. The lift is generated because the air flowing up over the curve of the wing has further to travel than the air flowing past the flat side. How to solve General Knowledge Physics problems? You may view your performance graphically via the colored Score bar and numerically.

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. Hint: Treat the groove as a thin ring of material. Pity that i do not have children of that age and grandsons are just passing that inquisitive stage. We are glad to help you, if you will pick the answer you believe is right and tell us why, our experts will be glad to help you. What do you expect to see if the center of mass of the container is offset from the geometric center O of the container? How do I register and join my instructor's course? Please take care as far as possible to post your questions and doubts without any error in grammar etc. An airfoil is flat on one side but curved on the other with one edge thicker than the other - this subjects the boomerang to lift, keeping it in the air.

You can test this by comparing water with another liquid such as cooking oil, which doesn't evaporate so freely. If one junction of the couple is kept hot and the other is kept cold then, an electric current will flow from Antimony to Bismuth at the cold junction flow from Antimony to Bismuth at the hot junction flow from Bismuth to Antimony at the cold junction not flow through the thermocouple 11. They usually only happen when it is still raining. Where can I get General Knowledge Physics questions and answers with explanation? Q: In a tug of war, when one team is pulling with a force of 100 N and the other 80 N, what is the net force? When you try to browse the internet using your laptop, an adaptor within the machine communicates with the router via radio signals. The printed book reinforces the material you encounter in the PreLecture lessons online and provides a subset of the related homework problems.

But what makes a metal magnetic? In the quantum world, particles are not billiard balls, but rather buzzing, jumping clouds of probability that aren't in one place at one time, and don't travel from point A to point B along a single path. An airplane, too, can appear to stand still if there is a strong headwind coming towards it that keeps it in place. Problem 5 What is the difference between centripetal acceleration and centrifugal force? Increase acceleration, decrease acceleration 10. The film's human protagonist, Dave, jumps out of a space pod to re-enter his spacecraft. Material that permit electrons to flow freely from atom to atom and molecule to molecule b. You are right about mathematics.

Find the maximum cable tension during the lift, which includes the part of the lift before the pump casing loses contact with the ground, and after the pump casing loses contact with the ground lift off. Some birds even feather flock together, which is when they pack together in a tight huddle and share body heat. The questions along with answers will be published on this site. The Earth has a surface area of 197 million square miles. Process of heat transfer from one location to the next by the movement of fluids c.

The rate at which an object changes its velocity 8. The PreLectures have been carefully designed to deliver a coherent presentation of key concepts using the minimum amount of time possible. You can easily solve all kind of General Knowledge questions based on Physics by practicing the objective type exercises given below, also get shortcut methods to solve General Knowledge Physics problems. The belt is inclined at an angle θ. You didn't read that very well now did you? Can You See a Full Moon During the Day? Gravity is pulling equally on all the particles in your body. Decrease acceleration, increase acceleration d.

Solution For Problem 6 Power is the rate of energy being generated or consumed. Solution For Problem 3 Without loss of generality, we only need to look at the equation for the x-position, since we know that centripetal acceleration points towards the center of the circle. A wireless network in not truly wireless as it is built around a source computer connected to the internet via an Ethernet cable. Problem 6 What is the difference between energy and power? Q: What is the push or pull on an object that can cause it to accelerate called? Problem 9 An archer pulls back 0. That's because we've become used to it, and our bodies, having lived under the weight of the sky since infancy, have developed the necessary muscles to carry that weight. To keep the belt in tension a weight of mass m is suspended from the belt, as shown.

Weirdly, however, gravity is pathetically weak! Let both liquids come to room temperature for a day, or overnight. Bright green represents the points that have been awarded, the white region represents points you can still earn but you have to complete the activity , and the red bar represents points that can no longer be earned e. Physics Questions On this page I put together a collection of physics questions to help you understand physics better. Many people believe Wi-Fi is short for 'Wireless Fidelity' what does that even mean? The questions embedded within the PreLectures provide feedback to you about your understanding of a given concept before letting you move onto the next slide. The electical current that comes out of your plug sockets is the former.

With all that weight, it's surprising we don't notice it as it presses on us evenly from all directions. The rod connecting the pivot to the wheel makes a constant angle θ with the vertical. Fast Fact: While the temperature of the Southern Ocean stands between -2°C and 10°C, it contains much more heat energy than a boiling kettle. You can switch sections or classes using the same access code within 30 days of activating your code.

The dipole will experience a torque only a translational force only in the direction of the field a translational force only in a direction normal to the direction of the field a torque as well as a translational force 14. With more fat, they are able to generate more heat when they need it. I am taking two smartPhysics classes this term. If it is due to evaporation give with full proof and with the facts that should be clear to all of us. The laptop then decodes this message and hopefully shows you the page you googled! This hub looks at questions asked of me in a year of teaching physics - the questions have come from young and old alike, so there should be something of interest for you here. In this stage the pump casing swings back and forth.
