Please read site and peruse the page before submitting your question. Problem 3 An object is traveling in a straight line. This creates a sensation where no forces are acting on you and you feel weightless.
Problem 6 When a vehicle makes a turn, the two front wheels trace out two arcs as shown in the figure below. There is now an Ask the Physicist page. Problem 11 A heavy pump casing with a mass m is to be lifted off the ground using a crane. Difficulties often arise when students get overly involved in memorizing specific details and physics questions without understanding the main principles of how to apply specific information to the problem. The crane pulls up vertically on the cable with a constant velocity V p. You get 1024 characters of space to ask a question.
It would be the same sensation as if you were floating in space. Physics Help Online Sometimes it is inevitable that you need quick. Solution For Problem 9 This can be solved using an energy method. The center of mass G of the pump casing is assumed to lie in the center of the rectangle. You get only customized online support with any topic that you are facing difficulties with.
Other times, not so much. If you want to send the question via email to the masters, use the form below. You need to spend only a few minutes in order to register and place an order. If you'd like to ask us a , not already covered, please read our first. Here you can find objective type General Knowledge Physics questions and answers for interview and entrance examination. We correspond to individual lists of requirements and are always ready to meet new challenges. You may ignore gravity in the calculations.
If you have a doubt in Physics or a question troubling you, just post it here. In the parabolic mirror you can see the reflection of the landscape. They have passed months of training before they have started to work with our service. Focus your physics studying on solving problems during the time spent in lectures, by reading the texts, or reviewing for exams. Please stop sending me obvious textbook problems. 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. Took a girl friend's daughter to an area in north Texas to collect specimens for a class assignment about butterflies and moths.
Assume there is no friction between merry-go-round and ball. Specify the answer in terms of θ. For example, you can ask a question on Twitter and may get a response be sure to use the chemistry hashtag for more visibility. To ask right now — simply enter the information below. Problem 4 How come in free fall you feel weightless even though gravity is pulling down on you? The arrow can be treated as a particle since it is not rotating upon release. Don't forget to try other forms of social media.
Also, by preventing the wheels from locking up you have greater control of the vehicle. The linkages of identical color have the same length. Radiocarbon is produced in the atmosphere as a result of collision between fast neutrons and nitrogen nuclei present in the atmosphere action of ultraviolet light from the sun on atmospheric oxygen action of solar radiations particularly cosmic rays on carbon dioxide present in the atmosphere lightning discharge in atmosphere 2. During half a rotation the flywheel has to absorb 1000 J of energy. You can search for what you need or use the form to email your question. The net dynamic force acting on the fluid is the net force required to accelerate the fluid, which occurs when the velocity of the fluid increases as it flows from the larger diameter section to the smaller diameter section due to conservation of mass. During the engine cycle the spring is compressed between 0.
Hi, I'm Liz Swann Miller. Static friction exists if the wheels keep rolling on the ice without locking up, resulting in maximum braking force. Usually you can at least get a good idea of how to approach a problem. Since 1999 I have answered more than 6000 questions on line and many more by brief email. Solution For Problem 2 If an object were completely immersed in a liquid denser than it, the resulting buoyant force would exceed the weight of the object. Our system directs all unanswered queries to experts who deal them on instant basis as they come in the queue.
