An oil drop of 12 excess electrons is held stationary under a constant electric field of 2.55x104 v/m. The density of oil is 1.26 gm/cc. Estimate the radius of the drop.[Ans:1.428x10-6m] 2. Two small spheres each of mass 10-6kg are suspended from a point by silk threads 50 cm long. They are equally charged and repel to a distance of 20cm.Calculate

equal force back. 4) State Newtons Second Law. Explain the second law using the rocket as your example. Newton’s second law states that force = mass x acceleration. This means they all link with each other‚ for example if somebody was to have all rockets with the same amount of air pressure‚ but a different mass it will affect the acceleration of the rocket. 5) State Newtons First Law. Explain the first law using the rockets as your examples. Newton’s first law state that an object at rest

ABOUT PHYSICS AND SOME MAIN TOPICS: 1. Temperature 2. Heat and thermal heat (energy) 3. Heat capacity 4. Phases of water 5. Expansion 6. Ideal gas 7. Laws of thermodynamics 8. Heat capacity of gas 9. Specific heat capacity TEMPERATURE is a physical quantity that is a measure of hotness and coldness on a numerical scale.[1] It is a measure of the thermal energy per particle of matter or radiation; it is measured by a thermometer‚ which may be calibrated

Physics is more around us than one would think. Physics is in all of the things you love to do. Take golf as an example there is velocity in a golf swing. Velocity is the speed of something in a given object and the speed of your club in the direction you are aiming is velocity. Also there is gravitational potential energy in the top of your backswing to cause you to pull the club downward. Kinetic energy is also in golf‚ During your backswing kinetic energy is causing your club to go up and in your

Smoke‚ which is composed of tiny particles‚ can rise thousands of feet into the air. Both these types of flight are possible because of the principles of physical science. Likewise‚ man-made aircraft rely on these principles to overcome the force of gravity and achieve flight. Lighter-than-air craft‚ such as the hot air balloon‚ work on a buoyancy principle. They float on air much like rafts float on water. The density of a raft is less than that of water‚ so it floats. Although the density of water

observation of nature with long-lasting implications for the study of physics. Correspondingly‚ Galileo constructed a telescope and supported the Copernican theory‚ which supports a sun-centered solar system. Also‚ Galileo was accused twice of heresy by the church for his beliefs‚ and wrote books on his ideas. He died in Arcetri‚ Italy on January 8‚ 1642 (Galileo Biography). In addition‚ the objective of the Incline Plane Experiment

Edgar Xiong David Blackburn Period 3 Physics of Flight One may wonder‚ what is flight? Many just stare up into the blue skies above and assume. while others devote their lives to discovering and finding a passion in aviation. Flight can be simply characterized as the [powered] gliding of an object through the air‚ but the wonders of soaring through the air does not simply stop there‚ instead‚ flight is a whole myriad of forces acting on each other‚ as so found out by scientists decades

PHY 305/601 Classical Mechanics Assignment No. 1 1. Consider a particle of mass m constrained to move on a frictionless cylinder of radius R‚ given by the equation ρ=R in cylindrical polar coordinates (ρ‚ φ‚ z). Besides the force of constraint‚ the only force on the mass is force F=-kr directed toward the originUsing z and φ as generalized coordinates find the Lagrangian L‚ solve Lagrange’s equations and describe the motion. 2. Show that the kinetic energy of any holonomic mechanical system has
