Description

Draw diagrams to represent these electric fields: a the uniform field between two parallel plates with opposite charges b the field around a positively charged sphere c the field around a pair of charges, one positive and one negative.

A projectile travels the greatest horizontal distance on level ground if it is initially fired at 45° to the horizontal. Picture a collision in which a moving object collides with a stationary object; they stick together. a By taking moments about the right hand end of the pole, determine the value of the tension in the cable T. c Explain why the thermistor would be more useful for measuring temperatures close to 0 °C than to 100 °C. A single beam of red light from a laser shines on the double slit and a pattern of red dots is seen on the screen.c Suggest a point at which the charge could be placed so that the resultant electric force on it would be zero. b Use your definition of pressure to show that the pressure p at depth h in a liquid of density ρ is given by the expression p = ρgh, where g is the acceleration of free fall. Fully revised and updated content matching the Cambridge International Examinations 9702 syllabus for first examination in 2016. e By comparing the diagrams for a solid and a gas, you can see two ways in which the particles of a gas have more energy than the particles of a solid. Compare the phase difference between points at different distances along a stationary wave with the phase difference between points along a progressive wave.

Adding more masses to the hook hanging from the string increases the speed of the progressive wave along the string. g In practice, a typical particle will be moving around so that it bounces off all six faces of the cube, rather than just two, as shown in the right-hand part of the diagram above. State two advantages for each of: a FM transmissions when compared with AM transmissions b AM transmissions when compared with FM transmissions. d Draw a diagram of the bung and add arrows to show the directions of its velocity and its acceleration.e Mark on your diagram the letter A at all the places where the resultant wave always has a maximum amplitude. d Calculate the same quantity using the equation: change in gravitational potential energy = mgh Do you get the same answer as you did for part c? The joule is defined as the work done (or energy transferred) when a force of 1 N moves a distance of 1 m in the direction of the force. State the speed of a β+ -particle and the speed of a particle of γ-radiation, each of which has approximately the same energy as the β− -particle. d. is needed to produce a field strength of 500 V m−1 between two parallel metal plates separated by 1.

a State whether the volume of the gas will increase or decrease as the temperature increases at constant pressure. Look at the peak of one line in the diagram at t = 0 and see how far it has moved along horizontally by the time t = 0. a Complete these statements about progressive waves: In longitudinal waves the vibrations are _______________ to the direction of the energy transfer.You can calculate the final temperature of the water like this: The steel and the water will reach the same final temperature.
