Product Information

c Sketch a graph to show how you would expect the mass’s acceleration to vary with time, starting with the mass in its position of maximum negative displacement. Identifying forces You can determine how an object will move by considering all the forces acting on it.

Sketch a graph to show how the Earth’s gravitational potential ϕ varies as an object is moved away from its surface. d Show the resultant displacement if the original and the wave in part c pass through the same point. Fundamental particles including quarks This exercise helps you to learn about some types of quark and where they are found in the nucleus, and which particles are leptons and which particles are hadrons. Calculating the momentum of an object is not difficult, but remember that momentum is a vector quantity. With more advanced maths, it can be shown that the upthrust on an object immersed in water is the same no matter how it is orientated.d Explain why a satellite dish on Earth in line-of-sight with a geostationary satellite is fixed in position. Think about what happens in destructive and constructive interference when waves have different amplitude. A student wants to obtain a large heating effect in a resistor connected to a laboratory power supply. a Complete these statements about progressive waves: In longitudinal waves the vibrations are _______________ to the direction of the energy transfer.

g Sketch a graph to show how the ship’s acceleration changes up to the time when it reaches terminal velocity. In fact, the pressure at the surface of the liquid is atmospheric pressure, due to the atmosphere above.N kg−1) b In the right-hand diagram, a positive charge of +20 C is being pushed from C to D through a potential difference of 2. The definition of gravitational field strength g says that its value is the force acting per unit mass acting near a body of mass m. This is an exercise in calculating and using gravitational field strength for different objects in the solar system. By comparing a specific equation to this ‘standard equation’, you can deduce a great deal of information about the motion of an oscillating mass.
