(a) Write down the definition of proper time and explain how to use the appropriate formula with an example.
(b) Write down the definition of proper length and explain how to use the appropriate formula with an example.
(c) At what relative speed does a clock move if it runs at a rate that...
so what's I've got so far is:
a) I've proved that the period increases when mass is increased because of F=ma, the heavier the mass the bigger the acceleration, when the mass increases, more force is then able to be compressed into the spring and therefore transferred back. Since there's no...
(a) The displacements of two traveling waves are given by:
D1(x,t) = A sin[kx +ωt +φ]
and
D2 (x,t) = A sin[kx −ωt +φ] where A=0.01m, k=5rad.m−1,ω=200rad.s−1 andφ=π3rad
(i) Use the appropriate trigonometric identity to find the displacement resulting from the superposition of these...
(a) A box of mass m, attached to a spring, oscillates in simple harmonic motion on a frictionless surface as indicated in the figure below. Each time the box reaches the point of maximum displacement a child allows some sand to fall vertically into the box. This will gradually increase the mass...
A turntable is rotating at a constant angular velocity of ω = 4.0 rad/s in the direction of a clockwise fashion. There is a ten-cent coin on the turntable, at a distance of 5 cm from the axis of rotation.
(a) Which one of the following options below correctly identifies the direction in which...
Polly the parrot wants to escape from her enclosure at the zoo. The enclosure has a glass door and by tapping on the door with her beak Polly has been able to determine that the natural resonant frequency of the door is 900 Hz. The highest frequency squawk Polly can muster is 850 Hz but at one...
