the Q factor of a sonometer wire is 2 x 10³ . on plucking it makes 240 vibrations per second. calculate the time in which amplitude decrease to half the initial value.
a car from rest and moves with constant acceleration.the ratio of distance covered by the car in nth second to that covered in n seconds is
MAXIMUM VELOCITY IN SHM IS Vm. FIND AVERAGE VELOCITY OF MOTION FROM ONE EXTREME TO ANOTHER....
The gravitational field in a region is given by :
E= 5 N/ kg i 12 N/ kg J
If the potential at the origin is taken to be zero,
then the ratio of the potential at the points (12m, 0) and (0, 5m) is ??
TWO BALLS OF MASSES M EACH ARE MOVING AT RIGHT ANGLE TO EACH OTHER WITH VELOCITIES 6m/s AND 8m/s RESPECTIVELY. IF COLLISION IS PERFECTLY INELASTIC THEN WHAT IS THE VELOCITY OF COMBINED MASS
A BODY OF MASS M FALLS FROM H HEIGHT ON GROUND. IF e IS COEFFICIENT OF RESTITUTION OF COLLISION BETWEEN BOY N GROUN THEN WHAT IS THE DISTANCE TRAVELLED BY BOY BEFORE IT COMES TO REST
a large number of identical point masses m are placed along x-axis , at x=0,1,2,3,4.....the magnitude of gravitational force on mass at origin (x=0), will be ??
If r0 = 20869 χ 10-10 m and E0 /KB= 10.22 K for He calculate and plot the Lennard Jones potential? Set one molecule at a fixed (pinned) position on the x-axis, say at x = 5 nm. The other molecule starts at the origin with initial velocity v0 =v0 (x cosβ +y sinβ) where β is small angle between v0 and the x-axis. Develop a computer program to calculate the trajectory of the moving particle in the x-y plane for various v0 and β , based on (a) the rigid-elastic-sphere assumption and (b) the intermolecular force field. Comment on the differences between the results obtained from the two models?
