Figure shows an arrangement of a carriage system. A force P is applied on the carriage B and moving rightward at 3 m/s2 constant acceleration. At the instant shown the velocity of B is 2 m/s.
(i) Determine the velocity of B relative to A.
(ii) Determine the acceleration of B relative to A
(iii) Determine the absolute velocity of C, Carriage A
(iv) Determine the absolute acceleration of carriage A
(v) Determine the force P and the tension in the rope if mass A= 50 kg and mass B=40 kg (neglect the masses of pulleys, rope and the friction forces at the wheels)
What is magnetic moment of a bar magnet 1. When a bar magnet of pole strength (m) and length (2l) is suspended freely in air,it always turns along the magnetic north (N) and S
Q. Give the drawbacks of Sommerfeld’s atom model? Drawbacks of Sommerfeld's atom model: (i) It couldn't explain the distribution and arrangement of electrons in atoms.
(1) The first practical application for piezoelectric devices was sonar, first developed during worldwar1. Piezoelectric materials are as a source of ultrasonic waves. At sea, they
Boltzmann constant; k (L. Boltzmann) This is a constant that describes the relationship among temperature & kinetic energy for molecules in an ideal gas. This is equal to 1.380
