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)
Difference among sound and light waves: (i) For propagation of sound rays material phase is required but no material medium is needed for light waves. (ii)Sound rays are long
the center of oscillation of a meter stick suspended about a transverse axis is located at 10 cm mark. determine at what other positions the meter stick could be suspended and have
Q. Give the differences between hard X-rays and soft X-rays.
What do you understand by reverberation? Who is the founder of architectural acoustics? What is Newton's formula for velocity of sound in a gas? How is it corrected by Laplace?
Magnesium is the lightest of the structural metals. While this low density is an attractive property, magnesium also has a high corrosion rate that has often been seen as a disadv
A motor has an output of 4.8kW, an efficiency of 80% and a power factor of 0.625 lagging when operated from a 240V, 50Hz supply. It is needed to improve the power factor to 0.9
Give reasons for the following (i) Long distance radio broadcasts use short-wave bands. (ii) The small ozone layer on top of the stratosphere is crucial for human survival.
Why rotation of rigid bodies through finite angles not a vector? Ans) Because it does not obey one of the laws of vector algebra(law of commutativity).
Introduction and Definition: The force between two particles was studied by Coulomb in 1785. He stated that the force of attraction or repulsion between two charged particle
Q. Compute the resistance of the filament of a 100W, 220 V electric bulbs. Power P = V 2 /R Resistance R = V 2 /P = (220 X 220)/ 100 = 484 ohm.
