Energy Transformation for a Pendulum
Because there are no external forces doing work and the total mechanical energy of the pendulum bob is conserved. The conservation of mechanical energy is described in the animation below. Assume the KE and PE bars of the bar chart and their sum is a constant value.
A wheel is mounted on a stationary axle starts at rest and is given the following angular acceleration a =(9-12t) (SI units)where t is the time after the wheel begins to rotate.Fin
explain briefly voltaic cell
In the experiment, under which of the following circumstances is the angular momentum L of the movable puck NOT conserved? a) The net torque = 0. b) The radius r is always perpen
Q. Find the effectual resistance between A and B. 1/R p = 1/R 1 + 1/R 2 R p = R 1 R 2 / (R 1 + R 2 ) = 15 X15 / 30 = 7.5 ohm
two charge(q) each are kept 1m apart, where should third charge be placed in order to get third charge -q/4
Which one of the following pairs is not correctly matched: (1) Rutherford-Proton (2) J.J. Thomsom-Electron (3) J.H. Chadwick-Neutron (4) Bohr-Isotope Ans:(4)Bohr-Is
A) Explain the flow of direct current? ( describe direct current) b) Explain the effect of resistance in circuits? (Describe effect of resistance)
With the help of a circuit diagram, explain how regenerative feedback is provided in an Hartley oscillator?
if acceleration vs time graph is given then how to calculate displacement
(i) The size examines cannot be operated to derive relations other than product of power functions, for example, s = ut + 1/2 at 2 or y = y 0 cosωt and so on, cannot be derived
