A particle executes linear some with an amplitude if 2 cm.when the particle is at 1cm from the mean position the magnitude of its velocity is equal to that of its acceleration.Then its time period is?Ans) velocity at distance x in shm is given as v= w sqrt(A2-x2)so A = 2 x =1v = w sqrt(4-1) = wsqrt3now acc at distance x is a= w2 x = w2as mag a = mag vw2 = wsqrt3w= sqrt32pi/T= sqrt3T = 2pi/sqrt3
A universe is spatially flat, and contains both matter and a cosmological constant. For what value of Om,0 is t0 exactly equal to H0 -1?
Does weight affect how far you jump? For the same leg strength / jumping method, weight affects how far one can jump. Acceleration = Force / Mass With more mass, you can
Q. An aircraft having awing span of 10 m flies at a speed of 720 kmph. If the vertical component of the earth's magnetic field is 3 X 10 -5 T, calculate the emf induced between th
