Answer 1

Answer #1

h = 22.6cm = 0.226m , v = 5.7cm/s = 0.057m/s , B = 2.88T

And t = 2.07s

Change in flux = B∆A = Bhv∆t = 2.88×0.226×0.057×2.07

=) Change in flux = 0.0768wb = 0.077Wb

Chapter D3, Problem 03/149 The 222-kg lunar lander is descending onto the moon's surface with a velocity of 4.3 m/s when its retro-engine is fired. If the engine produces a thrust T for 5.8 s which varies with the time as shown and then cuts off, calculate the velocity of the lander when t - 6.7 s assuming that it has not yet landed. Gravitational acceleration at the moon's surface is 1.62 m/s? The velocity is positive if moving downward,...
