Answer #1

Since antenna is given it is vertical, the maximum emf will occur when car is traveling perpendicular to the horizontal component of the Earth magnetic field.This occurs when the car is traveling in the east or west direction

Emf = Blv cos (45°)

Given B = 5*10^-4 , l= 64.2 cm ,v = 40.3m/s

= 5*10^-4*0.642 * 40.3 * cos45°

= 91.47*10^-4 V (or ) 9.147 mV

Part A ) emf = 9.147 mV

Part B) option B) car direction should be in east or west

    Can I please get the solution for this problem. 2. A car drives over a piece of bubblegum, which sticks to the back right tire. The car is initially moving at 55 m/s. The driver then accelerates at a constant rate for 5 s. The final translational speed of the car is 60 m/s. If the driver began his acceleration at t 0 s, determine the full equation of motion for the bubblegum
