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

When a car drives through the Earth's magnetic field, an emf is induced in its vertical 60-cm-long radio antenna. Part A If the Earth's field (5.0x10-5 T) polnts north with a dip angle of 38°, which direction(s) will the car be moving to produce the maximum emf Induced in the antenna? Check all that apply. in the west direction in the east direction the south direction in the north direction Submit Previous Answers Correct Part B What is the maximum...

Zero Launch Angle - Car Drives Off a Cliff A car drives straight off the edge of a cliff that is h =40 m high. The police at the scene of the accident note that the point of impact is d =86 m from the base of the cliff. Here the initial speed v0 is unknown. Ignore air resistance. The magnitude of the gravitational acceleration is 9.8 m/s2. Choose the RIGHT as positive x-direction. Choose UPWARD as positive y-direction. A....

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

3. A car drives along a bumpy road on which the bumps are equally spaced. At a speed of 20 mph, the frequency of hitting bumps is equal to the natural frequency of the car bouncing Amplitude on its springs. a) Draw a graph of the car's vertical bouncing amplitude as a function of its speed if the car has new shock absorbers (large damping coefficient). b) Draw a graph of the car's vertical bouncing amplitude as a function of...
