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...
Car on a Curve Problem: A car on a curve A car of mass m drives around a curve of radius R. The coefficients of static and kinetic friction with the ground are µs and µk, respectively. Q: Find an expression for the maximum speed with which the car can drive around the curve without sliding
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....

A car drives over a rounded hill. A) What is the fastest the car can go, in m/s, without the tires coming off of the road? B) If the mass of the car is 1500 kg, what is the net force on the car when it is at the top of the hill when it travels at a speed of 5 m/s?
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
10. Otis noticed that when he drives his car for 134 miles, the car's odometer records it as 135 miles. The odometer reading now is 121500 miles. What is the actual number of miles the car has been driven? 3
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...
Bob drives his car 119 km [N], then he stops to get gas. Then he drives his car 169 km [E], and stops to eat doughnuts. The he drives his car 279 km [S], and his journey ends. Bob's trip is completed in a time of 9.61 hours. The mass of his car is 1617 kg. What is the magnitude of Bob's average velocity in km/h and the direction?
A car drives over a hilltop that has a radius of curvature 0.114 km at the top of the hill. At what speed would the car be traveling when it tires just barely lose contact with the road when the car is at the top of the hill? (Give answer to the nearest 0.1 m/s)
