An automobile has a vertical antenna 1.40 m long. The automobile travels eastward at 65 km/h on a horizontal road where the Earth's magnetic field is 50.2

Expert Solution

Giventhat the length of the antena is L = 1.40 m

the velocityof the auto mobile is v = 65.0 Km/h =65.0 Km/hr (1m /10^-3Km)(1hr/ 3600s)

= 18.06 m/s

the earths magnetic field is B = 50.2?T =50.2*10^-6 T

---------------------------------------------------------------------------------

if the top of the antenna positive relativeto the bottom , for aximum antenna

F = q(v ? B)

so the auto must movetowards east because angle is 90degrees

? =B*L*v

= ( 50.2*10^-6 T )*(1.40 m )(18.06 m/s)sin 65.5⁰

= 1.155*10^-3 V

An automobile is traveling on a long, straight highway at a steady 75.0 m/h when the driver sees a wreck 170 m ahead. At that instant, she applies the brakes (ignore reaction time). Between her and the wreck are two different surfaces. First there is 140 m of ice, where the deceleration is only 1.20 m/s^2 . From then on, it is dry concrete, where the deceleration is a more normal 7.90 m/s^2 . What was the car’s speed just...

A speeding motorist zooms through a 50 km/h zone at 75 km/h (21 m/s) without noticing a stationary police car. The police officer immediatley heads after the speeder, accelerating at 2.5m/s^2. When the officer catches up to the speeder, how far down the raod are they, and how fast is the police car going? I know you use the equations x= x_0+ v_0t+ .5at^2 and v= V_0 + at... But I want to know why we use these equations and...
