Answer:
B. 0 degrees
Explanation:
The magnetic flux through a certain area enclosed by a loop of wire immersed in a region with magnetic field is given by:
where
B is the strength of the magnetic field
A is the area enclosed by the coil
is the angle between the direction of the magnetic field and the direction of the normal to the coil
From the equation above, we see that the magnetic flux is maximum when
So when the field is parallel to the normal to the coil (so, when it is perpendicular to the coil), therefore when:
So, the correct option is
B. 0 degrees
Answer:
Explanation:
Acceleration can be found by dividing the change in velocity by the time.
where Vf is the final velocity, Vi is the initial velocity, and t is the time.
Since the car came to a complete stop, it's final velocity was 0 meters per second.
The initial velocity was 22 meters per second.
The time was 2.0 seconds.
Substitute the values into the formula.
Subtract in the numerator first.
- 0 m/s- 22 m/s = -22 m/s
Divide.
The acceleration of the car was -11 meters per square second. The negative acceleration indicates slowing down/stopping.
