Answer:
Circle Q
Explanation:
The flux of a field through a surface is given by:
where
F is the field strength
A is the area of the surface
is the angle between the direction of the field and the normal to the surface
In the figure, we see that the 4 surfaces have different orientations, so different angle . In the formula, we see that the flux is maximum when
, which occurs when the field is perpendicular to the surface, and the flux is zero when
, (because
) which occurs when the field is parallel to the surface.
In the figure, we see that circle Q is parallel to the direction of the field, so in this case the field is zero, while in all the other cases is not.
So, the correct answer is
Circle Q
Answer:
3.75 m/s^2
Explanation:
The centripetal acceleration of an object in uniform circular motion is given by the equation:
where
v is the tangential speed of the object
r is the radius of the trajectory
In this problem, r = 60 m and v = 15 m/s, therefore the centripetal acceleration of the car is
