MCAT Question of the Day


  • Q:

    A light source at a point P emits radiation in all directions evenly. Two objects sit a distance of r1 and r2 away from P where r2 > r1. The change in the amount of radiation received between r1 and r2 is directly proportional to:

     

    A

    (r2-r1)2

    B

    r2-r1

    C

    the change in surface area of spheres drawn with radii r1 and r2

    D

    the change in volume of spheres drawn with radii r1 and r2
