which angle allows the soil to receive the most direct light from the lamp?\n0 degrees\n20 degrees\n45…

Brief Explanations:

Direct light means the light is perpendicular to the surface. When the angle between the direction of light - source and the normal of the surface is 0 degrees (i.e., the light is hitting the surface at a 90 - degree angle relative to the surface), the surface receives the most direct light.

Answer:

90 degrees
