Abike is pushed with a net force of 2.5 n, and it accelerates 0.5 m/s2. if you pushed the bike with twice that amount of net force, the acceleration would be
0.25 m/s2 because net force and acceleration have an inverse relationship.
0.5 m/s2 because the net force and acceleration do not affect each other.
more than 0.5 m/s2, but less than 1 m/s2 because net force and acceleration do not have a proportional relationship.
1.0 m/s2 because net force and acceleration have a proportional relationship.

The illuminance of a surface varies inversely with the square of its distance from the light source. if the illuminance of a surface is 120 lumens per square meter when its distance from a certain light source is 6 meters, by how many meters should the distance of the surface from the source be increased to reduce its illuminance to 30 lumens per square meter?
