If the strength of the magnetic field is at field at A is 48 Units and the Strength of the Magnetic Field At B is 3 units, what is the Distance to B (Drawing is not a scale!) A. 400 Units
B. 25 Units
C. 80 Units
D. 20 Units

Awoman stands a distance d from a loud motor that emits sound uniformly in all directions. the sound intensity at her position is an uncomfortable 2.0×10-3 w/m2. at a distance 2.6 times as far from the motor, what are (a) the sound intensity and (b) the sound intensity level relative to the threshold of hearing?

Idon’t quite understand this problem

For this car, predict the shape of a graph that shows distance (x) versus time (t). note that time is the independent variable and will be on the bottom axis. need asap
