As the velocity of the sound source approaches the speed of sound, the wave fronts ahead of the object begin to appear as:

a-separately distinguishable waves

b-a single wave front
c-cylindrical
d-a cone shape shockwave.
Term 1

and when the velocity of the sound source exceeds the speed of sound, the wave fronts form:

Term 2

a-separately distinguishable waves

b-a single wave front
c-cylindrical
d-a cone shape shockwave.

The coulomb's law explains which of the following? select all the force between two charged objects is inversely proportional to the charge on each object. the force between two charged objects is directly proportional to the charge on each object. the force between two charged objects is directly proportional to the distance separating them. the force between two charged objects is inversely proportional to the square of the distance separat coulomb's law is similar to newton's 2nd law. if the force between two objects is f and the charge on both objects is doubled, the new force between the would now be 2f. if the force between two objects is 2f and the distance separating them is doubled, the new force between the objects would now o the be zf.
