To have a force of 3.8x10-8 the two chaarges must be 0.65m apart.
When a constant force acts on an object, what does the object's change in momentum depend upon? check all that apply. check all that apply. the change in momentum depends upon the change in the velocity of the object. the change in momentum depends upon the mass of the object. the change in momentum depends upon the change in the position of the object. the change in momentum depends upon the time interval during which the force acts. the change in momentum depends upon the magnitude of the force?
Answer: Uniform Velocity-A body is said to have uniform velocity if it covers equal distance in equal intervals of time in a particular direction, however, the time intervals may be small. ... Examples of the body moving with variable velocity: 1.

Answer:
electrical power is converted by the speaker into sound power 17.25 %
Explanation:
given data
radius = 0.1158 m
power needed = 27.0 W
average sound intensity = 25.6 W/m²
solution
we know sound intensity that is
I = 
...................1
power = intensity × area
Power = 25.6 × 4 ×π×r²
Power = 25.6 × 4 ×π×0.1158²
power = 4.313 W
so here electric power % into sound power
= 
× 100
= 17.25 %
