Answer:
Coulomb's law states that the electrical force between two charged objects is directly proportional to the product of the quantity of charge on the objects and inversely proportional to the square of the separation distance between the two objects.
Explanation:
At stp conditions (

), the speed of sound is

The sound wave moves by uniform motion, so we can use the basic relationship between space, time and velocity:

where S is the distance covered by the sound wave in a time t. In our problem, t=3.00 s, therefore the distance covered by the sound wave is
The momentum of an object is given by:
p = mv
m is the object's mass and v is its velocity.
Given values:
m = 15kg
v = 25m/s
Plug in the values and solve for p:
p = 15*25
p = 375kg×m/s
The answer of this is C!!!
