Answer:
the intensity of the sound waves produced by one 60-w speaker at a distance of 1.0 m is 60 w/m²
Explanation:
Intensity of sound , I, is given as;
I = P/A
Where;
P is the power through an area = 60-w
A is the area = ?
A = 1.0m × 1.0m = 1.0 m²
I = 60-w / 1.0 m²
I = 60 w/m²
Therefore, the intensity of the sound waves produced by one 60-w speaker at a distance of 1.0 m is 60 w/m²
Explanation:
36-4/4= 9 m/squared. meter per squared.
acceleration unit is meter per second Square.equation is velocity by time.for average final(36) minus initial(4)
Physical changes: breaking sticks, boiling the water
chemical changes: lighting the fire
(Breaking the wood does not change the substance of the wood , therefore it's a physical change. Water changing between solid, liquid, and gas form is always a physical change.)
