Answer:
Sound intensity is the amount of energy carried by sound versus loudness is a subjective measurement of the audible sound.
Sound intensity is measured in watt per square meter where loudness is measured in sones (sone is a subjective measurement and not an SI unit)
A and C is the correct one
Use the kinematics equation:
d = vt + 1/2at^2.
In this problem,
v = 15 m/s.
a = 3 m/s^2,
t = 10 s,
So:
d = 15(10) + 1/2*(3)*(10^2) = 300 meters
Reflection- looking at yourself in a mirror and seeing the moon in the sky
Refraction- putting on your glasses in order to see more clearly and the pencil looks like it’s bent when you stick one end of it in water.
