Answer:
A sloping surface separating air masses that differ in temperature and moisture content is called a front.
Answer:
74dB
Explanation:
Sound intensity is inversely proportional to the square of the distance. Thus, a house four times closer hears a sound 16x more intense.
The dB scale is logarithmic, so 16x louder than 62 dB is equal to
62 + 10*log(16) ~= 62 + 12 = 74dB
You answer is b an oscillating wave
Answer:
C ) 33 s.
Explanation:
In simple harmonic motion damping of amplitude is logarithmic which is expressed as follows
A/A₀ = .3 (given ) , b is damping constant and t is time which is 30 s here.
ln .3 = -b / 30
1.2 = b / 30
b = 36 s 0r 33 s
