Answer:
The approximate combined sound intensity is
Explanation:
The decibel scale intensity for busy traffic is 80 dB. so intensity will be
, therefore
In the same way for the loud conversation having a decibel intensity of 70 dB.
, therefore
Finally we add both of them , is the approximate combined sound intensity.
Explanation:
As we know that
time = distance/speed
The time used for firs half of the trip was
(1 mi)(12 mi/hour) = 1/12 hours = 5 minutes
The last half of the trip will took 10 minutes, 1/6 hour.
Speed = distance/ time
(1 mil) = (1/6h) = 6 mil/h
so the speed for last half of the trip was = 6mph
the average speed was
(2mil)(1/4 hour) = 8 mil/hour
So the ling's average speed was 8mph.
Answer:
The mass of the asteroids is 0.000334896182184 times the mass of the Earth.
39929.4542466 m
Explanation:
Total mass of the asteroids
= Mass of Earth =
The ratio is
The mass of the asteroids is 0.000334896182184 times the mass of the Earth.
Volume is given by
The diameter is 39929.4542466 m
They can be compounds too.
Examples: salt, sugar, and water are all compounds, not elements or mixtures.
