Answer:More On Uniform Circular Motion
Explanation:
because we do oky
We don't know anything about Shoreville, or the coastline or shoreline
around it. So the only answer we can offer is the broad world-wide average.
Between consecutive appearances of the moon at the same place in the sky,
there are two high and two low tides.
The moon appears to circle the entire sky in 29.531 days, whereas the
sky itself, referred to the sun, circles in 24 hours. So the moon takes
(29.531 / 24) = 1.2305 days
to return to the same place in the sky.
That period of time is also the cycle of the four tide extremes ... 2 highs
and 2 lows. So the period between two extremes averages
(1.2305 / 4) = 0.3076 day = 7.38 hours = 7h 23min .
If one extreme tide occurs at 12:00, we would expect the next one at 7:23 .
Answer:
Explanation:
In the decibel scale , intensity of sound changes logarithmically as follows
Value in decibel scale , the value of I₀ = 10⁻¹² W /m².
Putting the values
W/m²
Similarly for 54 dB sound intensity can be given as follows
I = 10⁻¹² x
W / m²
For intensity of sound the relation is as follows
I = 2π²υ²A²ρc where υ is frequency , A is amplitude , ρ is density of air and c is velocity of sound .
Putting the given values for 71 dB
= 2π² x 504²xA²x 1.21 x 346
A² = 60.03 x 10⁻¹⁶
A = 7.74 x 10⁻⁸ m
For 54 dB sound
= 2π² x 504²xA²x 1.21 x 346
A² = 1.1978 x 10⁻¹⁶
A = 1.1 x 10⁻⁸ m
Answer:
It exerts pressure everywhere inside the container.
Explanation:
Pressure is the forelce exerted by a body per crossectional area,ie pressure is force/area.In fluid system an important law that explains the behavior of fluid in a closed vessel is the Pascal law.It state that a liquid in a containing vessel exerts pressure undiminished in all direction in a vessel and to all portion of the fluid.
The answer is Computer game.
Scientific modelling is an experimental enterprise, the purpose of that is to make a distinct section or piece of the universe accessible to recognize, describe, quantify, imagine, or invent by connecting it to existing and customarily ordinarily allowed information.
