Answer:
A. The pressure denoted as Pa and Pb at the surfaces of A and B in the tube is
PA= Pgas
PB= Patmos
B. The second sketch
C. The gas pressure is
Pgas= Patmos+ rho.g(h2-h1)
= 1atm + rho.g (h2-h1)
Explanation:
Answer:
A. The wavelength doubles but the wave speed is unchanged
Explanation:
The relationship between the period and wavelength is direct. Doubling the period of the oscillator will correspondingly double the wavelength but the wave speed is unaffected
I am not sure if this is the answer you are looking for but a earthquake occurs when the plates shift.
Hope this helped.
Answer:
<em>20 m/s in the same direction of the bus.</em>
Explanation:
<u>Relative Motion
</u>
Objects movement is always related to some reference. If you are moving at a constant speed, all the objects moving with you seem to be at rest from your reference, but they are moving at the same speed as you by an external observer.
If we are riding on a bus at 10 m/s and throw a ball which we see moving at 10 m/s in our same direction, then an external observer (called Ophelia) will see the ball moving at our speed plus the relative speed with respect to us, that is, at 20 m/s in the same direction of the bus.
Answer:
hi there!
the correct answer to this question is: 6.67 mph
Explanation:
you convert minutes to hours
10 miles * 60 mins / 90 mins
