the reason why sound travels faster in solid is because the molecules in solid is more close to each other and they allow the waves of the sound to travel quickly or easily. and same reason why the sound travels fast in liquid that gas, it's because the molecules in liquid is closer to each other than the molecules in gas but they're not as close as solid hence why solid is the fastest at traveling sound
To solve this problem we will use the general system of simple harmonic movement and compare this structure with the given value. From this equation we can find the phase. Our given value is
Data:
t = 2 s
The expression given from the theory for the harmonic movement is:
Where,
= Phase Angle
A = Amplitude
Here the Phase angle is given as
Comparing we have,
Replacing the time of t, we have that
Therefore the phase of motion at t=2s is
Answer:
Fluorine is the 9th element of the periodic table. If its Neutral... It'll have an atomic mass of 19. Also Since its neutral... Number of protons and Electrons will be the same which is 9. Now the Neutron number is the Mass number - The atomic no = 19-9 = 10Neutrons
Answer:
2.61 atm
Ley de Boyle
Explanation:
= Presión inicial = 0.96 atm
= Presión final
= Volumen inicial = 95 mL
= Volumen final = 35 mL
En este problema usaremos la ley de Boyle.
La presión ejercida sobre el émbolo para reducir su volumen es de 2.61 atm.
