Answer:
Resonance depends on objects, this may happen for example when you play guitar in a given room, you may find that for some notes the walls or some object vibrate more than for others. This is because those notes are near the frequency of resonance of the walls.
So waves involved are waves that can move or affect objects (in this case the pressure waves of the sound, and the waves that are moving the wall).
this means that the waves are mechanic waves.
Now, in electromagnetics, you also can find resonance frequencies for electromagnetic waves trapped in things called cavities, but this is a different topic.
Answer:
Explanation:
Total time of transfer oil fuel = 2.45 x 9 = 22.05 minutes
= 22.05 x 60
= 1323 s
Total volume of ful transferred = 687 gallon
= .0037854 x 687
= 2.6 m³
radius of pipe = .5 x 1.45 inch
= .5 x 1.45 x 2.54 x 10⁻² m
r = .018415 m
cross sectional area
= π r²
a = 3.14 x .018415²
= 10.648 x 10⁻⁴ m²
If v be the velocity
volume of fuel coming out a x v x t , a is cross sectional area , v is velocity and t is time .
10.648 x 10⁻⁴ x v x 1323 = 2.6
v = 1.845 m / s
Answer:
1.Temperature is a condition that affects the speed of sound. Heat, like sound, is a form of kinetic energy. Molecules at higher temperatures have more energy, thus they can vibrate faster. Since the molecules vibrate faster, sound waves can travel more quickly. 2.In physics, sound is a vibration that propagates as an acoustic wave, through a transmission medium such as a gas, liquid or solid. In human physiology and psychology, sound is the reception of such waves and their perception by the brain. 3. The speed of sound is faster in solid materials and slower in liquids or gases. The velocity of a sound wave is affected by two properties of matter: the elastic properties and density.
Answer:
110 mL
Explanation:
Ideal gas law:
PV = nRT
Assuming the container isn't rigid, and the pressure is constant, then:
V/T = V/T
Plug in values (remember to use absolute temperature).
V / 293 K = 150 mL / 393 K
V = 110 mL
