Answer:
1.29 moles
0.753 moles
0.745 moles
Explanation:
PV=nRT
n=PV/RT
n=(1)(34.2)/(0.0821)(323.7)
n=1.29
n=PV/RT
n=(1)(22.4)=(0.0821)(362.15)
n=0.753
n=PV/RT
n=(1)(16.7)/(0.0821)(273.15)
n=0.745
In the ideal gas equation, T is measured in Kelvin.
Answer:The direction the wave travels is parallel to the displacement of the medium.LW.
Electromagnetic waves are an example of this type of wave. TW
Sound waves are an example of this type of wave.LW
Ir the wave propagates in the x‑direction, the medium is also disturbed in the x‑direction. LW
If the wave propagates in the x‑direction, the medium is disturbed in the y‑ and/or z‑direction. TW
The direction the wave travels is perpendicular to the displacement of the medium.TW
Explanación:
the main difference of Transversal AND Longitudinal waves (TW AND LW) is that the disturbation direction in the media with respect to the travel direction is well different for both cases. For TW the perturbation oscilatiew perpendicular to propagation direction of the wave.
In constrant for LW the disturbation oscilates in the same direction as the wave is propagating.
<span>Supercooling
is lowering the temperature of liquid below its freezing point. This is also
known as the cooling of liquid. Supercooling can be minimized by cooling the
liquid and steering the liquid fast while it is freezing. Freezers in the
refrigerators shows the example activity of supercooling.</span>
Answer: The surface of the pad pushes the rocket up while gravity tries to pull it down. As the engines are ignited, the thrust from the rocket unbalances the forces, and the rocket travels upward. Later, when the rocket runs out of fuel, it slows down, stops at the highest point of its flight, then falls back to Earth.
Answer:
v = 14.35 m/s
Explanation:
As we know that crate is placed on rough bed
so here when pickup will take a turn around a circle then in that case the friction force on the crate will provide the necessary centripetal force on the crate
So here we have

here we have

now we know that

here we have

R = 35 m
g = 9.81 m/s/s
now plug in all values in above equation
