Answer:
Pnitrogen=3.18 kPa, Poxygen=1.62 kPa , Ptotal= 4.80 kPa
Explanation:
partial pressure equation becomes Ptotal = Pnitrogen + Poxygen
Partial pressure of Nitrogen
Pnitrogen= nRT/V
n=no of moles =mass/molar mass
mass of nitrogen=0.6kg
Molar mass of nitrogen gas=28gmol^-1
n=0.6/28=0.0214moles
R=0.2968 kPa·m3/kg·K
T=300k
V=0.6m^3
Pnitrogen=(0.0214 * 0.2968 * 300)/0.6
Pnitrogen=3.18 kPa
Likewise
Poxygen=nRT/V
n=0.4/32=0.0125moles
R=0.2598 kPa·m3/kg·K
T=300k
V=0.6m^3
Poxygen=(0.0125 * 0.2598 * 300)/0.6
Poxygen=1.62 kPa
Ptotal= 3.18+1.62= 4.80 kPa
Answer:
Time=15,Mass=3,Acceleration due to gravity=10,Height=50,Power=?.
Power=mgh/t.....which is 3×10×50=1500/15=100Watts.
Answer: 39.08664m
Normal free fall:
2s = 19.6133m/s
1s = 9.08665m/s
Assuming there's no air resistance:
The first second of the fall it will travel 15m
since the initial speed of the ball is 15m/s
this leaves us with 1 second, however by the time the ball ha traveled 1 second it will be accelerated by the force of gravity (9.08665)
15 + 9.08665 = 24.08665
We're already travelled 15m
and now 24.08665 will be covered in
the last second.
24.08665 + 15 = 39.08664m
-/
if we're gonna be technical:
a coins terminal velocity is only roughly around 19km/s so it wouldn't even travel much
(a brainliest would be appreciated)
<h3><u>Answer;</u></h3>
C. Waves transfer energy, but not matter.
<h3><u>Explanation;</u></h3>
- <em><u>A wave is a transmission of a disturbance from one point to another. Wave involves transmission of energy from one point to another through a materials medium.</u></em>
- <em><u>Waves may require or may nor require a material medium for transmission. </u></em>Those wave that do not require material medium for transmission are electromagnetic waves while those that require material medium are called mechanical waves.
- <em><u>Mechanical waves</u></em> transfers energy through the vibration of particles of the medium through which the wave travels, while<em><u> electromagnetic waves t</u></em>ransfer energy through the vibration of electric or magnetic fields.
- <em><u>Waves transfers energy from one point to another without moving matter.</u></em>
