When it not to hot it just rite
Answer:
Explanation:
Atmospheric pressure = 7 x 10⁴ Pa
force on a disk-shaped region 2.00 m in radius at the surface of the ocean due to atmosphere = pressure x area
= 7 x 10⁴ x 3.14 x 2 x 2
= 87.92 x 10⁴ N
b )
weight, on this exoplanet, of a 10.0 m deep cylindrical column of methane with radius 2.00 m
Pressure x area
height x density x acceleration of gravity x π r²
= 10 x 415 x 6.2 x 3.14 x 2 x 2
=323168.8 N
c ) Pressure at a depth of 10 m
atmospheric pressure + pressure due to liquid column
= 7 x 10⁴ + 10 x 415 x 6.2 ( hρg)
= 7 x 10⁴ + 10 x 415 x 6.2
(7 + 2.57 )x 10⁴ Pa
9.57 x 10⁴ Pa
Answer: Peak wavelength
{lambda max}
= 9.7*EXP{-7}meter
Which is approximately,
1 micro-meter.
Explanation: lambda{max} which is peak wavelength is inversely proportional to temperature {T}.This is given by the wiens displacement law.
Lambda max
=max displacement{Xmax} / T
For the first case at T = 6000K
Lambda max = 483 nano-meter
=483*EXP{-9}meter.
So let's solve for max displacement {Xmax}.
Xmax = T*lambda max
= 6000*483*EXP{-9}
=2.898*EXP{-3}kelvin-meter
Xmax would be constant during Temperature change.
Therefore lambda max at 3000K would be,
Lambda max
= {2.898*EXP{-3} K-m} / 3000K
= 9.7*EXP{-7} meter
Which is approximately,
1*EXP{-6} meter= 1 micro-meter
NOTE: EXP used here means 10^.
Answer:
The speed of elevator fast and slows down shows through the diagram.
Explanation:
Given that,
Amanda has just entered an elevator. The elevator rises and stops at the third floor.
Let us consider the elevator at rest then the speed will be zero.
When elevator start from rest then the speed increases with constant acceleration and near the third floor it slow down with constant deceleration and finally becomes at rest at third floor.
We need to draw the diagram distance and time
Using given data,
First, the displacement A to B will be increases fastly and B to C the displacement increases slowly slowly.
Hence, The speed of elevator fast and slows down shows through the diagram.
