Hey!
Given ,
Acceleration, a = 5 m/s^2
time , t = 10 seconds
Initial velocity,u = 0
Final velocity , v = ?
We have ,
v = u + at
=> v = (0)+(5)(10)
=> v = 50 m/s
The organism that could be considered as an example of a nekton is: Dolphin
Nekton is aquatic animals that have the capability to move independently within water currents.
Nektons are able to do this because they've developed their own unique mechanism to detect their own way within the currents (such as using biosonar or Antenne)
A). Kepler's first law of planetary motion ... "Each planet moves
in an elliptical orbit, with the Sun at one focus of the ellipse."
B). Heliocentric motion ... motion in an orbit around the Sun.
C). Eccentricity ... what makes an ellipse different from a circle.
The eccentricity of a circle is zero.
The eccentricity of the Earth's orbit is very small.
The eccentricity of a comet's orbit is big.
D). Retrograde motion ... the apparent, temporary, backward
motion of a planet on its path through the stars.
Answer:
<em>The internal energy change is 330.01 J</em>
Explanation:
Given
the initial volume = 5.75 L
the final volume = 1.23 L
is the external pressure = 1.00 atm
q the heat energy removed = -128 J (since is removed from the system)
expansion against a constant external pressure is an example of an irreversible pathway, here pressure in is greater than pressure out and can be obtained thus;
W = -ΔV
W = -1.00 x(1.23 - 5.75)
W = -1.00 x -4.52
W = 4.52 L atm
converting to joules we have
W = 4.52 L atm x 101.33 J/ L atm = 458.01 J
The internal energy change during compression can be calculated thus;
ΔU = q + W
ΔU = -128 J + 458.01 J
ΔU = 330.01 J
Therefore the internal energy change is 330.01 J
Answer:
% differ 1.72%
Explanation:
given data:
P_ideal = 13.51 atm
n = 1.074 mol
V = 1.746 L
T = 267.6 K
According to ideal gas law we have
(P+0.514)(1.711) = 23.59
P_v = 13.276 atm
% differ
= 1.72%
