Using the kinetic energy 1/2mv^2 formula
5*10^5 is the answer
Answer:
The volume of the ideal gas on another planet will be 6.7 m³.
Explanation:
We can find the volume occupied by the ideal gas on another planet by using the Ideal Gas Law:
Where:
P: is the pressure
V: is the volume
n: is the number of moles
R: is the gas constant = 8.206x10⁻⁵ m³ atm K⁻¹mol⁻¹
T: is the temperature
Since the gas occupies a volume of 8.7 m³ with a pressure of 6 atm and temperature 4.8 °C on earth, we have the following number of moles:
Now we can calculate the volume occupied by the ideal gas on another planet:
With T = 8.7 °C and P = 7.9 atm
Therefore, the volume of the ideal gas on another planet will be 6.7 m³.

As they evolved and adapted, those of the fittest survived to reproduce. Those that did not adapt, died.
The work done is 46 J
Explanation:
The work done by a force pushing a body is given by
where
F is the magnitude of the force
d is the displacement of the body
is the angle between the directions of the force and of the body
In this problem:
F = 23 N
d = 2 m
(we assume the force is parallel to the displacement)
Therefore, the work done is
