Answer:
The pressure is 
Explanation:
From the question we are told that
The initial pressure is 
The temperature is 
Let the first volume be 
Then the final volume will be 
Generally for a diatomic gas
Here r is the radius of the molecules which is mathematically represented as
Where 
are the molar specific heat of a gas at constant pressure and the molar specific heat of a gas at constant volume with values
=> 
=> 
=> ![P_2 = [\frac{1}{2} ]^{\frac{7}{5} } * 11.2](https://tex.z-dn.net/?f=P_2%20%20%3D%20%20%5B%5Cfrac%7B1%7D%7B2%7D%20%5D%5E%7B%5Cfrac%7B7%7D%7B5%7D%20%7D%20%2A%2011.2)

Answer:
a = 1.1 m/s^2
Explanation:
let a be the acceleration of the astronaut, M be the mass of the earth and r be the radius of the earth.
from the information provide:
the distance r is the radius of the earth.
the distance ,d, the astronaut is from the surface of the earth and the only force acting on the astronaut is gravity, the astronaut accelerates with due to gravity only that is d = 3×r because we consider the earth center as the center of mass and gravity attracts object towards the center of mass.
then, we know that:
a = GM/d^2
= (6.67×10^-11)(5.972×10^24)/[(3×6371×10^3)^2]
= 1.1 m/s^2
Therefore, the Astronaut will be accelerating with an acceleration of 1.1 m/s^2 towards the earth.
Answer:
k = 1,250 N/m
Explanation:
Use the formula F=kx, with F=5N and x=0.04m
Then the spring constant (k) is 5/0.04
