Answer:
Explanation:
From the exercise we have:
To find the velocity after 2.4s we need to use the following formula:
The negative sign means that the kit is going down.
Answer: 6.65 rad/s
Explanation:
Firstly, we need to know that according the kinetic theory of gases, the average kinetic energy of a molecule with degrees of freedom is:
(1)
Where:
because oxigen is a diatomic molecule and has 5 degrees of freedom
is the Boltzman constant
is the temperature
Then:
(2)
(3) With this value of average kinetic energy we can find the average angular velocity, with the following equation:
(4)
Where:
is the moment of inertia
is the angular velocity
Now, (5)
Being the molar mass of Oxigen molecule and the distance between atoms
(6)
(7)
Substituting (7) and (3) in (4):
(8)
Finding :
(9) This is the average angular velocity for a molecule of O2
Answer:
First answer to the first question is Two people pulling a rope with the same force in a opposite direction. The other one would be 2.72N

Hope this helps you :)
Explanation:
they would formulate a new hypothesis with the same dependent variable but a different independent variable as a virginal hypothesis .
The answer is : Low frequency sounds
place theory is a theory of hearing which states that our perception of sound depends on where each component frequency produces vibrations along basilar membrane, which is very sensitive to low frequency sound
