So the dimensions of acceleration is
Any answer that comes under that definition is correct.
Increasing the pressure of gas is like exactly the same as increasing its concentration. If you have a given mass of gas, the way you increase its pressure is to squeeze it into a smaller volume.
Hope this helps!
Answer:
a) w = 4.24 rad / s
, b) α = 8.99 rad / s²
Explanation:
a) For this exercise we use the conservation of kinetic energy,
Initial. Vertical bar
Emo = U = m g h
Final. Just before touching the floor
Emf = K = ½ I w2
As there is no friction the mechanical energy is conserved
Emo = emf
mgh = ½ m w²
The moment of inertial of a point mass is
I = m L²
m g h = ½ (m L²) w²
w = √ 2gh / L²
The initial height h when the bar is vertical is equal to the length of the bar
h = L
w = √ 2g / L
Let's calculate
w = RA (2 9.8 / 1.09)
w = 4.24 rad / s
b) Let's use Newton's equation for rotational motion
τ = I α
F L = (m L²) α
The force applied is the weight of the object, which is at a distance L from the point of gro
mg L = m L² α
α = g / L
α = 9.8 / 1.09
α = 8.99 rad / s²
Answer:
The acceleration of Abbie is half of the Zak's.
Explanation:
The centripetal acceleration of an object on a circular path is given by :
Two children are riding on a merry-go-round that is rotating with a constant angular speed. Let 
is distance of Abbie from the merry-go-round and 
is distance of Zak's from the merry-go-round. Acceleration of Abbie is :
...... (1)
Acceleration of Zak's is :
.......(2)
Dividing equation (1) and (2) we get :
So, the acceleration of Abbie is half of the Zak's.
Answer:
No
Explanation:
From the analogy of the problem we are made to know that "a man standing on the earth can exert the same force with his legs as when he is standing on the moon".
This force he is exerting is due to his weight. If he can have the same weight on the earth and moon, therefore:
weight = mass x acceleration due gravity
His mass and acceleration due to gravity on both terrestrial bodies are the same.
So, his jump height will be the same on earth and on the moon.
In summary, we have been shown that his mass and the acceleration due to gravity on both planets are the same, therefore, his weight will also be the same. His jump height will also be same.
