YES I WILL HELP YOU SO MUCH
the neutron I hope i could help :)
Answer:
Explanation:
Given that,
Height of the inclined plane, h = 2.02 m
Final velocity of the object, v = 5.72 m/s
To find,
The moment of inertia of the object.
Solution,
As the object rolls down the inclined plane, its gravitational potential energy gets converted to the kinetic energy along with rotational kinetic energy.
Since,
On rearranging the above equation and finding the value of I as :
So, the moment of inertia of an object that rolls without slipping down is
Answer:
= 3.36 mm
Explanation:
From Ohm's law,
(Voltage = Current * Resistance)
The geometric definition of resistance is
where is the resistivity of the material, and are the length and cross-sectional area, respectively.
Since the wire is assumed to have a circular cross-section, its area is given by
where is the diameter.
Resistivity of copper = . With these and other given values,
Answer:
* angular momentum throughout the lar process is conserved throughout the entire process
* the angular velocity decreases as the radius of the pizza increases
Explanation:
The system formed by the masses is isolated so its angular momentum is conserved
initial instant, which throws the mass with angular velocity o and radius ro
L₀ = I w₀
final instant. When the mass has a radius r and an angular velocity w
L_f = I_f w
Lo = l_f
I₀ w₀ = I_f w_f
let's analyze this result
* angular momentum throughout the lar process is conserved throughout the entire process
* the angular velocity decreases as the radius of the pizza increases
