Answer: ok so u have to add the variable interia by the experiment bar to get ur total
Explanation:
surface wave of water is due to the disturbance of medium particles
this is also known as mechanical waves
In mechanical waves we need a mechanical medium to disturb the medium particles which will produce the disturbance
While electromagnetic waves do not require any medium and it can propagate through vacuum
Electromagnetic waves are propagation of electric and magnetic field which is due to oscillation of charge.
So electromagnetic field requires to and from motion of charge particle in which time dependent electric field will induce magnetic field and then they induce each other and propagate in the medium
Answer:
m₂ = 4 kg
Explanation:
The moment of inertia is defined by
I = ∫ r² dm
for bodies with high symmetry it is tabulated, for a spherical shell
I = 2/3 m r²
in this case the first sphere has a radius of r₁ = 2m and a mass of m₁ = 1 kg, the second sphere has a radius r₂ = 1m.
They ask what is the masses of the second spherical shell so that the moment of inertia of the two is the same.
I₁ = ⅔ m₁ r₁²
I₂ = ⅔ m₂ r₂²
They ask that the two moments have been equal
I₁ = I₂
⅔ m₁ r₁² = ⅔ m₂ r₂²
m₂ = (r₁ / r₂) ² m₁
let's calculate
m₂ = (2/1) ² 1
m₂ = 4 kg
