Answer:
w = w₀ / 2 the angular velocity is half the initial value.
Explanation:
We can analyze this exercise as if we added another disk to obtain a disk with twice the mass, for which if the system is two disks, the angular tidal wave is conserved
initial instant.
L₀ = I₀ w₀
final moment
L_f = I w
the moment is preserved
L₀ = L_f
I₀ w₀ = I w
the moment of inertia of a disk is
I = ½ m R²
we substitute
½ m R² w₀ = ½ (2m) R² w
w = w₀ / 2
for the case of a disk with twice the mass, the angular velocity is half the initial value.
Ways carbon is added to the atmosphere is through the respiration of animals, the decay of plant matter, combustion of organic materials, and volcanic eruptions.
150x2=300 90x2=180
the plane is travelling at 180mph
Answer:
tA=tB
tB=(sA-dA)/vA watch it below
Explanation:
the spatio for A is sA=vA*tA+dA
the spatio for B is sB=vB*tB
the meeting point will happen at: tA=tB
so, sA=vA*tB+dA
tB=sB/vB
yields:
sA=vA*(sB/vB)+dA
sA-dA=vA*(sB/vB)
sB=(sA-dA)*vB/vA
then
tB=((sA-dA)*vB/vA)/vB
tB=(sA-dA)/vA
Answer:
Wave A has a greater intensity and transfers more energy. Wave B has a greater intensity and transfers more energy.
