Answer: When you speak into the can, your voice creates air vibrations that travel into the can, vibrate the bottom of the can, which in turn vibrates the string all the way over to the other can, in turn vibrating the other can's bottom, then the air again.
Explanation:
Answer:
0.62 rad/s
Explanation:
Angular momentum is conserved.
I₁ ω₁ = I₂ ω₂
where I is moment of inertia and ω is angular velocity.
The total moment of inertia is the sum of the platform's inertia and the boy's.
(I + m r₁²) ω₁ = (I + m r₂²) ω₂
Given I = 1000 kg m², m = 50 kg, r₁ = 4.0 m, r₂ = 3.0 m, and ω₁ = 0.5 rad/s:
(1000 + 50 (4.0)²) (0.5) = (1000 + 50 (3.0)²) ω₂
900 = 1450 ω₂
ω₂ = 0.62 rad/s

Answer: 
Explanation:
We know Haley is driving with an initial velocity of 
and then she has to change to a velocity of 
in a distance 
, and we also know we are dealing with constant acceleration 
.
Therefore, the following equation will be useful:
(1)
Clearing :
(2)
(3)
(4)
Knowing 
and 
:
this is the constant acceleration that will bring Haley to lower speed
