I believe the answer is "radioactive decay".
Answer:
air pressure in the air-tight bag is greater than cabin air pressure
Explanation:
Explanation:
Let's look at the forces on the two axes:
Substituting (2) into (1) and solving for , we get
Answer:
x = 0.327 m
Explanation:
Block 2 of mass 1.00 kg is at rest
spring constant = 200 N/m
Block 1 of mass 2 kg moving at 4 m/s
m₁ v₁ = (m₁ + m₂)V
2 x 4 = (2 + 1) V
V = 2.67 m/s
loss of kinetic energy = gain elastic potential energy
x = 0.327 m
hence, the spring compressed distance is equal to x = 0.327 m
The wave speed completely depends on the characteristics and properties of the medium . . . physical properties for mechanical waves, electrical properties for electromagnedtic waves.
So if you want to change the speed of a wave, you have to change the medium . . . shoot it through some different kind of stuff. <em>(B) </em>
