Answer:
Another metaphor that can help explain energy quantization at the atomic level is the number of teams at different stages in the Football World Cup tournament taking each stage as a given amount of energy gained by the teams at that stage as follows;
Stage 1 Group Stage
The number of teams in the group stage = 32, Energy per team = 1
Knock out stages
Round of 16
The number of teams in the round of 16 stage = 16, Energy per team = 2
Semi final
The number of teams in the semi final stage = 8, Energy per team = 4
Quarter final
The number of teams in the quarter final stage = 4, Energy per team = 8
Final
The number of teams in the semi final stage = 2, Energy per team = 16
The winning team
The number of teams that win the World Cup = 1, Energy of the team = 32
As seen as each team has a specific energy level at each stage of the world cup and there can not any energy value that is an intermediate value of the energy of the teams each at each stage, so also at the atomic level particles within the atom and therefore the atom itself can possess only specific quantum of energy values in a given level or state.

Answer:
0.19 rev
Explanation:
We can solve the problem by using the law of conservation of angular momentum. In fact, if we assume there are no external torques acting on the diver, the angular momentum must be conserved:
where
L is the angular momentum
I is the moment of inertia
is the angular velocity
- When the diver is tucked,
is her moment of inertia
She makes 2 revolutions (so, ) in t = 1.0 s, so her angular velocity is
So her angular momentum is
- When the diver is not tucked,
The angular momentum is conserved, so
the moment of inertia is
So the angular velocity is
So in a time of t = 1.5 s, the angular displacement is
Converting into revolutions,
Answer:
Size of image: 1.8 cm inverted
Magnification of camera: -0.1
Explanation:
Given:
- = size of bird = 18 cm
- = distance of the bird from the camera = 2 m = 200 cm
- = distance of the film from the camera = 20 cm
Assume:
- = magnification of the camera
- = size of image of the bird
Using sign convention, we have
The hole in the pinhole camera behaves as a convex lens. The other face opposite to the hole face behaves like a film where the image is formed to be seen. So, using the formula of magnification, we have
This means the image of the bird measures 1.8 cm in length where negative sign in the calculation represents that the image formed is inverted.
Hence, the image of the bird on the film is 1.8 cm large.
Now, again using the formula of magnification, we have
Hence, the magnification of the camera is -0.1.
<span>A mechanical wave is created when a source of energy causes a vibration to travel through a medium
And yeah lol
A mechanical wave is a disturbance in matter that carries energy from one place to another :)
This what you needed? </span>
