PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!! Which wave has the smallest amplitude?
1 answer:
Answer: Option (1) is the correct answer.
Explanation:
The vertical distance between crest or trough from the origin or equilibrium point is known as amplitude of a wave.
In the given pictures, a wave that shows maximum height from the origin will have the maximum amplitude. Whereas the wave that shows minimum height from the origin will have the smallest amplitude.
Thus, we can conclude that waves shown in option 1 will have the smallest amplitude.

Answer: v = 2.24 m/s
Explanation: The <u>Law</u> <u>of</u> <u>Conservation</u> <u>of</u> <u>Energy</u> states that total energy is constant in any process and, it cannot be created nor destroyed, only transformed.
So, in the toy launcher, the energy of the compressed spring, called <u>Elastic</u> <u>Potential</u> <u>Energy (PE)</u>, transforms into the movement of the plastic sphere, called <u>Kinetic</u> <u>Energy (KE)</u>. Since total energy must be constant:
where the terms with subscript i are related to the initial of the process and the terms with subscript f relates to the final process.
The equation is calculated as:
v = 2.24
The maximum speed the plastic sphere will be launched is 2.24 m/s.
