Answer:
Explanation:
The system boy-skateboard can be modelled by means of the Principle of Momentum Conservation:
The final velocity of the skateboard:
Explanation:
In this case, it is required to match the following terms with their definitions.
1. Amplitude : the maximum displacement of particles (positive or negative) during wave motion.
2. Crest : the high point of a wave.
3. Frequency : The number of oscillations that occur in a given time period.
4. Hertz : the unit for the frequency of a wave; the number of waves per second.
5. Period : the time required for one wavelength to pass.
6. Stiffness : degree to which a medium resists being compressed.
7. Trough : the low point of a wave.
The above parameters are the characteristics of a wave. A wave is defined by the above parameters. Hence, this is the required solution.
Explanation:The input force is the force that is applied by the user of the lever. The output force is the force applied by the lever to an object.
