<span>Weight measured as a force in Newtonsis best described by the answer that is listed under option C. It is a measure of gravitational force on an object. So, interestingly an item with a specific mass of say 120KGs on earth would weigh 1200 N but on the moon only weigh 200 N due to the smaller gravitational force.</span>
A. hex- Normally with 6, the prefix is hex-. For example a polygon having 6 sides is known as hexagon.
Answer:
C. Speed
Explanation:
Density differences in different materials are able to change the speed of a wave.
- Wave speed is dependent on the frequency and wavelength of a wave.
- As a wave travels from one medium to another, the speed of the wave changes.
- Speed of a wave is medium dependent.
- The denser a medium, the slower the speed of waves will be be.
- A less dense medium will have waves traveling through faster.
