Answer:
Yes, the water level in the glass will decrease as the icecubes melt, this is a due to water displacement.
Answer: A surface wave is a wave that moves along the interface of two different materials, like air and water.
Answer:
D. Plane of orbital rotation
Explanation:
The orbital plane of an object orbiting around another is the geometric plane that contains the orbit in question.
By definition, the inclination of a planet in the solar system is the angle between the orbital plane of the solar system and the orbital plane of the Earth.
Answer:
The strength of the field
Explanation:
The density of field lines of a field (e.g. gravitational field, or electric field) indicates the strength or magnitude of the field itself. In particular:
- The regions in which the field lines are closer to each other (more dense) are the regions where the field is stronger
- The regions where the field lines are more spread apart (less dense) are the regions where the field is weaker
For example, if we consider the electric field generated by a positive point charge, the electric field is radial (outwards from the charge) and the spacing between the lines increases as we move away from the charge: this means that the strength of the field increases as we move away from the charge.
