The law of inertia is the second name for Newton's first law of motion, which states that B) a body in motion will continue in motion unless acted upon by an outside force.
The reason that space crafts do not need to be propelled is because there is no frictional force slowing them down as there would be on earth. This means that the craft keeps moving, according to the law of inertia.
Answer:
Energy or calorific flow.
Explanation:
Energy flow, which is also called the calorific flow, is defined as the flow of energy through an ecosystems food chain. It is the focus of study in ecological energetics and also how energy is converted from one form to another in an ecosystem.
Example of a typical energy flow: Solar energy is fixed by the photoautotrophs, called primary producers, like green plants which uses the energy for photosynthesis.
they are the lithosphere (land), hydrosphere (water), biosphere (living things), and atmosphere (air).
Okay thank goodness for the reason why I am not trying it out lol I love
Answer:

Explanation:
<em>Longitudinal</em><em> </em><em>waves</em><em> </em>are parallel to the direction of the motion of the disturbance, while <em>transverse</em><em> </em><em>waves</em><em> </em>are perpendicular to the direction of the motion of the disturbance.
