Answer:
same as
Explanation:
According to Newton's 3rd law, the force that the Earth exert on the Sun would be equal (and in opposite direction) with the force that the Sun exerts on the Earth.
Also Newton's gravitational law states the formula for the attraction between objects with mass, is the same for both objects
Answer:
By the use of carbon nanotubes as the clothing material.
Explanation:
Carbon nanotubes is a technology designed by engineers that could make charging of the cell of a phone possible. It has some some required properties like it is strong, conductive and heat-resistant which are suitable for the purpose.
This technology which involves a progressive dipping of a pure cotton material into nafion polymer, then in a chemical solution of carbon nanotubes and finally in polystyrene until it becomes saturated and have a conductive property. The conductive cotton can be used to make such cloths which becomes conductive and produces some electromagnetic waves when there is a contact with sweat or fluid from the body. The waves generated can be used to charge a cell phone through radiation interaction.
The transfer of energy through matter by the direct contact of particles is called conduction
Explanation:
Speed has only magnitude.
Velocity has magnitude and direction.
"A bike goes 25 m/s toward main street."
This includes a direction, so it is velocity (V).
"A person walks 4 mph."
This has only magnitude, so it is speed (S).
"A plane flies 200 m/s."
This has only magnitude, so it is speed (S).
"A bird flies 100 mph due south."
This includes a direction, so it is velocity (V).
