Answer:
Scalar Quantity
Explanation:
A scalar has only magnitude, while a vector quantity has magnitude and direction.
An example of a vector would be 5m/s West.
net force= the sum of all the forces acting on the object
the frictional force is opposite to the direction of motion of the object
If the object moves to the right (positive) then the friction force moves to the left (negative).
so the net force: 50 N - 5 N = 45 N (B)
Tennis ball will move with 1/3 th velocity of plastic ball
<h2>Word from the list best fits definition - Option C</h2>
Convection best fits the definition transfer of heat through flowing material. This is because the logic is that it is the heat transference due to the mass transportation of particles within liquids. Example gases and liquids that includes melted ore.
It undergoes by advection, diffusion or both. Convection happens when molecules which have very heat energy in a liquid or gas transit and hold the place of molecules which have less energy of heat. Heat energy is shifted from hot areas to cooler areas by the phenomena of convection. The thick cold liquid drops into the warm regions.
