We will determine the magnitude of the final component as follows:

So, the magnitude is approximately 8.36.
And the direction will be approximately 57.8° counter-clockwise.
This can be seeing as follows:
A situation that involves the transfer of heat by means of convection must involve the exchange of fluid currents such as land and sea breezes.
Heat transfer by convection is a method of heat transfer by which heat is transferred between two bodies through through currents of moving fluids or gases.
The following are examples of heat transfer by convection;
- land breezes cooling the sea at night
- sea breezes cooling the land during the day
- boiling of water
- circulation of blood, etc
Thus, a situation that involves the transfer of heat by means of convection must involve the exchange of fluid currents such as land and sea breezes.

Answer:
Velocity
Explanation:
Kinetic Energy of a body can be defined as the amount work needed to accelerate a body of mass, m, from a position of rest to a particular velocity.
It is also the energy possessed by a body due to its motion.
Mathematically, it is given as:

As seen from the formula, the Kinetic energy is dependent on the mass of the body, m, and the square of the velocity, v.
Typically, the mass of an object is a constant value, hence, the kinetic energy varies as velocity varies.
