Answer:
The object will accelerate in the upward direction.
Explanation:
To know the direction in which the object will accelerate, we shall determine the net force acting on the object. This can be obtained as follow:
Upward force (Fᵤ) = 300 N
Downward force (Fₔ) = 200 N
Net force (Fₙ) =?
Fₙ = Fᵤ – Fₔ
Fₙ = 300 – 200
Fₙ = 100 N upward
Thus, the net force acting on the object is 100 N in the upward direction. This implies that the object will accelerate in the upward direction because the net force acting on the object is in the upward direction.
The Q in the enthalpy of fusion equation stands for heat energy absorbed or released.
<h3>What is enthalpy?</h3>
In thermodynamics, enthalpy is a measure of the heat content of a chemical or physical system.
The enthalpy of fusion is the amount of heat energy required to convert a unit mass of a solid at its melting point into a liquid without an increase in temperature.
Its units are usually Joules per gram (J/g) or calories per gram (cal/g).
The enthalpy of fusion equation is given as follows:
Q = m·ΔHf
Where;
- Q = heat energy
- m = mass
- ΔHf = heat of fusion
Therefore, the Q in the enthalpy of fusion equation stands for heat energy absorbed or released.
