An unbalanced force is required to accelerate an object according to Newton's Second Law of Motion.
<h3>What does Newton's Second Law of Motion state?</h3>
It states that the force applied to the object is equal to the product of mass and acceleration.
- An object will accelerate when the net force applied on the object is more than zero or unbalanced.
- The acceleration is the change in the direction or speed of the object. To achieve acceleration the force must be greater in a direction.
- When force is greater in one the object move in that direction which is known as acceleration.
Therefore, an unbalanced force is required to accelerate an object according to Newton's Second Law of Motion.

Answer:
The final equilibrium temperature of the system is
For the ice it would melt completely the mass that would remain is Zero
Explanation:
In the following question we are provided with
Mass of the ice = 129 g = 0.129 kg
Mass of the steam = 19 g = 0.019 kg
Initial temperature is = 0°C
Temperature of steam = 100°C
Following the change of state of water in the question
The energy required by ice to change to water is mathematically given as
Where is a constant known as heat of fusion and the value is
The energy been released when the steam changes to water is mathematically given as
Where is a constant known as heat of vaporization and the value is
The energy released when the temperature of water decrease from 100°C to 0°C is
100°C)
Where is the specific heat of water which has a value
Looking at the values we obtained we noticed that ]
What this means is that the ice will melt
bearing in mind the conservation of energy
looking the way at which water at different temperature were mixed according to the question
Heat lossed by the vapor = heat gained by ice
