Answer:
Option B: the period during which a solid is not changing state; its temperature is increasing
Explanation:
The temperature is defined as a measurement of the speed at which particles of matter are moving (their kinetic energy)
Therefore for an increase of kinetic energy to take place, and increase of temperature has to occur.
We have that the <em>statements</em> found falsifiable is
Henry Ford invented the first automobile.
Option A
<h3>Henry Ford</h3><h3 />
Generally in as much Ford motor is a great vehicle company
He did not create the first automobile
Credit is give to Karl Benz for The first auto-mobile
Therefore
The statements found falsifiable is
Henry Ford invented the first automobile.
Option A

The displacement of the train after 2.23 seconds is 25.4 m.
<h3>Resultant velocity of the train</h3>
The resultant velocity of the train is calculated as follows;
R² = vi² + vf² - 2vivf cos(θ)
where;
- θ is the angle between the velocity = (90 - 51) + 37 = 76⁰
R² = 8.81² + 9.66² - 2(8.81 x 9.66) cos(76)
R² = 129.75
R = √129.75
R = 11.39 m/s
<h3>Displacement of the train</h3>
The displacement of the train is the change in position of the train after a given period of time.
The displacement is calculated as follows;
Δx = vt
Δx = 11.39 m/s x 2.23 s
Δx = 25.4 m
Thus, the displacement of the train after 2.23 seconds is 25.4 m.
