Hey! So referring to the data the thing we can clearly see is that in a vacuum, everything, regardless of its mass, falls at the same speed.
Acceleration is often confused with speed, or velocity, but the difference is, acceleration by definition is the rate of which an object falls with respect to its mass and time.
Every single thing in the world falls at the same acceleration, this is because of gravity. The difference is the speed of which it falls. In space, there is not any gravity, and so, the objects are able to fall at the same speed regardless of their mass.
True because friction happens when two things are rubbed against each other and it creates force and sliding something vigorously against something else can create force.
Given, mass of titanium metal = 144 g
Heat of fusion of titanium metal= 18.7 J/g
Heat of fusion is the amount of heat energy needed to change the state of one gram of a substance from solid to liquid or vice-versa.
Thus, 18.7 J of heat is needed to melt one gram of titanium metal.
Therefore, heat needed to melt 144 g of titanium metal = 18.7×144
= 2692.8 J
