The chemical formula for the compound strontium sulphide would be SrS.
According to the question, the determined melting point of the compound is 112.5-113.0oC. When the solidified compound was retried, the melting point was found to be 133.6-154.5oC. This greater range higher than 112°C is caused by reusing samples leads to errors.
A pure sample is known by its sharp melting point. A pure sample does not melt over a large range. We can see this in the predetermined melting points of the pure sample(112.5-113.0oC).
However, reusing a sample introduces errors because the pure sample may become contaminated leading to a larger and higher range of melting point (133.6-154.5oC) which is far above 112°C.

Since f=ma assuming you knew the mass of the marble and the total amount of force acting on it than you would divide the amount of force by the mass.
Kinetic energy is is the energy of mass in motion basically the kinetic energy of an object is the energy it has because of its motion an example of kinetic energy would be, well let’s say you have a ball and you let that ball fall the potential energy then converts into kinetic energy or the energy associated with the motion and there are five types of kinetic energy like (radiant and thermal and sound and electrical and mechanical! Hopefully this help!
