The slope of the line on a velocityversus time graph is equal to the acceleration of the object. If the object is moving with an acceleration of +4 m/s/s (i.e., changing its velocity by 4 m/s per second), then the slope of the line will be +4 m/s/s.

Answer:
The enthalpy of fusion of a substance, also known as heat of fusion, is the change in its enthalpy resulting from providing energy, typically heat, to a specific quantity of the substance to change its state from a solid to a liquid, at constant pressure.
I think it's in the same column as a sodium on the periodic table because chemical properties are based on their electron structure and the columns called groups are elements with the same shell structure which increases in mass as you go down the column, therefore the elements which are similar to sodium must be in the same group.
The density in units of grams per milliliter is 1.0026 g/ml.
<h3>What is density?</h3>
Density is the measurement of how tightly a material is packed together.
Density = mass/volume (kg/m³)
Density = 2.09 lb/quart
1 pound = 0.454 kg = 454 g
1 quart = 946.353 ml
Conversion of the weight in lb/ml to grams per milliliter (g/ml)
= 2.09 lb/quart x 454 g/lb x (1 quart / 946.353 ml)
= 1.0026 g/ml
Thus, the density in units of grams per milliliter is 1.0026 g/ml.
