What does component mean? what does humus mean? what does qualitative data mean? what does quantitive data meanwhat does hypothesis meanand what does justify mean

A component to something means a part or piece.

Humus is the organic compound in soil/earth

Qualitative data is specific data you record about something that has to do with the physical features of that item. Say you look at a pencil. That pencil is yellow. It is not sharpened. Something like that

Quantitative data is data that has to do with numbers. A hexagon has 6 sides. There are 3 birds in that tree. That pen has two different colors.

A hypothesis is an educated guess about something

Justify means to explain/prove a point that you are making. If you say something like ice melts faster in hot water vs cold water, you would justify it by testing ice in hot and cold water, and recording the results.

I hope this helps :)

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy
