Consider the following three statements: 1. as children grow older, their weight increases. 2. as children grow older, they expand their vocabulary. 3. as children's weight increases, their vocabulary expands. does statement #3 describe a correlational relationship? a causal relationship? explain your answer.

This refers to two or more events that occur simultaneously but have no relationship between them.

The fact of expanding the vocabulary and increasing the weight of the child happens at the same time but does not relate to each other.

This is an example of a correlational relationship.

creative diagnostics provides a protocol for total protein extraction based on ripa which is widely used.

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
