Answer:
To select a cell range:
Sometimes you may want to select a larger group of cells, or a cell range.
Click and drag the mouse until all of the adjoining cells you want to select are highlighted. In our example, we'll select the cell range B5:C18.
Release the mouse to select the desired cell range. The cells will remain selected until you click another cell in the worksheet.

Cell content
Any information you enter into a spreadsheet will be stored in a cell. Each cell can contain different types of content, including text, formatting, formulas, and functions.
Text: Cells can contain text, such as letters, numbers, and dates.

Explanation:
An object can store energy as the result of its position. For example, the heavy ball of a demolition machine is storing energy when it is held at an elevated position. This stored energy of position is referred to as potential energy. Similarly, a drawn bow is able to store energy as the result of its position. When assuming its usual position (i.e., when not drawn), there is no energy stored in the bow. Yet when its position is altered from its usual equilibrium position, the bow is able to store energy by virtue of its position. This stored energy of position is referred to as potential energy. Potential energy is the stored energy of position possessed by an object.
