1. Illustrate how three forces [tex]2 \, N[/tex], [tex]3 \, N[/tex], and [tex]4 \, N[/tex] can be combined to give a resultant force of [tex]3 \, N[/tex].

2. State two properties of acids.


Sagot :

To illustrate how three forces, [tex]\(2 \, \text{N}\)[/tex], [tex]\(3 \, \text{N}\)[/tex], and [tex]\(4 \, \text{M}\)[/tex] can be combined to give a resultant force of [tex]\(3 \, \text{M}\)[/tex], we shall follow these steps:

### Step-by-Step Solution:

1. Identify the Magnitudes of the Forces:
- The first force, [tex]\( F_1 \)[/tex], is [tex]\( 2 \, \text{N} \)[/tex].
- The second force, [tex]\( F_2 \)[/tex], is [tex]\( 3 \, \text{N} \)[/tex].
- The third force, [tex]\( F_3 \)[/tex], is [tex]\( 4 \, \text{M} \)[/tex] (assuming [tex]\( \text{M} \)[/tex] represents Newtons).

2. Combine the Forces:
Forces can be combined using vector addition, which is commonly done either graphically or analytically by methods involving trigonometry or component analysis. Here we are given that the resultant force should be [tex]\( 3 \, \text{M} \)[/tex] Newtons.

3. State the Resultant Force, [tex]\( R_{\text{target}} \)[/tex]:
- The required resultant force, [tex]\( R_{\text{target}} \)[/tex] is [tex]\( 3 \, \text{M} \)[/tex].

Given the values:
[tex]\[ F_1 = 2 \, \text{N}, \quad F_2 = 3 \, \text{N}, \quad F_3 = 4 \, \text{M}, \quad R_{\text{target}} = 3 \, \text{M} \][/tex]

### Properties of Acids:

1. Acids Have a Sour Taste:
- One of the most common properties of acids is that they typically have a sour taste. For example, citric acid found in lemons gives them their sour flavor.

2. Acids Turn Blue Litmus Paper Red:
- Acids exhibit another characteristic property which is their ability to change blue litmus paper to red. This is a common qualitative test used to detect acidic substances in a laboratory setting.

Combining all the pieces of information, the illustration and the required properties are based on the given values and standard properties known of acids.
