The "unstretched length" is shorter than the actual unloaded length because the load applied to the material caused the extension of the material thereby increasing its length.
<h3>Hooke's law</h3>
Hooke's law states that the force applied to an elastic material is directly proportional to the extension of the elastic material.
F = kx
where;
- F is the applied force
- k is the spring constant
- x is the extension
Thus, we can conclude that, the "unstretched length" is shorter than the actual unloaded length because the load applied to the material caused extension of the material thereby increasing the length of the material.

Answer:
The answer is letter B, absorb.
Explanation:
Heat travels through three different ways: radiation,conduction and convection.
Radiation- this happens when heat moves as energy waves (infrared waves) directly from its source to something.
Conduction- heat passes directly from one object to another through the touching of surfaces.
Convection- this occurs when warmer areas of a liquid or gas rise to cooler areas in the liquid or gas.
The transfer of heat in the situation above is an example of "thermal radiation." The campfire carries light energy through the fire. These consists of electromagnetic waves (most of these are infrared light). These waves (radiation) carry energy, which is then converted to heat once it hits another object that absorbs it. In the case above, once the hands absorbs the energy, it then warms up. This happened because the hands are placed <u><em>near the campfire.</em></u> Placing the hands near the campfire is important because air is a poor thermal conductor.
Thus, the answer above is letter B, absorb.

Answer:
Isaac walked a distance of 5 blocks, and his displacement was 3 blocks north.
Explanation:
Distance is what he covered from the beginning, while displacement was what he covered in a specific direction
Explanation:
Tables and graphs are visual representations. They are used to organise information to show patterns and relationships. A graph shows this information by representing it as a shape. Researchers and scientists often use tables and graphs to report findings from their research.
