When you scan the hiker's body, you will notice a warm spot. Unless that person was dead, they would not be emitting heat.
<h3>What is hiking?</h3>
- According to Smokymountains.com, which examined more than 100 news reports of missing hikers, getting off the trail is the most common reason people get lost.
- That is not someone you want to be. Once you're on the trail, you can use the GPS to ensure you're on the right track.
- You can take it a step further by bringing a device like a Garmin IN Reach with you on the trail. This GPS also functions as a satellite communicator.
- Whereas hiking includes the word "walk," which is typically seen as jovial, easy, and pleasant, trekking is defined as a "journey," which is typically more difficult, requires more effort, and takes more than one day.

Answer:
Explanation:
a) Hardness is a measure of the resistance of a material to permanent deformation (plastic) on its surface,
Hardness tests play an important role in material testing, quality control and component acceptance.
Hardness test are needed to be perform as a <em>quality assurance procedure</em>, to validate materials are according to the specific hardness required,
We depend on the data to verify the quality of the components to determine if a material has the necessary properties for its intended use.
Through the years, the establishment of increasingly productive and effective means of testing, has given way to new cutting-edge methods that perform and interpret hardness tests more effectively than ever. The result is a greater capacity and dependence on "letting the instrument do the work", contributing to substantial increases in performance and consistency and continuing to make hardness tests very useful in industrial and R&D applications.
b)
- <u>Instrumental errors</u>: Instrument calibration is extremely important. An instrument with expired calibration may be generating erroneous data systematically.
- <u>Enviromental error: </u>An example is when surface preparation of the sample to be tested is poor, then the error can be presented when measuring the indentation on the sample to determine the hardness value.
-Velocity is the speed of any moving object in a given direction, whilst Speed is the rate of an object's ability to move.
-Velocity can change if the direction or time is changed, the basic equation of velocity is: v = d/t
v - velocity
d - distance
t - time
If one of these factors change, it affects the other.
Hope this answers the question!
- At pole the gravitation is more than that of equator .
And according to newtons second law
Force=Mass×Acceleration
And
- Hence force varies directly with acceleration hence weight will be more .
