Some humans judge temperature without the use of instruments include:
- touching the object
- feeling the radiant energy
<h3>What is temperature?</h3>
Temperature is the measure of the degree of hotness or coldness of a substance.
Temperature of substances are usually measured using thermometers.
The choice of thermometer depends on the temperature range to be measured.
However, some crude ways of measuring temperature include:
- touching the object
- feeling the radiant energy
In conclusion, temperature measures the hotness or coldness of objects.

Answer:
<em>The rubber band will be stretched 0.02 m.</em>
<em>The work done in stretching is 0.11 J.</em>
Explanation:
Force 1 = 44 N
extension of rubber band = 0.080 m
Force 2 = 11 N
extension = ?
According to Hooke's Law, force applied is proportional to the extension provided elastic limit is not extended.
F = ke
where k = constant of elasticity
e = extension of the material
F = force applied.
For the first case,
44 = 0.080K
K = 44/0.080 = 550 N/m
For the second situation involving the same rubber band
Force = 11 N
e = 550 N/m
11 = 550e
extension e = 11/550 = <em>0.02 m</em>
<em>The work done to stretch the rubber band this far is equal to the potential energy stored within the rubber due to the stretch</em>. This is in line with energy conservation.
potential energy stored = 
==> 
= <em>0.11 J</em>

At what angle height and range of projectile are equal?
It means that the range of the projectile with a given initial velocity is same for a pair of projection angles θ and 90° – θ.
Jasmine need to correct the error by switching the headings on the columns adding the title parallel circuits.
<h3>What is a parallel circuit?</h3>
A parallel circuit is a circuit in which the components are connected to a common junction. This implies that if one bulb goes out in a parallel connection, all the bulbs will go out.
As such, Jasmine need to correct the error by switching the headings on the columns adding the title parallel circuits.
