A substance could have physical characteristics and chemical ones too, which are unique to the certain substance.
Color, odor, and how hard the substance, are all examples of physical characteristics of a substance.
Toxicity, flammability, and acidity, are all examples of chemical characteristics of a substance.
Answer:
C. reflects one or more visible light frequencies.
Explanation:
The color that we see is the color that is deflected from the RGBHSB.etc. This means that the light has all the colors within, and the object it hits absorbs all but one color, in which it deflects for our eyes to see.

The stretching force acting on the second wire, given the data is 588 N
<h3>Data obtained from the question</h3>
- Radius of fist wire (r₁) = 3.9×10⁻³ m
- Force of first wire (F₁) = 450 N
- Radius of second wire (r₂) = 5.1×10⁻³ m
- Force of second wire (F₂) =?
<h3>How to determine the force of the second wire</h3>
F₁ / r₁ = F₂ / r₂
450 / 3.9×10⁻³ = F₂ / 5.1×10⁻³
cross multiply
3.9×10⁻³ × F₂ = 450 × 5.1×10⁻³
Divide both side by 3.9×10⁻³
F₂ = (450 × 5.1×10⁻³) / 3.9×10⁻³
F₂ = 588 N

Answer:
- collecting information
- imaging
Explanation:
Remote sensing means we do not have to be physically present in that particular area that we're studying by taking certain measurements. Several tools have been developed overtime to enable us to make this feat possible. Satellites in orbit have a major role to play in this regard. They exist to gather information from outer space and captures images that help us know more about our universe.
Hope that answers the question, have a great day!
