Application of surface tension:
1) A needle placed on water can be made to float due to the surface tension of water.
2) Mosquito eggs can float on water because of its surface tension.
3) Toothpaste contains soap, which reduce the surface tension and helps it spread freely in the mouth.
Answer:
Relative Dating
Explanation:
Relative dating is used to determine a fossils approximate age by comparing it to similar rocks and fossils of known ages. Absolute dating is used to determine a precise age of a fossil by using radiometric dating to measure the decay of isotopes, either within the fossil or more often the rocks associated with it.
Answer:
The correct option is;
c. Temperature and color
Explanation:
Based on Wien's Law which can be presented mathematically as follows;
The wavelength of the peak of the blackbody curve tells the temperature and color.
An example is the Sun that has a temperature of 5800 K, hence the peak wavelength is given by 
= 500 nano-meter from which the color can be deduced as 500 nano-meter is the wavelength of yellow light.
