Answer:
B. The foam has tiny air pockets that slow the transfer of thermal
energy away from the water in the pipe
Explanation:
Air is a poor conductor thermal energy and can be used as good insulator. Insulators are poor conductors of heat.
When it is freezing outside, the temperature gradient will tend to adjust to the ambient one. The water in the pipe being at a higher temperature will tend to lose heat energy to the surrounding.
The layer of foam will prevent this form of heat exchange from happening because of the air pocket that is present around.
Answer:
Tornado
Explanation:
A cyclone can last on average for 9 days depending upon the forces of wind leading to the decay of the things. It typically effects an area of typically 30–65 km (20–40 miles). They are characterized by rotating winds around an area of low pressure.
It is a form of cyclone called a Tropical cyclone. It is characterized by heavy thunderstorms where winds circulate in a counterclockwise towards the center of earth. These vigorous winds destruct an area of 50 to 100 miles from the point of their origin. They can last from 12 to 24 hours depending upon the speed of wind.
A thunderstorm is a weather event that can manifest itself in different forms like lightning, Thunder and strong wind, rain, snow. It is a broad term that covers many events like Tornadoes, Floods,Cloud-to-ground lightning and hailing. Depending upon intensity the damage path of a thunderstorm can be from few miles to hundreds of miles.
A Tornado is a specific form of thunderstorm that are characterized by strong, rapidly rotating winds that damages a path from one to fifty miles. They last for less than ten minutes so we can say their duration is less than other deadly weather events.
Therefore, Tornado is best option.
Because it is the main site for digestion. food is totally digested and absorbed in small intestine so it is long.
A mutation is a change in trait. For example people who are lactose intolerant are normal, but people that can can drink milk without a problem have mutated. Hopefully this makes sense and helped.
Answer:
I think it is B
Explanation:
The meaning of abrasion is friction and repeated impact by water, ice or wind.
