To see which way atmospheric conditions and meteorological phenomena are moving, and how fast.
Also to see whether they were correct yesterday.
Answer: The global warming is affecting even the most cold places on earth, where we can find the polar ice caps and the glaciers. These places belong to the arctic glacial ocean.
Explanation: In the pass of time, due the human action on the enviroment, the desappear of the polar ice cover are increasing day after day. We, people, are loosing the prime earth air condicioner sistem, which helps to regulate the climate sistem since the entire history of humanity.
In the year of 2018, researches estimated that the total volume of Arctic sea ice in late summer declined, by two estimates, by 75 percent in half a century.
We must know that the decrease of the arctic sea ice have deep effects on the climactic sistem of earth and, considering the polar ice caps desappearence, the sea temperature will increase a lot, due the reflection of ultraviolet rays on the blue ocean, (not anymore on the white ice), transforming what should be the earth air condicioner sistem to a strong heater.
Answer:
The correct option is;
2.26 × 10⁸
Explanation:
The index of refraction, in a medium, n = The speed of light in air/(The speed of light in the medium)
The speed of light = 299792458 m/s
Given that the index of refraction of water = 1.33, we have;
1.33 = 299792458/(The speed of light in water)
The speed of light in water = 299792458/1.33 = 225407863.58 m/s ≈ 2.26 × 10⁸ m/s
The speed of light in water ≈ 2.26 × 10⁸ m/s
Therefore;
v ≈ 2.26 × 10⁸ m/s.
Answer:
True
Explanation:
The heat trasnfer caused by the bulk movement of molecules of fluids is known as convection. Convection has two constituent process advection and diffusion. Examples of natural convection include atmospheric circulation, weather, oceanic circulation, mantle convection etc.
In forced convection the movement of fluid is caused by an external device (source). A fan, pump used to move fluid are external sources that cause fluid movement, the movement of fluid is not happening naturally.
Answer:
C 30 mph
Explanation:
The speed limits in various area's can be concluded as
1. 25- 30 mph in urban residential areas and school districts.
2.55 mph on rural highways, and
3. 70 mph on rural Interstate highways.
so, the correct answer is c
