Answer:
1037.56 mph
Explanation:
We are told the distance around the earth which is the circumference is 40075 km.
Converting to miles gives 24901.451 miles
Formula for speed = distance/time
Time for one rotation is 24 hours.
Thus, speed = 24901.451/24 = 1037.56 mph
The properties of aluminium include low density<span> and therefore <u><em>low </em></u></span><u><em>weight</em></u>, <u><em>high strength</em></u>, <u><em>superior malleability</em></u>, <u><em>easy machining</em></u>, <u><em>excellent corrosion resistance</em></u> and <u><em>good thermal and electrical conductivity</em></u><span> are amongst aluminium's most important properties. <u><em>Aluminium is also very easy to recycle.</em></u>
Hope this helps:D
Have a great rest of a brainly day!</span>

Answer:
Nitrogen reacts with oxygen to form a number of nitrogen oxides. It exhibits different oxidation states in its oxides, ranging from +1 to +5. Oxides of nitrogen having nitrogen in the higher oxidation state are more acidic than that in lower oxidation state. Nitrogen oxides are critical components of photochemical smog. They produce the yellowish-brown colour of the smog. In poorly ventilated situations, indoor domestic appliances such as gas stoves and gas or wood heaters can be significant sources of nitrogen oxides.
Following are the harmful effects caused by the oxides of nitrogen
Nitrogen oxides causes irritation in mucous membrane.
Large concentrations of Nitrogen oxide causes lungs problems in humans
It causes injuries to vegetation by damaging leaves.
Nitrogen oxide oxidizes Hydrocarbons in the presence of sunlight, which causes eye irritation, asthama attacks, nasal and throat infections.
