The price of 1 kg of sugar can vary depending on the brand, quality, and location. On average, the cost of 1 kg of sugar is around $1 to $2.
True. The energy released by breaking up 1 kg of uranium (in a nuclear reaction) is equivalent to the energy released by burning approximately 3 million kg of coal (in a combustion reaction). This demonstrates the much higher energy density of nuclear reactions compared to traditional fossil fuel combustion.
Approx. 3 000 t coal (for the complete nuclear fission of 1 kg of the isotope 235U).
I have a figure but this is for 1 kg of Uranium 235, normally reactor fuel is about 4 percent of this isotope, so the amount of coal would be divided by 25 if we are talking about uranium as used in PWR or BWR reactors. Also this figure is for complete use of the U235, whereas for practical reasons of maintaining reactor performance, fuel is unloaded and replaced before it is all used up. So bearing in mind the above, 1 kg of U235 will produce as much energy as 1500 tons of coal. Let's try: 1kg of U235 (3,75%) has 83,14 TJ/kg. 1J=1Ws (3600Ws=1Wh). 1TJ=1000GJ=1 mio MJ 1kg of coal has 6000Wh/kg. I get 3850tons.
When asking the density of a given object, you understand that an object that has a specific gravity (sg) of <1 will sink when placed in water. By processed coal, you may need to see: Bituminous coal (solid): 1346 kg/cu.m. Bituminous coal (broken): 833 kg/cu.m. Anthracite coal (broken): 1105 kg/cu.m. Anthracite coal (solid): 1506 kg/cu.m. The energy density of coal--in other words its heating value-- is 24 megajoules per kilogram. (Note that one kilowatt-hour is 3.6 megajoules.
1 kg
If 1 kg of tomatoes costs 5 CHF, 0.1 kg will cost 1/10th of 5 CHF, so the cost will be 0.5 kg.
i dont no
2.2 POUNDS
130
depends where you buy it! LOL
1 kg of 235U = 3 000 t coal

8 is the answer . Since half a kg is 500g, 100 g would cost 1/5 as much. 1/5 of 40 is 8.
There are 1 Million mg in 1 kg.. so $120.00/1,000,000 = $0.00012
density of coal is Coal, Anthracite, solid 1506 kg/cu.m Coal, Anthracite, broken 1105 Coal, Bituminous, solid 1346 Coal, Bituminous, broken 833 using a median value of 900 kg/m3 1 gal (US) = 0.00378 m3 weight of 1 gal = 900 x 0.00378 = 3.407 kg or 7.51 pounds
