Question
The metal in a chunk of copper or iron is composed of amorphous particles. non-crystalline fibers crystals none of the above when a chocolate bar is cut in half, its density is doubled halved unchanged compared to the volume of a kilogram of the volume of a kilogram of lead is more less the same the density of a2 cubic meter block of mass of 1000 kg is 100 kg/m^3 a metal block has a density of 5000 kg per cubic meter and a volume of 2 cubic meters. what is the block's mass 5000 kg 2500 kg 10, 000 kg 1000 kg none of the above.Explanation / Answer
1) The metal in a chunk of copper or iron are composed of crystals. Therefore, option C is correct.
2) Density remains same. Therefore, option C is correct.
3) volume = mass/density.
Feathers have lower density as compared to lead. Therefore, for a given value of mass, a substance with higher density will occupy lower volume. Therefore, volume of 1 kg of lead will be less than the volume of 1 kg of feathers. Hence, option B is correct.
4) density = mass/volume
If the mass is doubled keeping the volume same, density will be doubled. Therefore, option A is correct.
5) density = 1000 kg / 2 m^3 = 500 kg/m^3. Therefore, option D is correct.
6) mass = density * volume = 5000 kg/m^3 * 2 m^3 = 10,000 kg. Therefore, option C is correct.
7) Steel ball is more elastic. Therefore, option A is correct.
