Correct Answer: To increase the voltage momentarily
Correct Answer: Mandible
Explanation:
The skul contains the bones like Occipital bone, Frontal bone, Mandible, Temporal bone, Parietal bone. The mandible, or jaw bone, is the only movable bone of the skull, forming the temporomandibular joint with the temporal bone. The lower teeth are rooted into the mandible while the upper teeth are rooted in the two maxillae.
Correct Answer: A and D
Correct Answer: gamma - rays
Correct Answer: All of the above
Explanation:
Here all the given compounds have both ionic and covalent bonds.
NaNO3 - In Sodium nitrate, Nitrate is covalently bonded as nitrogen is bonded with 3 oxygen atoms. And this nitrate is ionically bonded with sodium.
CaSO4 - In Calcium sulphate, sulphate is covalently bonded as sulphur is bonded with 4 oxygen atoms. And this sulphate is ionically bonded with calcium.
NH4Cl - In Ammonium chloride, ammonium is covalently bonded as nitrogen is bonded with 4 hydrogen atoms. And this ammonium is ionically bonded with chlorine.
Correct Answer: Compaction and Cementation
Explanation:
The first two steps in the lithification process are Compaction and Cementation.
Correct Answer: All of the above
Explanation:
The nucleus of an atom is the densest part of an atom. It contains the protons and neutrons of an atom.
Correct Answer: C3+ (g) ? C4+ (g) + e-
Explanation:
We know that each successive IE is greater than the previous one, because each ionization process removes one electron and hence increases the total attractive force on the remaining electrons from the nucleus. Hence, C3+ (g) ? C4+ (g) + e- needs more energy.
Correct Answer: Iran
Correct Answer: Bias
