Answer:
1-b
2-weaker(option is incorrect)
3-a
Explanation:
1-b because iodine is more electronegative because of this negative on iodine will be more stable as negative charge on more electronegative element is more stable.
2-weaker as size of Te (Tellurium) is greater than S (sulphur) so bond length of H-Te is larger than H-S and therefore bond energy will be lesser and can easily give hydrogen in case of H-Te. as bond energy is inversly proportional to bond length.
3-a hydrogen has more negative electron affinity so hydrogen will have -1 charge and it will behave as a electron donar atom that is basic not acidic hence NaH is not acidic.
Gas particles are in constant motion, and any object in motion has kinetic energy
Answer: Mechanical waves can be Longitudinal or Transverse.
Explanation: So... a mechanical wave is a kind of wave that is a oscillation of matter. Mechanical waves can also transfer energy. However, while it still can transfer over long distances, the wave is limited. it means that the oscillation material is limited. A mechanical wave can be a transverse wave or a longitudinal wave or a surface wave. but since there is only Longitudinal or Transverse that should be your answer.
A transverse wave, its a wave that particles move up and down.
A Longitudinal wave is a wave that moves back and forth.
