Answer:
175J
Explanation:
Work done is given by the product of the force applied and the distance travelled as a result of that force.
Or in formula , W=F×d
Thus,
W= 35 × 5.0=175 J or 1.8 e2 J
This makes frequency lower as well as the pitch we hear.
Any non- metal group 13-17
Explanation:
An element from group 2 will form ionic bonds with any non - metal group 13 - 17.
An ionic bond usually forms between metals and non-metals.
- In the main group on the periodic table, metals occupy the first two groups.
- Ionic bonds are formed between two atoms with large electronegativity differences.
- These are simply metals and non-metals.
- The bond forms when metals donates their valence electrons to the non-metals.

Answer:
B
Explanation:
This is an example of single replacement (or single displacement). One element (in this case, C) replaces a similar element in a compound (in this case, the B in AB).
The difference between metal and non-metal in terms of condition is explained below.
Explanation:
- In metals, conduction occurs due to the aggregation of vibrations of molecules and free-electron distribution. While in non-metals, the mechanism for conduction is only atomic or molecular vibrations.
- Apart from free electrons, there are phonons in metals as well as non-metals. Non-metals hold a confined amount of thermal conductivity only due to Phonons and Lattice vibrations.
- Concerning atomic vibration in a solid thing (non-metals mainly), it is easier to know if one receives the fact that atoms are almost floating adjacent to one another depending on the covalent bonds between them.
- When a metal is heated the electrons quickly respond to the heat and transfer it to the nearby atom or solid touching it. As non-metals don't possess free electrons, the heat transfer happens due to phonons (the excited state of the lattice structure vibrating uniformly).
- In metals, this rarely plays a role as the electrons transfer most of the heat efficiently.
