Here we have to point out the necessary character of the substance needed which are used as lightning conductor.
The substance should have the following properties:
High electricity carrying capacity and less resistant.
High melting point
The substance should have high electricity carrying capacity or the resistance is less so that the electricity generated during the lightning easily conducted to the ground
The substance should have high melting point so that during lightning the generated high temperature cannot disrupt the material.
Answer:The lightning rod should be constructed of a metal, which is an inorganic substance.
Metals are good conductors of electricity.

b. Covalent bonds involve the sharing of electrons between atoms; ionic bonds involve the electrical attraction between atoms.
c. Covalent bonds involve the sharing of electrons between atoms; ionic bonds involve the sharing of protons between atoms.
d. Covalent bonds involve the transfer of electrons between atoms; ionic bonds involve the sharing of electrons between atoms.
Final answer:
The difference between covalent bonds and ionic bonds is b. Covalent bonds involve the sharing of electrons between atoms; ionic bonds involve the electrical attraction between atoms.
Final answer:
In covalent bonds, atoms share pairs of electrons to achieve a stable electron configuration. This sharing creates a strong bond between the atoms, and they are typically nonmetals. In ionic bonds, there is a transfer of electrons from one atom to another, resulting in the formation of ions with opposite charges.
One atom becomes positively charged (cation), and the other becomes negatively charged (anion). The electrical attraction between these oppositely charged ions holds them together, forming an ionic bond. Ionic bonds typically form between a metal and a nonmetal.

Select one:
O a. 7.98
Ob.0.263
C. 8.02
O d. 228
Answer:
Option A. 7.98 L.
Explanation:
The following data were obtained from the question:
Initial volume (V1) = 8 L
Initial temperature (T1) = 9.9 °C
Final temperature (T2) = 9.3 °C
Final volume (V2) =..?
Next, we shall convert celsius temperature to Kelvin temperature. This can be achieved as shown below:
Temperature (K) = temperature (°C) + 273
T(K) = T (°C) + 273
Initial temperature (T1) = 9.9 °C
Initial temperature (T1) = 9.9 °C + 273 = 282.9 K
Final temperature (T2) = 9.3 °C
Final temperature (T2) = 9.3 °C + 273 = 282.3 K
Finally, we shall determine the new volume of the gas as follow:
Initial volume (V1) = 8 L
Initial temperature (T1) = 282.9 K
Final temperature (T2) = 282.3 K
Final volume (V2) =..?
V1/T1 = V2/T2
8/282.9 = V2/282.3
Cross multiply
282.9 x V2 = 8 x 282.3
Divide both side by 282.9
V2 = (8 x 282.3)/282.9
V2 = 7.98 L
Therefore, the new volume of the gas is 7.98 L
Answer:
Areas at high latitudes have the coldest water.
Explanation:
Surface water receives its heat from the sun.
I took the test and it was right 100% :)
False
not all forces cause motion
Some forces, like gravity and friction, resist or work against movement.
