Answer:
a. molecular interactions.
Explanation:
Conduction is thermal energy transfer by molecular interactions. Therefore, conduction involves the transfer of electric charge or thermal energy due to the movement of particles. When the conduction relates to electric charge, it is known as electrical conduction while when it relates to thermal energy, it is known as heat conduction.
In the process of heat conduction, thermal energy is usually transferred from fast moving particles to slow moving particles during the collision of these particles. Also, thermal energy is typically transferred between objects that has different degrees of temperature and materials (particles) that are directly in contact with each other but differ in their ability to accept or give up electrons.
Some examples of conductors include metal, steel, aluminum, copper, graphite, etc.
Hence, conduction is thermal energy transfer as a result of the movement of electrons and collision between the molecules of an object.
Answer:
b. False
Explanation:
A centimeter is a hundredth of a meter. This means 1/100 ,1 cm = 0.01 m
A kilo is 1000 grams.
The first answer is false because a hundredth isnot written well.
The second statement is false because the comparison given is of different units of measure. For distance is meters where as for weight is kilograms.

Answer:
time = 224 days
Explanation:
given data
thick = 30 m
piezometers = 280 m
head between two = 1.4 m
aquifer hydraulic conductivity = 50 m
porosity = 20%
solution
we get here average pole velocity that is get by using Darcy law that is
Va = ................1
here Va is average pole velocity and k is hydraulic conductivity and is porosity
here v is = ...........2
v = 50 ×
v = 0.25 m/day
and here average linear velocity Va will be
Va =
Va =
Va = 1.25 m/day
travel time for water will be
time =
time = 224 days
