Ionic bonding is a type of bonding in which electrostatic attraction is predominant. In ionic bonding, electrons are transferred from one atom to another, creating positively charged ions (cations) and negatively charged ions (anions). The electrostatic attraction between these oppositely charged ions holds them together, forming a strong bond. This type of bonding typically occurs between a metal and a nonmetal.
Elements numbered 58 to 71 in the periodic table are called lanthanons. Lanthanons are a group of elements that belong to the Lanthanide series. They are characterized by their similar properties and location in the periodic table. These elements are known for their high reactivity and are commonly used in various industrial and technological applications.
Among the provided options:
The closest option is 0.05
cm/min
0.05cm/min. Therefore, the hydraulic conductivity of the soil is approximately
0.05

0.05cm/min.
The closest option is 350,000 psi. Therefore, the modulus of elasticity of the composite material is approximately 350,000psi.
When rolling two six-sided dice, each die can show a number from 1 to 6. The possible combinations of the two dice can be represented as a matrix, where each cell represents the outcome of one die (assuming fair six-sided dice):
To get a sum of 5, there are only four possible outcomes: (1, 4), (2, 3), (3, 2), and (4, 1). Out of the total 36 possible outcomes when rolling two dice (6 faces on the first die times 6 faces on the second die), the probability of rolling a sum of 5 is:

Cohesion refers to the attraction between like molecules. It is the force that holds molecules of the same substance together. In this context, the correct answer is cohesion because it accurately describes the attraction between like molecules. Adhesion, on the other hand, refers to the attraction between unlike molecules, reduction is the process of decreasing something, and conduction refers to the transfer of heat or electricity through a substance.
Gray iron is considered as the general purpose, oldest type, and widely used cast iron. It is known for its excellent castability, good machinability, and high wear resistance. Gray iron gets its name from the gray color of its fracture surface, which is caused by the presence of graphite flakes in its microstructure. This type of cast iron is commonly used in applications such as engine blocks, pipes, and automotive components.
To find the total distance traveled by the truck before coming to rest, we can use the kinematic equation for uniformly decelerated motion.
The negative sign indicates the direction of motion. The total distance traveled by the truck before coming to rest is 20 meters.
