18. Describe the relationship between kinetic energy and mass, and give an example of
lidiya [134]

Answer:

Kinetic energy is directly proportional to mass

Explanation:

Kinetic energy is directly proportional to the mass of an object and also directly proportional to the square of the velocity of that object:

E_k = \frac{1}{2} mv^2

Notice that if we keep velocity constant and only increase the mass of a object, the kinetic energy of that object would increase, as we've already emphasized the direct relationship between the kinetic energy term and the mass term.

Let's take a simple example: assume that object 1 and object 2 are both moving at the same velocity but object 1 has a much lower mass than object 2. According to the equation, object 1 has lower kinetic energy. This object can then transform all of its kinetic energy into some other form, say, heat the ground. The heat transferred will be significantly lower than by the object 2 moving at the same velocity but having a much greater mass.

At pH= 8, which species is most likely to predominate in solution? pKa (-NH3+) = 9.9, pKa (-COOH) = 2.3
PtichkaEL [24]

Answer:

The NH3 + with a PKa = 9.9

Explanation:

The Pka is a mathematical expression to express the dissociation grade of a substance in a solution, that means with a substance with a pKa small is a strong acid, and in this case since the solution pH is 8, that mean that the substance with high pKa ( lower acid strength)  will predominate in a pH of 8.

Improperly maintained landfills result in the release of ________ into the atmosphere
Ket [755]
When landfills have a very poor maintenance, it would likely result in the release of harmful gases into the atmosphere. Among these poisonous gases released are carbon dioxide and methane in which if inhaled in an excessive amount, it could cause respiratory illnesses or it could be fatal.
