The book value of a machine, as shown on the balance sheet, is not relevant in a decision concerning the replacement of that mac
KonstantinChe [14]

The book value of a machine, as shown on the balance sheet, is not relevant in a decision concerning the replacement of that machine by another machine: TRUE

<h3>What is the book value?</h3>
  • Book value is the worth of an asset based on its balance sheet account balance in accounting.
  • The value of an asset is determined by subtracting the asset's original cost from any depreciation, amortization, or impairment expenses.
  • Traditionally, a company's book value is equal to its total assets minus intangible assets and liabilities.
  • In practice, however, depending on the source of the computation, book value may include either goodwill or intangible assets, or both.
  • The value inherent in its employees, which is part of a company's intellectual capital, is always overlooked.
  • When intangible assets and goodwill are specifically omitted, the indicator is frequently defined as "tangible book value."

Therefore, the statement "the book value of a machine, as shown on the balance sheet, is not relevant in a decision concerning the replacement of that machine by another machine" is TRUE.

g Oxidation refers to ________ Select one: a. an increase in oxidation number. b. a decrease in oxidation number. c. an increase
mihalych1998 [28]

Answer:

The correct alternative is "Option a".

Explanation:

Oxidation has become a mechanism whereby the physicochemical properties transform attributed to the formation of O₂.

  • The connection involving magnesium as well as O₂ requires the oxidation of the component named magnesium.
  • Even before exposed to the air, silicon is oxidized as well as generates silicon dioxide.

Other possibilities are not connected to the scenario in question. So Choice A is the best option.

The pressure that is the difference between the net hydrostatic pressure and the net colloid osmotic pressure is called
mina [271]

The pressure calculated as the difference between the net hydrostatic pressure and the net colloid osmotic pressure is known as: filtration pressure.

<h3>What is pressure?</h3>

Pressure can be defined as a measure of the force exerted per unit area of an object or body. Thus, it is usually measured in Newton per meter square.

<h3>The types of pressure.</h3>

In Science, there are different types of pressure and these include the following:

  • Hydrostatic pressure
  • Atmospheric pressure
  • Osmotic pressure
  • Filtration pressure

Filtration pressure is a pressure that is typically calculated as the difference between the net hydrostatic pressure and the net colloid osmotic pressure. Also, it promotes the filtration of fluid through a membrane.

If nitrogen-13 has a half life of 2.5 years, how much remains from a 100g sample after 7.5 years
Sonbull [250]

Answer:

12.50g

Explanation:

T½ = 2.5years

No = 100g

N = ?

Time (T) = 7.5 years

To solve this question, we'll have to find the disintegration constant λ first

T½ = In2 / λ

T½ = 0.693 / λ

λ = 0.693 / 2.5

λ = 0.2772

In(N/No) = -λt

N = No* e^-λt

N = 100 * e^-(0.2772*7.5)

N = 100*e^-2.079

N = 100 * 0.125

N = 12.50g

The sample remaining after 7.5 years is 12.50g
