Answer:

c.The value of T at Recording Station N would be greater than T at Recording Station S.

Explanation:

We can deduce from the information provided that the value of T at recording station N would be greater than T at recording station S.

This problem relates distance with time.

       Speed  = \frac{disance}{time}

                  Distance  = Speed x time

  • Just like any other physical quantity, speed of a substance is directly related to time.
  • The larger the time taken the farther the distance it will cover assuming the velocity is constant.
  • Earthquake waves for example moves at constant speed with a unique velocity in earth materials.
  • The farther the distance, the more time it will take to reach the seismic recording station.
  • Since N is a distance of 200km from the epicenter, it will take a greater time and have a higher reading of T to reach the station.

Nucleosynthesis began when _____ and ended when _____
lutik1710 [3]
<h2>Nucleosynthesis.</h2>

Explanation:

A. the Big Bang occurred; the Big Crunch occurred

Nucleosynthesis is the process by which new atomic nucleus are formed from pre-existing protons and neutrons.

According to cosmic theories, the nucleosythesis began one minute after the occurrence of Big bang and will end with the big Crunch.

The Big bang theory describes all the processes by which the universe came into existence while the big crunch theory explains how universe will come to an end.  A

What is the density of a bar of soap with a mass of 715g, and a volume of 866cm3?
mihalych1998 [28]

Answer:

0.826 g/cm³

Explanation:

density = mass/volume

density = 715 g/866 cm³

density = 0.82564 g/cm³

Rounded to 3 significant figures: 0.826 g/cm³

Enough of a monoprotic acid is dissolved in water to produce a 1.64 M solution. The pH of the resulting solution is 2.82 . Calcu
Lady bird [3.3K]

Answer:

Ka = 1.39x10⁻⁶

Explanation:

A monoprotic acid, HX, will be in equilibrium in an aqueous medium such as:

HX(aq) ⇄ H⁺(aq) + X⁻(aq)

<em>Where Ka is:</em>

Ka = [H⁺] [X⁻] / [HX]

<em>Where [] is the molar concentration in equilibrium of each specie. </em>

The equilibrium is reached when some HX reacts producing H+ and X-, that is:

[HX] = 1.64M - X

[H⁺] = X

[X⁻] = X

As pH is 2.82 = -log [H⁺]:

[H⁺] = 1.51x10⁻³M:

[HX] = 1.64M - 1.51x10⁻³M = 1.638M

[H⁺] = 1.51x10⁻³M

[X⁻] = 1.51x10⁻³M

And Ka is:

Ka = [1.51x10⁻³M] [1.51x10⁻³M] / [1.638M]

<h3>Ka = 1.39x10⁻⁶</h3>
