The satellite image above shows a portion of the Namib Desert in Africa. This is an ancient, sandy desert with dunes that can be

up to 305 m tall. The Namib Desert extends inland from the Atlantic Ocean between 80 km and 200 km and receives only 5 mm to 76 mm of rain each year.
A satellite picture of this same area taken weeks before shows that the shape and location of some sand dunes have changed. Which of these most likely caused the changes in the dunes?

A) Ocean waves
B) Flowing rivers
C) Blowing wind
D) Crustal uplift

Answer:

blowing wind

Explanation:

in a desert there is no water so that cuts the first two out. then for the wind... well there are no mountains or buildings in the desert to block the wind. the last answer, crustial uplift... how often does that happen... =)

Quantum numbers arise naturally from the mathematics used to describe the possible states of an electron in an atom. The four qu
ad-work [718]

Answer:

The allowable values for the principle quantum number (n) are integers greater than zero.

The allowable values for the angular momentum quantum number (l) are integers from 0 to n-1.

The allowable values for the magnetic quantum number (ml) are integers from -l to l.

The allowable values for the spin quantum number (ms) are -1/2 and 1/2.

Explanation:

<em>Identify allowable combinations of quantum numbers for an electron. Select all that apply.</em>

  • <em>The allowable values for the principle quantum number (n) are integers greater than zero. </em>TRUE. The principal quantum number (n) represents the level of energy in which an electron is and can take positive integer values.
  • <em>The allowable values for the angular momentum quantum number (l) are integers from 0 to n-1.</em> TRUE. The angular quantum number (l) represents the sublevel of energy and the kind of orbital an electron is in and can take integer values from 0 to n-1. For instance, if n = 1, l can take the value "0", which represents the sublevel and orbital "s".
  • <em>The allowable values for the magnetic quantum number (ml) are integers from -l to l.</em> TRUE. The magnetic quantum number (ml) represents the orientation of an orbital in space and can take integers values from -l to +l. For instance, if l = 1 (p orbital), ml can take the values -1, 0 and 1, which refer to orbitals px, py and pz.
  • <em>The allowable values for the spin quantum number (ms) are -1/2 and 1/2. </em>TRUE. The spin quantum number (ms) represents the spin of the electron and can take values -1/2 and +1/2.

Calculate the energy in joules and calories required to heat 25.0 g of water from 12.5C to 25.7C
Alex Ar [27]
The heat (Q) required to raise the temp of a substance is:<span>Q=m∗Cp∗ΔT</span><span> where m is the mass of the object (25.0g in this case), Cp is the specific heat capacity of the substance (for water Cp = 1.00cal/gC, or 4.18J/gC,
and Dt is the change in temp.
You'll have to solve this twice, once with the Cp in calories, and once with the Cp in joules.
</span><span>1380.72 Joules</span>
