Answer: The saltiest locations in the ocean are the regions where evaporation is highest or in large bodies of water where there is no outlet into the ocean. The saltiest ocean water is in the Red Sea and in the Persian Gulf region (around 40‰) due to very high evaporation and little fresh water inflow.
Explanation: Sea water salinity is expressed as a ratio of salt (in grams) to liter of water. In sea water there is typically close to 35 grams of dissolved salts in each liter. It is written as 35‰ The normal range of ocean salinity ranges between 33-37 grams per liter (33‰ - 37‰).But as in weather, where there are areas of high and low pressure, there are areas of high and low salinity. Of the five ocean basins, the Atlantic Ocean is the saltiest. On average, there is a distinct decrease of salinity near the equator and at both poles, although for different reasons.Near the equator, the tropics receive the most rain on a consistent basis. As a result, the fresh water falling into the ocean helps decrease the salinity of the surface water in that region. As one move toward the poles, the region of rain decreases and with less rain and more sunshine, evaporation increases.Fresh water, in the form of water vapor, moves from the ocean to the atmosphere through evaporation causing the higher salinity. Toward the poles, fresh water from melting ice decreases the surface salinity once again. Water has a unique property. As the temperature decreases to 40°F (4°C) the molecules slow, water contracts and the density increases. Below 40°F (4°C) the molecules begin to bond to each other and as they do, the water begins to expand again, decreasing the density. At 32°F (0°C) all molecules are locked into a crystalline structure with a resulting nine percent expansion in size. This expansion, and corresponding decrease in density, is the reason ice floats. The amount of salt in sea water also determines the temperature at which sea water freezes. Adding salt to water lowers the freezing temperature. Water with a salinity of 17‰ freezes at about 30°F (-1°C) and 35‰ water freezes at about 28.5°F (-2°C). Yet, despite the saltiness of the ocean, sea ice contains very little salt, about a tenth of the amount of salt that sea water has. This is because ice will not incorporate sea salt into its crystal structure. Therefore, sea ice is actually drinkable. The temperature and salinity of the sea water also help determine its density. As the temperature of sea water decreases the density also increases. Also, as the salt content of sea water increases, so does its density. This makes the density of sea water, unlike fresh water, below the freezing point. So, in situations of sea ice formation, the salinity, and therefore the density of the underlying water continues to increase well after an area is iced over.
In the "Average Salinity" map (below), it shows the lowest salinity in the polar regions. Bear in mind, this image depicts surface salinity only. The surface salinity is lower in the polar regions than in the tropical regions due to melting each summer. However, each winter below the ocean surface, the increased salinity in the water due to ice formation, causes the water below the ice to sink and that sinking motion governs the motion of the ocean's deep-water currents.

Materials that can be magnetized, which are also the ones that are strongly attracted to a magnet, are called ferromagnetic (or ferrimagnetic). These include the elements iron, nickel, and cobalt, and their alloys, some alloys of rare-earth metals, and some naturally occurring minerals such as lodestone.
Gravitational force is is a force that attracts two objects with mass. We call the gravitational force attractive because it always tries to pull masses together, it never pushes them apart. Every object, including you, is pulling on every other object in the entire universe!
An example of gravitational force in the real world is the force that holds the gases in the sun. The force that causes a ball you throw in the air to come down again. The force that keeps the Earth and all of the planets in line in the proper position in their orbits around the sun.

Archaeologists have discovered the legendary Golden Igloo of the Pribiloff Islands, a structure consisting of a
halfspherical shell with an inner diameter of 1.25 m and an out diameter of 1.45 m. What is the value of this antiquity,
given that gold currently sells for $1,263/ounce and has a density of 19.3 g/cm3? (Note that 1 ounce = 31.1034768 g)
Answers
Answer:
The value of the Golden Igloo is $227.4 million.
Explanation:
First, we need to find the inner and the outer volume of the half-spherical shell:
[tex] V_{i} = \frac{1}{2}*\frac{4}{3}\pi r_{i}^{3} [/tex]
[tex] V_{o} = \frac{1}{2}*\frac{4}{3}\pi r_{o}^{3} [/tex]
The total volume is given by:
[tex] V_{T} = V_{o} - V_{i} [/tex]
Where:
[tex] V_{i} [/tex]: is the inner volume
[tex]r_{i}[/tex]: is the inner radius = 1.25/2 = 0.625 m
[tex] V_{o} [/tex]: is the outer volume
[tex]r_{o}[/tex]: is the outer radius = 1.45/2 = 0.725 m
Then, the total volume of the Igloo is:
[tex] V_{T} = \frac{2}{3}\pi r_{o}^{3} - \frac{2}{3}\pi r_{i}^{3} = \frac{2}{3}\pi [(0.725 m)^{3} - (0.625 m)^{3}] = 0.29 m^{3} [/tex]
Now, by using the density we can find the mass of the Igloo:
[tex] m = 19.3 \frac{g}{cm^{3}}*0.29 m^{3}*\frac{(100 cm)^{3}}{1 m^{3}} = 5.60 \cdot 10^{6} g [/tex]
Finally, the value (V) of the antiquity is:
[tex] V = \frac{\$ 1263}{oz}*5.60 \cdot 10^{6} g*\frac{1 oz}{31.1034768 g} = \$ 227.4 \cdot 10^{6} [/tex]
Therefore, the value of the Golden Igloo is $227.4 million.

Microwave radiation is absorbed by the water in food. As the water absorbs the heat it causes the food to get hot. If the wavelength of a microwave is 10, calculate the frequency and the energy of each photon.
Answers
Answer:
1) The frequency of each photon is 3.0 × 10⁹ Hz
2) The energy of each photon is 1.98786 × 10⁻²⁴ J
Explanation:
The energy, 'E', in a photon of light is given by Planck's equation as follows;
E = h·f = h·c/λ
Where;
E = The energy of a photon
h = Planck constant = 6.6262 × 10⁻³⁴ J·s
f = The frequency of the photon/radiation
c = The speed of light = 3.0 × 10⁸ m/s
λ = The wavelength of the photon/radiation
The given parameters of the microwave are;
The wavelength, λ = 10 cm = 0.1 m
The type of wave = Microwave
1) From E = h·f = h·c/λ, we find that the frequency, 'f' equals c/λ
∴ f = 3.0 × 10⁸ m/s/(0.1 m) = 3.0 × 10⁹ 1/s = 3.0 × 10⁹ Hz
The frequency of each photon, f = 3.0 × 10⁹ Hz
2) From E = h·f = h·c/λ, the energy, 'E', of each photon is given as follows;
E = h·c/λ = 6.6262 × 10⁻³⁴ J·s × 3.0 × 10⁸ m/s/(0.1 m) = 1.98786 × 10⁻²⁴ J
The energy of each photon, E = 1.98786 × 10⁻²⁴ J
