Answer:
The half-life of carbon-14 is 5730 years, so after 5 half-lives, 5*5730 = 28,650 years will have passed.
The decay of carbon-14 follows an exponential decay curve, so after 5 half-lives, the amount of carbon-14 left will be 1/32 of the original amount.
Therefore, after 5 half-lives, the amount of carbon-14 left will be 1/32 * 600g = 18.75g.
This is the final answer.

Populations grow at different economic rates. Here we classify developing and more developed economies. as we saw previously that there is a third economic category used by the united nations. the least developed. These three stages of economic development are linked to the rate of population growth and quality of life. but we have encounters that are not absolute. The most developed countries offer well-developed government services. These countries have a low birth rate and a low death rate and growth among these countries we have Australia, Japan and Switzerland. developing countries and we have Costa Rica Bulgaria and India. these have a high birth rate and a decrease in the death rate and population growth. The least developed countries have Cambodia, Mali and Togo, these countries have traditional economies that focus on primary industries, such as rural agriculture. They offer few government services, they have a high birth rate and a high death rate, and slow population growth.
The main point of the above paragraph is that the economies of different nations can be classified into three main parts which are underdeveloped, developing, or least developed nations. These three factors are telling of the population growth and quality of life of the people in the nations although this is not always the case.

what is the azimuth orientation (direction) from rockaway beach to the highest point on sweeney ridge
The azimuth is the angle between a celestial body and North, as measured counterclockwise around the observer's horizon (sun, moon).
It establishes the heavenly body's orientation. A celestial body pointed due North, for instance, has an azimuth of 0°, one pointed due East, 90°, 180°, and 270°. A feature's orientation on the surface of the Earth is only determined by azimuth , an angle measurement. Numerous geologic and geographical features have directional orientations. The ability to precisely quantify orientation is particularly helpful for analyzing correlations between various geologic phenomena. azimuth direction of a contact or boundary between two different rock units, for instance, can be measured by geologists. Azimuths or compass bearings are frequently expressed using a system where the zero can be either north or south, and the angle can be measured either clockwise or counterclockwise from the zero. A satellite's position can be direction using the measurements azimuth and elevation. You can face in a certain direction using azimuth, and you can look up into the sky using elevation. Degrees are used to measure both. The range of azimuth is 0° to 360°.

which situation would most likely result in freezing precipitation? rain falling from air which has a temperature of a.
The most likely place for freezing rain and sleet is to the north of warm fronts. The cause of the wintertime mess is a layer of air above freezing aloft. Freezing rain will occur if the warm layer in the atmosphere is deep with only a shallow layer of below freezing air at the surface.
Freezing rain is rain that is kept at temperatures below freezing by the surrounding air mass, causing freezing on contact with surfaces. Unlike rain and snow or ice pellets, freezing rain is entirely composed of liquid droplets.
Raindrops become supercooled while passing through a sub-freezing layer of air hundreds of meters above the ground, and then freeze upon impact with any surface they come into contact with, such as the ground, trees, electrical wires, aircraft, and automobiles. The resulting ice, known as glaze ice, can accumulate to several centimeters in thickness and cover all exposed surfaces.

why does solar energy pass though the greenhouse gases when coming from the sun, but the energy does not easily pass through when radiating from the earth?
When an object or surface is exposed to sunlight, the molecules vibrate more quickly, raising the temperature. In the form of longwave infrared radiation, the heat from the Earth is subsequently expelled into space.
CO2 emissions. You already know that the majority of the Earth's atmosphere is composed of nitrogen and oxygen. transparency to sunlight of several gases They neither emit nor absorb solar or infrared light because they are transparent to outgoing infrared radiation. Because of the greenhouse effect, some infrared light from the Sun is reflected into the atmosphere, but the vast majority is absorbed and reemitted in all directions by clouds and greenhouse gas molecules.
The Earth's surface radiates some of the energy back into space as infrared waves due to the heat from the radiation.

a flat, bench-like surface cut in rock along a coast is a ________.
A narrow flat area that was formed by erosion along the shoreline of a lake, bay, or sea is known as a wave-cut platform.
Wave-cut platforms are frequently most noticeable during low tide, when they are revealed as sizable expanses of flat rock. The platform may occasionally have its landward side covered by sand, creating a beach, and then become invisible except during low tides or storms when the sand is moved.
Wave-cut platforms are created when damaging waves strike the cliff face and create an outbid between the low and high watermarks. This undercut is primarily caused by abrasion, corrosion, and hydraulic action, which results in a wave-cut notch.
Then, this notch grows to become a cave. This section is weakened by the waves until the cave's roof collapses as a result of pressure, freeze-thaw, or biological weathering, which causes the cliff to move away from the shore.
As the collapsed material is broken down into smaller pieces due to attrition and some cliff material may be washed into the sea, the base of the cave shapes the wave-cut platform. This could be dumped at the platform's end to create an offshore beach.
