1. The sun’s thermal energy is exhibited from its surface traveling to the ocean floor in the day

2. As the heat energy is absorbed by the water, the currents move and rise as the ocean waters from the equator heads to the north phase of the planet.

3. And then the waters from the polar areas heads to the south, while ascending and gushing it becomes heated by the sun.

The sun’s gravity also affects this body of water. Since it has a much more stronger gravitation pull than of earth though its far away hence, high tide and low tide tendencies.

The heat moves in predictable ways, flowing from warmer objects to cooler ones, until both reach the same temperature. When air is in contact with the ocean at a different temperature than the sea surface, heat transfer by a conductor. The ocean absorbs and stores energy from the sun and when precipitation falls , it release heat energy in the atmosphere(air)

Five calcite, CaCO3 (MM 100.085 g/mol), samples of equal mass have a total mass of 12.2±0.1 g . What is the average mass and abs

Westkost [7]

Answer:

The average mass of calcium in each sample is: 0.978 g

The absolute uncertainty is: 0.008 g

Explanation:

The absolute uncertainty of the total samples indicated in the statement is ± 0.1 g.

When you multiply or divide quantities with uncertainties, you calculate the final uncertanty by adding the relative uncertainties together.

The relative uncertainty is the absolute uncertainty divided by the quantity:

Relative uncertainty = 0.1g / 12.2 g = 0.008

The average mass of calcium is calculated using proportions, along with the molar masses:

Molar mass of calcium: 40.078 g/ mol (from a periodic table)

Molar mass of calcite: 100.085 g/mol (given)

Proportion:

40.078 g of calcium / 100.085 g of calcite = x / 12.2 g of calcite

x = 12.2 × 40.078 / 100.085 g = 4.89 g calcium

So the total mass of calcium in the five samples is 4.89 g, and the average mass in each sample is:

Average mass = total mass of five samples / number of samples

Average mass = 4.89 g / 5 = 0.978 g of calcium

So, the first answer is that the average mass of calcium in each sample is 0.978 g ( keep 3 signficant figures, such as the quntitiy 12.2 shows, as you have only used multiplication and division).

The absolute uncertainty of each sample is the relative uncertainty multiplied by the average mass of calcium of the five samples, rounded to one decimal:

Absolute uncertainty = 0.978 g × 0.008 ≈ 0.008 g

The answer to the secon question is that the absolute uncertaingy of calcium in each sample is 0.008 g.

Answer:

The correct answer is A)

Overtime, the finches on the island adapted as a result of competition for resources.

Explanation:

The finches beaks adapted to the food source which was favored by natural selection. The successful finches that had the most useful beak for their island survived and therefore reproduced.
