To determine how long the black bear will run, the distance it will travel must first be determined. Thus, the proposed calculation must be solved.

1.95 x 10 ^ 4

1.95 x 10 x 10 x 10 x 10

19.5 x 10 x 10 x 10

195 x 10 x 10

1950 x 10

19500

Thus, the bear will run 19,500 miles, so, running at 35 mph, it will take about 557 hours to run that distance (19,500 / 35).

Answer:

A: They bring cool air.

Explanation:

Took the test and got it correct. :)

Jet streams are fast flowing meandering air currents. Polar jet streams bring cool air through the atmosphere. Polar jets meet subtropical jets at some regions.

The polar jet stream, which travels through the lower layers of the atmosphere in the Northern Hemisphere, is a swiftly moving band of westerly winds.

The confluence of warm air ascending from the tropics and cold air masses descending from the arctic produces the jet. The denser cold air lowers and deflects the warmer air areas north, creating deep troughs and steep ridges that give the jet stream its wavy appearance.

As pockets of cold air intermittently sneak down from the Arctic, this pattern spreads across the mid-latitudes of North America, Europe, and Asia, producing opposing waves and flows that speed eastward due to the earth's rotation.

The two properties which can be measured from the given information are streak and cleavage of the mineral.

Minerals are naturally forming inorganic substances having crystal structure and metallic characteristics. They have a definite chemical composition and  homogeneity.

Streak is the color of powder form of mineral and cleavage is how the mineral cleave when we cut through a plane.  Hardness says how much hard the solid is.

When the mineral breaks into cubes when struck with a hammer, we measure its cleavage properties. The red trail on scrapping indicates the streak of the mineral.

Hence, the two properties we can measure from breaking by hammer and scrapping by an unglazed porcelain are its cleavage and streak.

the last one, (A zinc, Zn, atom contains 30 protons inside the nucleus and 30 electrons outside the nucleus)

A zinc, Zn, atom contains 30 protons inside the nucleus and 30 electrons outside the nucleus accurately describes the atoms of a specific element ,therefore option (d) is correct.

Zinc is placed in group 12 of the periodic table. It is in the first period of transition or d block elements, and fourth period of the periodic table.

Zinc is a metal. It has two valence electrons that are lost easily. Zinc forms positive ions with 2+ charges, like the metals of the alkaline earth family.

Answer:

Since we are adding more water to an alcohol solution,

the volume of alcohol in the alcohol will be the same but the volume percent of alcohol will decrease

Initial Volume of Alcohol in the solution:

We are given that 70% of the 2.1 mL solution is alcohol

So, Finding 70% of 2.1

70/100 * 2.1 = 1.470 mL alcohol

Volume of Water in the Solution:

In our initial solution, we have (2.1 - 1.47) mL water

and we add an additional 6.7 mL water in the solution

Hence,

the total amount of water in the solution = (2.1- 1.47) + 6.7

Total amount of water in the solution  = 0.63 + 6.7

Total amount of water in the solution = 7.33 mL

Volume of the final solution = 8.8mL

Percent Alcohol in the new mixture:

Now that we know the volume of alcohol and the volume of water in our mixture, we can now find the percent composition of alcohol

Percent of alcohol (%v/v) = Amount of alcohol / 100mL of solution

Percent of alcohol = (1.47 / 8.8) * 100

Percent of alcohol = 0.167 * 100

Percent of alcohol = 16.7

Therefore, in a 100mL solution, we will have 16.7 mL alcohol

Explanation:

The azimuthal quantum number and magnetic quantum number corresponds to the s orbital is zero. Hence, there is only one m value and thus contains one orbital only.

The quantum numbers are numbers used to describe the position of an electron within an orbital. The principal quantum number n indicates the main energy level. The azimuthal quantum number l indicates the shape and type of orbital which have values from 0 to n-1.

The magnetic quantum number m indicates the number of orbitals for a sublevel. m can have values from + l to -l. The fourth quantum number s is called spin quantum number. For an electron the spin quantum number can be +1/2 or -1/2.

The n value for the 6s sublevel is 6. The azimuthal quantum number , l for an s orbital  is zero. So its m quantum number has only one value that is zero. Hence, there is only one orbital in 6s sublevel.
