If a car is traveling 27 meters in 3 seconds, what is its speed?

Compare the light gathering power of a 1 meter diameter telescope to that of the human eye ,which has a diameter of roughly 2.5

lesantik [10]

Answer:

The telescope can gather light 1600 times more than the human eyes can!

Explanation:

The light gathering ability of an optical element is directly proportional to its area of opening.

So, in comparing the light gathering abilities for two objects, it is just the ratio of their area of opening.

Let the diameter of the telescope be D = 1 m

And the diameter of the human eyes be d = 2.5 cm = 0.025 m

Light gathering ability of the telescope compared to the eyes = D² ÷ d²

= (D²/d²) = (1²/0.025²) = 1600 times.

The telescope can gather light 1600 times more than the human eyes can!

Hope this Helps!!!

Five locations are marked on the world map. Which location is most prone to hurricanes?

Kruka [31]

Answer: A is the spot that is prone to hurricane mostly.

Explanation:

The locations on the world map spot A, B, C, D, E are regions with country prone to hurricane.

The SPOT A, is GULF of Mexico, an ocean basin closer to the Atlantic ocean, surrounded with the North American continent, the Hawaiian island is also within that region.

The SPOT B, is the southern Pacific ocean with countries like BRAZIL, PERU, ECUADOR, CHILE, in that same region. This is also visited by the hurricane.

The SPOT C, is within the regions of AFRICA, countries at the edge are also affected by hurricane.

The SPOT D, is Asian continent with Russia at the edge. They are also prone to hurricane.

The SPOT E, is the North Pacific ocean region located at the top left hand side of the world map, with countries like Canada, Alaska and co. Close to the artic circle.

With the observation of all this spot, THE SPOT A, is most prone to hurricane, and its effect are very high there....

Country thee are greatly affected by it,
