Brandon ice skates with his family at a local park every winter. Last summer, he noticed the pond he was fishing in was in the e

xact location of the ice skating rink. Which best explains why this is possible?
A. a slab of concrete is placed over the pond and covered with ice each winter for skating

B. bulldozers break the ice down after each winter and the pond is filled with water for the summer

C. the fish hatch under the frozen water and their movement causes the ice to break down into water again

D. the water is frozen solid as the temperature drops each winter and the ice melts when the temperature increases again

A is possible but unlikely as the concrete will be HUGE!

B is also unlikely as the ice will melt as it is broken down by bulldozers n turn into water!

C is impossible as it requires a LOT of fish.

D. the water is frozen solid as the temperature drops each winter and the ice melts when the temperature increases again is the best explanation.

Hi There!

A. a slab of concrete is placed over the pond and covered with ice each winter for skating (Incorrect, because if there was a slab of concrete of the ice the ice would have already melted before he even got there.)

B. bulldozers break the ice down after each winter and the pond is filled with water for the summer (Incorrect, bulldozers are way to heavy and they wold have feel in the ice the melting of ice is a natural occurrence.)

C. the fish hatch under the frozen water and their movement causes the ice to break down into water again (Incorrect, because fish eggs don't hatch when its cold.)

D. the water is frozen solid as the temperature drops each winter and the ice melts when the temperature increases again (Correct, because ice melts when the temperatures raises.)

Hope This Helps :)

The density of silver is 10.5 g cm3. a piece of silver with a mass of 61.3 g would ovvupy a volume of ?
natali 33 [55]
The relationship between mass m, volume V and density d is:
d= \frac{m}{V}
The silver has density d=10.5 g/cm^3, and the mass of the piece of silver is m=61.3 g. Therefore we can calculate its volume using the previous formula:
V= \frac{m}{d}= \frac{61.3 g}{10.5 g/cm^3}=5.84 cm^3

1. why did aristarchus choose the time of a half (quarter) moon to make his measurements for calculating the earth-sun distance?
Stells [14]

In order to make his measurements for determining the Earth-Sun distance, Aristarchus waited for the Moon's phase to be exactly half full while the Sun was still visible in the sky. For this reason, he chose the time of a half (quarter) moon.

<h3 /><h3>How did Aristarchus calculate the distance to the Sun?</h3>

It was now possible for another Greek astronomer, Aristarchus, to attempt to determine the Earth's distance from the Sun after learning the distance to the Moon. Aristarchus discovered that the Moon, the Earth, and the Sun formed a right triangle when they were all equally illuminated. Now that he was aware of the distance between the Earth and the Moon, all he needed to know to calculate the Sun's distance was the current angle between the Moon and the Sun. It was a wonderful argument that was weakened by scant evidence. Aristarchus calculated this angle to be 87 degrees using only his eyes, which was not far off from the actual number of 89.83 degrees. But when there are significant distances involved, even slight inaccuracies might suddenly become significant. His outcome was more than a thousand times off.

A bird is about 6.26.2 in.​ long, with a​ thin, dark bill and a​ wide, white wing stripe. If the bird can fly 9292 mi with the w
Trava [24]

Answer:

209 mph

Explanation:

V = Speed of bird in still air

v = Speed of wind = 44 mph

Consider the motion of the bird with the wind

D_{1} = distance traveled with the wind = 9292 mi

t_{1} = time taken to travel the distance with wind

Time taken to travel the distance with wind is given as

t_{1} = \frac{D_{1}}{V + v}

t_{1} = \frac{9292}{V + 44}                              eq-1

Consider the motion of the bird with the wind

D_{2} = distance traveled against the wind = 6060 mi

t_{2} = time taken to travel the distance against wind

Time taken to travel the distance against wind is given as

t_{2} = \frac{D_{2}}{V + v}

t_{2} = \frac{6060}{V - 44}                              eq-2

As per the question,

Time taken with the wind = Time taken against the wind

t_{1} = t_{2}

\frac{9292}{V + 44} = \frac{6060}{V - 44}

(9292) (V - 44) = (6060) (V + 44)

9292V - 408848 = 6060V + 266640

3232V = 675488

V = 209 mph
