Answer:
L = 94.2 ft
n ≈ 5
Explanation:
d = 500 ft
R = 15 ft
The pony walks in one ride around the circle:
L = 2*π*R = 2*3.14*15 ft = 30*π ft = 94.2 ft (One ride around the circle).
In order to determine how many times (n) can the pony give a ride before it needs a drink, we can apply
n = d / L = 500 ft / 94.2 ft = 5.308 ≈ 5
Comets are divided into two types. Long-period comets are the comets that take more than two hundred years to finish an orbit throughout the Sun originate from the Oort Cloud.
<u>Explanation:</u>
- The Oort Cloud has sufficient distance apart of the Sun than the Kuiper Belt, it seems that the Oort Cloud objects were made closer to the Sun than the Kuiper Belt things.
- Long-period comets have highly eccentric orbits.
- The Oort cloud is considered to own a large range commencing from among 2,000 and 5,000 AU to 50,000 AU.
- The chemical makeup of long-period and short-period comets is quite alike.
Its the first one: it supplies radiant energy
Boiling points are raised by hydrogen bonds because they make different molecules desire to "attach" to one another, which requires more energy to do so. In water, for instance, the hydrogen proton is in a state that resembles ionization because the connections between oxygen and hydrogen, while covalent, are strongly polar. The oxygen also receives a partial negative charge. Therefore, hydrogen bonds are formed when the electro-positive H in one molecule is strongly electrostatically attracted to the electro-negative O in nearby molecules. Despite being weak links, they are powerful enough to significantly alter the liquid's characteristics.
