Answer:
-People's activities can improve the health of an ecosystem.
-Plants produce food for ecosystems.
-Predators keep ecosystems healthy.
Explanation:
-People can have significant impacts on ecosystems, and while human influence is typically thought of as destructive, we can also help keep an ecosystem healthy by not disrupting natural patterns.
-Plants produce food for many consumers in an ecosystem and are a source of food for large numbers of organisms that exclusively consume plantes.
-Predators are healthy for an ecosystem because they prevent the overpopulation of any one species.
The free body diagram consists of:
1) Weight force, which is a vertical arrow downward
2) A Normal force that is perpendicular to the ramp.
The Normal force can be decomposed in a vertical component and an horizontal component.
The vertical component, Ny, must equal the weight force, due to equilibrium (rest) condiition =>
Ny = weight = m*g = 5.5kg*9.8m/s^2 = 53.9 N
By geometry the vertical component of the Normal force, Ny is such that
cos (angle) = N / Ny => N = Ny * cos(angle)
=> N = 53.9N * cos(angle)
Now use that equation for each option:
a) 0 ° => N = 53.9N * cos(0) = 53.9N
b) 12° => N = 53.9 * cos(12) = 52.7N
c) 25° => N = 53.9 * cos(25) = 48.9N
d) 45° => N = 53.9 * cos(45) = 38.1N
No, because as long as the under ground spring doesn't feed to much, it wont turn into a rain forest
"The New York Times" reported in 2007 that thousands of home built on golf courses are subject to way wards shots. Not every home on a golf course is in the way of errant tee shots. A home built adjacent to a tee box may offer a beautiful views. Living on the course gives an avid golfer more time to practice and play. But a failed golf course could abandonment of the facility, creating an eyesore and declining properties values.
The Tang Dynasty was considered a golden age for art and literature in Chinese history. Two of China's greatest poets, Li Bai and Du Fu, hail from the Tang era.
Woodblock printing, one of the most common ways to print books and other texts, originated during the Han dynasty but further developed during the Tang dynasty.
Buddhism also gained major influence, but later decreased due to being prohibited by the state.
