Hiya!
An ecosystem is an entire community of living things. They have life cycles, breathe, eat, etc., and all interact with one another. Non-living things, like rocks are dirt, are also a part of an ecosystem. Everything lives in one!
Unfortunately, humans can harm the ecosystem. Fossil fuels, non-renewable resources like coal and oil, killing of animals, and dumping toxic waste can and does harm the ecosystem.
If you found this especially helpful, I'd appreciate if you'd vote me Brainliest for your answer, if other people did not provide a helpful answer (but, I'm sure they did!). I want to be able to assist more users one-on-one! :)
Answer:
392 N
Explanation:
Draw a free body diagram of the rod. There are four forces acting on the rod:
At the wall, you have horizontal and vertical reaction forces, Rx and Ry.
At the other end of the rod (point X), you have the weight of the sign pointing down, mg.
Also at point X, you have the tension in the wire, T, pulling at an angle θ from the -x axis.
Sum of the moments at the wall:
∑τ = Iα
(T sin θ) L − (mg) L = 0
T sin θ − mg = 0
T = mg / sin θ
Given m = 20 kg and θ = 30.0°:
T = (20 kg) (9.8 m/s²) / (sin 30.0°)
T = 392 N
Answer:
orange and red
Explanation: hope this helps lemme know if its correct
<span>the vector diagram should start with a set of x-y axes. From the origin, draw a line down 30 units (miles), and from that point draw a line to the right 18 units. To draw the resultant vector, you simply connect the origin to the final point, making a triangle.</span>
my answer is 1276.7 because I subtracted 88.3 miles and seconds from 1365 MI
