<span>Here are a few of the fundamental words in ecology, which are simple, but may be easy to mix up because they are so similar. It is, however, quite important to be clear of what they mean. I will here try to explain how they differ by defining them and giving a few examples to illustrate how they could be applied.
</span>
<span>A habitat is basically the site<span> where an organism or a group lives</span>. It may be anything from a stone in a lake, on which algae grows, to a forest containing all sorts of creatures. Note that groups within a habitat do not need to be of the same species. However, one usually speaks of habitats of individuals, species, or larger groups. For instance, the habitat of the algae would be the stone in the lake, and the forest could be the habitat of a single bear – regardless of what other organisms live there and how they are geographically distributed; here we are interested in the bear, so we define the habitat as its home range, and all that falls within it will arbitrarily be a apart of its habitat. hope this helps</span>
Honed I don’t know where the question is
Answer:
1. An object will remain still unless tampered by an external force.
2. Force = change in Momentum * Acceleration
3. For every action, there is an equal and opposite re-action.
Explanation:
Answer:
0.4
Explanation:
A concave lens is a diverging lens, so it will always have a negative focal length. Image distance is always negative for a concave lens because it forms virtual images.
From the lens formula;
1/f = 1/u+ 1/v
- 1/2 = 1/3 - 1/v
1/v = 1/3 + 1/2
v= 6/5
v= 1.2 cm
Magnification = image distance/object distance
Magnification = 1.2cm/3cm
Magnification = 0.4
22 ft/s^2.
explanation: In this case, the velocity has increased by 60 mph in 4 seconds, so the average increase is 60/4 = 15 mph every second, or 15 mph/s.
Usually, you will want to use the same units of time throughout. In this case, you could multiply by the number of seconds in an hour to find out the change in velocity if it carried on travelling for that length of time. This would give the acceleration in units of mph/h, or mph^2.
If you want the answer in feet/s^2, then take your 15 mph/s answer, multiply by the number of feet in a mile (to get it to feet per hour per second) then divide by the number of seconds in an hour to get it to feet per second per second, or feet/s^2.
You should get 22 ft/s^2.
