Answer:
The spotted owl is an example of an indicator species, or an organism that shows the overall health of an environment. This could be an animal, like the owl, a bacterium, a plant, a fish, well you get the idea.
Newton's law of universal gravitation gives the gravitational force between two objects:
F = GMm/r²
F = gravitational force, G = gravitational constant, M & m are the masses of the two objects, r = distance between the objects
Answer:
for example, a person weighing 100kg when on the moon only has 38kg is not wrong because the scale is just a device to measure weight, not mass, people have taken advantage of gravity to measure the weight of objects, so I think Your actual weight doesn't change, what changes is gravity and acceleration
Explanation:
<span>I don't think there is enough information from the question. If you are asked to calculate the number of microbes in a certain area., then it should be that the total area or maybe the volume of that should be given so you can estimate the number of microbes. Hope this helps.</span>
To solve this problem we will apply the concepts related to the Impulse which can be defined as the product between mass and the total change in velocity. That is to say
Here,
m = mass
Change in velocity
As we can see there are two types of velocity at the moment the object makes the impact,
the first would be the initial velocity perpendicular to the wall and the final velocity perpendicular to the wall.
That is to say,
El angulo dado es de 45° y la velocidad de 25, por tanto
The change of sign indicates a change in the direction of the object.
Therefore the impulse would be as
The negative sign indicates that the pulse is in the opposite direction of the initial velocity.
