Answer:
Birds in different areas were exposed to different food sources.
Explanation:Im almost 100 percent this is it.
The plus direction is going to go with the 10N to the right. Since the second force is applied in exactly the opposite direction, the net force 10 - 3 = 7 newtons to the right.
Answer:
78.4 J
Explanation:
Given:
Mass of the object (m) = 2.0 kg
Height or displacement of the mass (h) = 4.0 m
Now, change in gravitational potential energy (ΔU) = ?
Change in gravitational potential energy of an object is the energy stored by the object when it is raised to some height above the reference ground level.
Change in gravitational potential energy of an object of mass 'm' raised to a height 'h' above the ground is given as:
![\Delta U=mgh](https://tex.z-dn.net/?f=%5CDelta%20U%3Dmgh)
Where, 'g' is the acceleration due to gravity and has a value of 9.8 m/s².
Now, plug in all the given values and solve for ΔU. This gives,
![\Delta U=(2.0\ kg)(9.8\ m/s^2)(4.0\ m)\\\\\Delta U=78.4\ J](https://tex.z-dn.net/?f=%5CDelta%20U%3D%282.0%5C%20kg%29%289.8%5C%20m%2Fs%5E2%29%284.0%5C%20m%29%5C%5C%5C%5C%5CDelta%20U%3D78.4%5C%20J)
Therefore, the change in gravitational potential energy is 78.4 J.
Not sure if this is what your looking for, but hope it helps. Nitrogen gas can be changed into nitrogen compound through nitrogen fixation, which is the conversion of nitrogen gas to ammonia, that are absorbed by the plant to make protein. Another way is through animals eating plants and obtaining nitrogen, which is later released, by decomposes, when the organism dies.
