It is a natural adaptation during winter (possibly due to the cold) that they lose their leaves to conserve water....
hope this helps:)
To reach a vertical height of 13.8 ft against gravity, which has an acceleration of 32 ft/s^2, the required vertical speed can be calculated from the equation:
vi^2 - vf^2 = 2*g*h
Given that it has vf = 0 (it is not moving vertically at its maximum height), g = 32, and h = 13.8, we can solve for vi:
vi^2 = 29.72 ft/s
This is only its vertical speed, so this is equivalent to its original speed multiplied by the sine of the angle:
29.72 ft/s = (v_original)*(sin 42.2<span>°</span>)
v_original = 44.24 ft/s
Converting to m/s, this can be divided by 3.28 to get 13.49 m/s.
Dark energy is what is causing the accelerating expansion of the universe. It can also be defined as the theoretical energy that counteracts or acts against gravity. Others also define it as a theoretical, new kind of dynamic energy field that fills space, but whose energy has an effect opposite to that of normal energy.
Answer:
ice forming and then melting back into water
Answer:
Workdone = 40 Nm
Explanation:
Force = 20 Newton
Distance = 2 meters
To find the work done;
Mathematically, work done is given by the formula;
Workdone = force * distance
Workdone = 20 * 2
Substituting into the formula, we have;
Workdone = 40 Nm
