Answer:
0.37 m
Explanation:
The angular frequency, ω, of a loaded spring is related to the period, T, by
The maximum velocity of the oscillation occurs at the equilibrium point and is given by
A is the amplitude or maximum displacement from the equilibrium.
From the the question, T = 0.58 and A = 25 cm = 0.25 m. Taking π as 3.142,
To determine the height we reached, we consider the beginning of the vertical motion as the equilibrium point with velocity, v. Since it is against gravity, acceleration of gravity is negative. At maximum height, the final velocity is 0 m/s. We use the equation
is the final velocity,
is the initial velocity (same as v above), a is acceleration of gravity and h is the height.
The answer to that I think would be D because:
A is wrong because it doesn't make sense the way the order it is in,
B doesn't make sense because it is in the wrong order, and
C says the same exact thing that photosynthesis says which would mean that it is representing the photosynthesis equation not the chemical equation for cellular respiration.
Also it is D because D shows the correct way that the chemical equation representing cellular respiration is supposed to be in.
Hope this helped!
