Explanation:
if im not mistaken plant cells go through a stage called photosynthesis meaning the cells can create it's own energy (food) off of water, Co2 and sunlight.
B. By vibrations in wires or strings
Answer:
1248 ft/ sec
Explanation:
Let Q be the position of the observer and let A be the launch point.
Let B = B(t) be the position of the rocket at time t
Also; Let y = y (t)
Let QA be the height of the rocket at time t
We are to find the at a certain time(t) when the distance from Q to the observer is 13000
If we assume an imaginary right-angle triangle QAB ,
Let h be the length of the hypotenuse QB, By using pythagoras Theorem; we have :
h² = 12000² + y²
Differentiating both sides with respect to t ; we have:
----- Equation (1)
where h = 13000
= 480
Replacing it into above equation to find ; we have:
13000 × 480 = 5000 ×
=
= 1248 ft/sec
∴ The rocket is rising fast at the rate of 1248 feet per second.
