There is no image!?...was there meant to be something attached?
16,000 m/s
Since it’s speed, and the distance is unknown. Gravity isn’t applying a noticeable force too on the rocket, as if it were, then the rocket would be accelerating negatively.
Answer:
C. Plants converting sunlight into chemical energy.
Explanation:
An "endothermic reaction" is a process whereby <em>energy coming from the surroundings is being absorbed as heat.</em> This activates the reaction to occur. Since it absorbs the heat to start the reaction, then it can be classified as an endothermic reaction.
When plants convert sunlight into chemical energy, it absorbs the sunlight as a light energy on its chlorophyll. This is where photosynthesis occur. This then results to the chlorophyll reacting with the carbon dioxide, water and the energy which results to the production of <em>oxygen and glucos</em>e.
So, this explains the answer.
Here it is the use of vector and conservation of momentum !
so,
√(16^2+21^2) ×1000= 3000 v
v =8.8 m/s
so answer is B !
if you have any doubt, you can ask ! just comment !
My estimate is 1/2 inch per week.
(0.5 inch/wk) x (1 wk / 7 da) x (1 da / 86,400 sec) x (1 meter / 39.37 inches)
= (0.5 x 1 x 1 x 1) / (7 x 86,400 x 39.37) meter/second
= 1 / 47,621,952 meter/second
= 0.0000000209987... m/s
= 2.1 x 10⁻⁸ meter/second
= 2.1 x 10⁻⁵ mm/sec
= 0.000021 millimeter per second (rounded)
