Answer:
D. Phototropism
Explanation:
Plants, like every other living organism, responds to external stimulus. In this question, the stimulus is LIGHT from the sun entering through the window sill. The plant is responding positively to the light stimuli by growing towards the direction where the light is coming from. This exhibit is called PHOTOTROPISM.
Phototropism, comes from two words viz photo- meaning light and tropism- meaning movement. Hence, phototropism is the growth of an organism (plant in this case) in response to a light stimulus. The case described in this question is POSITIVE PHOTOTROPISM because the growth occurs towards the light source.
Answer:
14.5L
Explanation:
The following data were obtained from the question:
V1 = 14.1L
T1 = 13.9°C = 13.9 + 273 = 286.9K
T2 = 22°C = 22 + 273 = 295K
V2 =?
Using charles' law: V1/T1 = V2 /T2, we can obtain the new volume as follows:
14.1/286.9 = V2 /295
Cross multiply to express in linear form
286.9 x V2 = 14.1 x 295
Divide both side by 286.9
V2 = (14.1 x 295) / 286.9
V2 = 14.5L
Therefore, the new volume = 14.5L
Technology is anything made my man to make tasks easier. So yes, a screwdriver is technology.
Answer:
None of the options are correct. The correct answer is 30020J
Explanation:
Data obtained from the question include:
Mass (M) = 2000g
Initial temperature (T1) = 10°C
Final temperature (T2) = 29°C
Change in temperature (ΔT) = T2 - T1 = 29°C - 10°C = 19°C
Heat (Q) =?
Specific heat capacity (C) of granite = 0.79J/g°C
Applying the equation Q = MCΔT, the heat absorbed by the granite rock can be obtained as follow:
Q = MCΔT
Q = 2000 x 0.79 x 19
Q = 30020J
Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.
<span>3O2(g) <--> 2O3(g);
Keq = 1 = [O3]^2/[O2]^3
So [O2]^3 = [O3]^2
Thus A) is correct</span>
