Answer:
2:3
Explanation:
The compound whose chemical formula is given in the question is called Aluminium oxide. It is structurally made up of two atoms of aluminum (Al) and three atoms of oxygen (O).
Based on the above, the atomic ratio of aluminum to oxygen can be calculated as 2:3 i.e. 2 atoms of aluminum to 3 atoms of oxygen.
At 37°C, the pH of distilled water is actually around 6.8, which means the human extracellular fluid is quite alkaline. However, the intracellular pH of the warm-blooded human is still around 6.8. This has been confirmed by various destructive and non-destructive measurements.

Answer:
<em>The type of vegetation a surface does affect the </em><em>water coming from above to sink in or runoff. </em>
Explanation:
This is how the vegetation affects the runoff:-
The leaves and stems present in the vegetation do not let the water fall directly on the soil and makes the process rather slow which makes the water to get to the ground slowly and sink in properly inside the soil rather than running off.
If the vegetation present is dense with there was being hairy then also the water would not run out and will get absorbed by the roots letting the soil intact
Answer: Potential energy is converted to kinetic energy and back again.
Explanation:At points 1 and 3, the pendulum stops moving, and its mechanical energy is purely potential. At point 2, the pendulum is moving the fastest, and its mechanical energy is purely kinetic. Therefore, as the pendulum moves from point 1 to point 3, its potential energy is first converted to kinetic energy, then back to potential.
