Answer:
0.6... or 3/5
Explanation:
To find the acceleration, we need to use the acceleration formula:
So all we have to do now is plug in the numbers:
Once we divide 60 by 90, we will get the acceleration of the marble.
- 60/90 = 0.6... (repeating)
Our final answer should be:
0.6... or 3/5

As we know,

where,
- m = mass of the object = 0.15 kg
- g = acceleration due to gravity = 9.8 m/s²
- h = height attained by the object = 4 m
let's find the potential energy of that Apple :
Explanation:
The quantity of energy decreases down each trophic level as only 10% of the energy at the upper level is transferred to the next level, the remaining 90% is lost as heat during metabolic process. Through the energy pyramid we can explain how energy is lost at each trophic level, the number of consumer at each trophic level that will benefit from the transfer of energy depends on the size and quality of the energy from the autotrophs
The correct answer is Bacteria can't survive in a hypertonic solution because they lose water.
The 20-30% salt solution is hypertonic as Compared to the bacterial concentration of salt. In this case, the bacteria present in the solution would lose water. Due to excess loss of water, the bacteria would eventually shrink and die. Hence, green olives preserved in the brine would be safe from microbial attack.
Answer:
i only know 2a its to throw/disarge the excess water that soil don't absorb
