The formulas that will be used are:
Situation one:
The moon will be experiencing gravitational force in the form of centripetal force, so we equate the two formulas.
Gravitational force = GMm /r²
Centripetal force = mv²/r
Equating,
GMm/r² = mv²/r
v² = GM/r
The first scenario will use the formula v² = GM/r
Situation 2:
The second situation will use the simple distance over time formula for velocity, where the distance will be the circumference and the time will be in seconds.
v = 2rπ/t
Answer:
The correct answer is explained below:
Explanation:
- Flooding and intrusion of salt water in the low lying areas can adversely affect human life. This can happen in the following ways:
- Flooding can cause many people to die due to drowning in the flood water.
- Many people lose their habitat and all their belongings due to the entry of water into the settlements having only the ground floors. These people need to rehabilitated to safer regions.
- The saline water percolates through the ground and mixes with the fresh water present in the water table, thereby making them saline and non-consumable.
- People have to face the dearth of food, drinking water, clothes and electricity until rescue operations are sent.
- Increased chance of transmission of water-communicable or water-borne diseases like diarrhoea.
Oxygen, neccessary for cellular respiration, is the answer. As oxygen becomes scarce, your cells begin to aerobically produce very little ATP, in effect fermenting and producing lactic acid.
Answer:
Sertoli cells
Explanation:
The Sertoli cells nourish and protect the developing sperm cells, and spermatogenesis—the developmental pathway from germ cell to mature sperm—occurs in the recesses of the Sertoli cells (Figure 19.17)
