Answer:
f = 80 flutter/ second
T= 0.0125 sec
Explanation:
Given data:
Fluttering of wings = 4800 time per minute
Frequency of wings = ?
Period for one wing in sec = ?
Solution:
There are 60 seconds in one minute, thus frequency of wings
4800/60 = 80 flutter per second
Period:
T = 1/f
T = 1/80
T= 0.0125 sec
Grasses can grow where they could not earlier because the soil conditions, water volume, or rate of sunlight have evolved.
Each species of plant requires specific conditions to thrive. These conditions include:
- Nutrients from the soil.
- Sunlight
- Specific amount of water.
This implies that if the conditions for a specific species are not provided in terms of sunlight, radiation, and water, the plant will not grow in that specific zone. In the same way, if the conditions of a zone change and they are not suitable for a plant species the plant will grow even if this was not possible before.
This key idea is the reason why some plants including grasses can now grow in zones where they did not exist before. Some of the factors that have contributed to this are:
- Fertilization: This provides soils with necessary nutrients.
- Climate change: This has affected climate patterns, and therefore it can increase or decrease radiation.
- Irrigation: This increases the amount of water available for plants.

Puede tomar los valores enteros positivos: n= 1, 2, 3, 4, 5, 6, 7. Por ejemplo si tengo un elemento químico que su último nivel es el 3s, su número cuántico principal sería el 3. Si tengo un elemento químico en que su último nivel es el 1s, entonces su número cuántico principal sería 1.
It would be 399.88 g/mol.
