Wave speed = (frequency) x (wavelength)
= (5 / second) x (30 mm)
= 150 mm/second = 0.15 meter/second .
Answer:
Distance = 85.3 miles
displacement = 0
Explanation:
The total distance covered to grandma's house is 42.6 miles as recorded by the odometer. The same distance would be covered when returning to the base. Hence;
Total distance for the round trip = 42.6 + 42.6 = 85.2 miles
Since the trip was a round trip, the displacement is zero because the family returned to their initial location.
Correct answer is Availability of soil minerals.
There are two types of limiting factors that affect plant population in a ecosystem. They are:
- Biotic
- Abiotic
Biotic factors includes food, diseases etc. Such as Invasive weed species, seed dispersal by wind, disease-causing fungal spores are examples of biotic limiting factor.
Abiotic factors include sunlight, temperature and chemical environment. The availability of soil mineral is an example of abiotic limiting factor. Growth of plant population depends on availability of soil minerals.
