The statement given in the question is FALSE.
Ecological Succession refers to the change in the specie structure of an ecosystem over a long period of time. There are two types of succession, primary and secondary succession. A primary success is said to occur when an ecosystem is totally destroyed to the extent that even the soil is wipe out. In this case, the ecosystem development has to start from the scratch. A succession is said to secondary if only part of the ecosystem is destroyed.
Answer:we know,
displacement = 100 meters
time = ?
average velocity = 10.8 m/s
now,
average velocity = displacement ÷ time
or, 10.8 = 100 ÷ time
or, 10.8 × time = 100
or, time = 100 ÷ 10.8
Time = 9.25 seconds
Answer:
It would not be safe to walk out to where waves are breaking due to the effect of rip currents
Explanation:
The water depth in the surf zone is between 5 to 10 meters deep and with a wavelength of 30 meters, the speed of the wave is considerably fast such that control for safety may be difficult
Also the speed of the wave is directly related to the depth of the water which means that where the wave described above is fast as well as the rip current, also the water depth is expected to be considerable for a non swimmer
It is best to seek for sign post regarding safe areas and do not go into the water where there are no lifeguards or marked safe zones.
