Answer:
8.800s
Explanation:
When the performer swings, she oscillates in SHM about Lo of the string with time period To = 8.90s.
First, determine the original length Lo, where for a SHM the time period is related to length and the gravitational acceleration by the equation
T = 2π×√(Lo/g)..... (1)
Let's make Lo the subject of the formulae
Lo = gTo^2/4π^2 ..... (2)
Let's put our values into equation (2) to get Lo
Lo = gTo^2/4π^2
= (9.8m/s^2)(8.90s)^2
------------------------------
4π^2
= 19.663m
Second instant, when she rise by 44.0cm, so the length Lo will be reduced by 44.0cm and the final length will be
L = Lo - (0.44m)
= 19.663m - 0.44m
= 19.223m
Now let use the value of L into equation (1) to get the period T after raising
T = 2π×√(L/g)
= 2π×√(19.223m/9.8m/s^2)
= 8.800s
Limiting factors are what controls the population of an ecosystem. It also limits the kind of organisms that inhabit it. Limiting factors can be abiotic or biotic. Abiotic factors are the nonliving factors that affect the living ones. From the given options above, the only biotic limiting factor is vegetation. The correct answer would be option B.
Answer:
it is important to view cells under a microscope because cells can change?
False
Explanation:
Cell does not change when viewing under microscope, it is expedient to view under microscope because it is a microorganism that can not be seen with naked rather than with a microscope
