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
Answer:
A
Explanation:
the best choose is A..........
Answer:
c) 89.55 cm/s
Explanation:
in this situation you have to divide to find the speed-
120/1.34 = 89.55223880...
closest answer is c
or rounded
89.55
hope this helps.
1.- Description In science, a common, vulgar, vernacular, trivial, or popular name is any name by which a species or other concept is known, and which is not the scientific name.
2.-a principal taxonomic category that ranks above class and below kingdom
3.-biology, taxonomy) A scientific name at the rank of species, with two terms: the generic name (generic epithet, the genus of the species) and the specific name (a term used only in zoology, never in botany, for the second part of a binomial) or the specific epithet (the term always used in botany, which can also be used in zoology).
