Answer:
A = 2,8333 s
Explanation:
El periodo es definido como el tiene que toma de dar una oscilación.
En este caso realiza varias osicilacion por lo cual debemos encontrar el promedio del perdono.
T = t/n
calculemos
A = 34,0/ 12,0
A = 2,8333 s
Answer:
g = 0.85 m![s^{-2}](https://tex.z-dn.net/?f=s%5E%7B-2%7D)
Explanation:
g = ![\frac{GM}{h^{2} }](https://tex.z-dn.net/?f=%5Cfrac%7BGM%7D%7Bh%5E%7B2%7D%20%7D)
were; g is the acceleration due to Earth's gravity, G is Newton's gravitation constant (6.674 x
N![m^{2}](https://tex.z-dn.net/?f=m%5E%7B2%7D)
), M is the mass of the earth (5.972 x
kg), and h is the distance of meteoroid to the earth.
h = 3.40 x R
= 3.40 x 6371 km
h = 21661.4 km
= 21661400 m
Thus,
g = ![\frac{6.674*10^{-11}*5.972*10^{24} }{(21661400)^{2} }](https://tex.z-dn.net/?f=%5Cfrac%7B6.674%2A10%5E%7B-11%7D%2A5.972%2A10%5E%7B24%7D%20%20%7D%7B%2821661400%29%5E%7B2%7D%20%7D)
= ![\frac{3.9857 *10^{14} }{4.6922*10^{14} }](https://tex.z-dn.net/?f=%5Cfrac%7B3.9857%20%2A10%5E%7B14%7D%20%7D%7B4.6922%2A10%5E%7B14%7D%20%7D)
= 0.84944
g = 0.85 m![s^{-2}](https://tex.z-dn.net/?f=s%5E%7B-2%7D)
The acceleration due to the Earth's gravitation is 0.85 m

Question: Predicting the shape of a molecule is relatively straight forward. A molecule's shape will always be determined by the number of electron pairs around the central atom. The number of electron pair corresponds to the number of atoms that are bound to the central atom of the molecule. For example, water contains two hydrogen atom bound to one atom of oxygen, giving the molecule a linear geometry.
Suppose that the model presented by student 1 is correct. Based on the information provided, what would be the bond angle in a molecule of perchlorate ion.
Answer: Suppose that the model presented by student 1 is correct The (perchlorate ion) will be a tetrahedral shape, O-Cl-O bond angle 109.5 due to four groups of bonding electrons and no lone pairs of electrons.

What is wavelength ?
The distance over which a periodic wave's shape repeats is known as the wavelength in physics. It is a property of both traveling waves and standing waves as well as other spatial wave patterns. It is the distance between two successive corresponding locations of the same phase on the wave, such as two nearby crests, troughs, or zero crossings. The spatial frequency is the reciprocal of wavelength. The Greek letter lambda () is frequently used to represent wavelength. The term wavelength is also occasionally used to refer to modulated waves, their sinusoidal envelopes, or waves created by the interference of several sinusoids.
