Answer:
13.7m
Explanation:
Since there's no external force acting on the astronaut or the satellite, the momentum must be conserved before and after the push. Since both are at rest before, momentum is 0.
After the push
![m_av_a + m_sv_s = 0](https://tex.z-dn.net/?f=m_av_a%20%2B%20m_sv_s%20%3D%200)
Where
is the mass of the astronaut,
is the mass of the satellite,
is the speed of the satellite. We can calculate the speed
of the astronaut:
![v_a = \frac{-m_sv_s}{m_a} = \frac{-1200*0.14}{92} = -1.83 m/s](https://tex.z-dn.net/?f=v_a%20%3D%20%5Cfrac%7B-m_sv_s%7D%7Bm_a%7D%20%3D%20%5Cfrac%7B-1200%2A0.14%7D%7B92%7D%20%3D%20-1.83%20m%2Fs)
So the astronaut has a opposite direction with the satellite motion, which is further away from the shuttle. Since it takes 7.5 s for the astronaut to make contact with the shuttle, the distance would be
d = vt = 1.83 * 7.5 = 13.7 m
Ok, SO my family runs a Dog Day Care. ( littlecanineclubhouse.com if you need proof.)
And what i have found it that it really depends on the type of dog it is.
Such as a PUG, they can live anywhere between 15 to 20 years.
A Boston Bull Terrier can live up to about 10 to 15 years.
A French Bull dog can live anywhere up to 10 to 12 years.
A golden Retriever can live up to 10 to 12 years.
ETC.
SO it really depends on the dog.
The direction of its displacement wil be
c.northeast
In fact, the dog walks north for 10 meters and east for another 10 meters. The path of the dog can be represented with two vectors, A pointing north (of magnitude 10 meters) and B pointing east (of magnitude 10 meters). The direction of the resultant vector (due to east) will be given by
![tan \theta =\frac{A}{B}=\frac{10}{10}=1](https://tex.z-dn.net/?f=%20tan%20%5Ctheta%20%3D%5Cfrac%7BA%7D%7BB%7D%3D%5Cfrac%7B10%7D%7B10%7D%3D1%20)
![\theta=tan^{-1} (1)=45^{\circ}](https://tex.z-dn.net/?f=%20%5Ctheta%3Dtan%5E%7B-1%7D%20%281%29%3D45%5E%7B%5Ccirc%7D%20)
and the direction will be north-east.
Answer:
An atom with a closed shell of valence electrons (corresponding to an electron configuration s2p6) tends to be chemically inert. An atom with one or two valence electrons more than a closed shell is highly reactive, because the extra valence electrons are easily removed to form a positive ion.Explanation:
