The Average Speed of the orbiting space shuttle is

Chemistry

maxonik [38]3 years ago
8 0

Explanation:

It is given that, the Average Speed of the orbiting space shuttle is  17500 miles/hour.

We need to convert the speed in kilometers/ second

We know that,

1 mile = 1.609 km

or

1 km = 0.621 miles

1 hour = 3600 seconds

17500\ \dfrac{\text{miles}}{\text{hour}}=17500\ \dfrac{\text{miles}}{\text{h}}\times \dfrac{1\ h}{3600\ s}\\\\=17500\times \dfrac{\text{miles}}{3600\ s}

Now cancel the miles in numerator.

17500\times \dfrac{\text{miles}}{3600\ s}=17500\times \dfrac{\text{miles}}{3600\ s}\times \dfrac{1.609\ km}{1\ \text{miles}}\\\\=17500\times \dfrac{1.609}{3600}\ km/s\\\\=7.82\ km/s

So, 17500 miles/hour is equal to 7.82 km/s.

<h3><u>Answer;</u></h3>

3p34s23d7

<h3><u>Explanation</u>;</h3>
  • Electrons in an atom are contained in specific energy levels that are different distances from the nucleus.
  • Within each energy level is a volume of space where specific electrons are likely to be located, called orbitals. Orbitals are of different shapes, denoted by a letter (s, p, d, f, g).
  • S-orbital takes a maximum of two electrons, p-orbital take a maximum of six electrons, d-orbital takes a maximum of 10 electrons, and so fourth.
  • The electron filling pattern takes; 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p.........
  • Therefore; in this case after 3p3, we then go to 4s, with 2 electrons, then 3d which takes 7 electrons.

In an estuary, _____.
lapo4ka [179]

B; Seawater mixes with freshwater so the water has intermediate salinity

Explanation:

In an estuary, seawater mixes with freshwater so the water has intermediate salinity. Estuaries are usually located in transitional environments.

  • Estuary is the wide part of a river where it nears the sea.
  • This is called a transitional zone.
  • Water from continental rivers usually fresh are brought in close contact with ocean water that is salty.
  • The water here is said to be brackish as it is intermediate between salt and seawater.
  • Organisms living in such terrain must be be well adapted to changing salinity.
