Which are characteristics of a gas? (Select all that apply.)It cannot move.It fills the container it is in.It can be compressed.
Aleonysh [2.5K]

Answer:  no definite shape (takes the shape of its container)

no definite volume.

particles move in random motion with little or no attraction to each other.

highly compressible.

Explanation:

Gases have three characteristic properties: (1) they are easy to compress, (2) they expand to fill their containers, and (3) they occupy far more space than the liquids or solids from which they form.

Two satellites are in circular orbits around a planet that has radius 9.00×106 m. One satellite has mass 68.0 kg, orbital radius
olasank [31]

Answer:

v₂ = 5131.42 m/s

Explanation:

given,

radius of the planet = r₁ = 9.00×10⁶ m

mass of the satellite = m₁ = 68 Kg

orbital radius = r₁ = 8 x 10⁷ m

orbital speed = v₁ = 4800 m/s

mass of second satellite = m₂ =  84.0 kg

orbital radius = r₂ = 7.00×10⁷ m

orbital speed of second satellite = v₂ = ?

using orbital speed of satellite

            v = \sqrt{\dfrac{GM}{r}}

     so,

            v \alpha \dfrac{1}{\sqrt{r}}

now,

            \dfrac{v_1}{v_2} =\sqrt{\dfrac{r_2}{r_1}}

            \dfrac{v_2}{4800} =\sqrt{\dfrac{8\times 10^7}{7 \times 10^7}}

                v₂ = 5131.42 m/s

The orbital speed of second satellite is equal to v₂ = 5131.42 m/s
