A satellite in a circular orbit 1250 kilometers above Earth makes one complete revolution every 110 minutes. What is its linear
Ivenika [448]

Answer:

\large \boxed{\text{approximately 435.7 km/min}}  

Step-by-step explanation:

1. Angular speed

The angular speed ω is the angle θ swept out by the satellite in a given time t.

\omega = \dfrac{\theta}{t} = \dfrac{2\pi}{\text{110 min}}

2. Linear speed

The formula for the linear speed v is

v = rω, where

r = the distance from the centre of the Earth = 6378 km + 1250 km = 7628 km

\begin{array}{rcl}v & = & r\omega\\& = & \text{7268 km} \times \dfrac{2\pi}{\text{110 min}}\\\\& \approx & \textbf{435.7 km/min}\\\end{array}\\\text{The linear speed of the satellite is $\large \boxed{\textbf{approximately 435.7 km/min}}$}

Step-by-step explanation:

coordinate point of B(2,5)

and coordinate point ofC(3,1)

Distance of BC

\sqrt{ {(x2 - x1)}^{2} +  {(y2 - y1)}^{2}  }

=  \sqrt{ {(3 - 2)}^{2}  +  {(1 - 5)}^{2} }

=  \sqrt{ {1}^{2} +  {( - 4)}^{2}  }

=  \sqrt{1 + 16}  =  \sqrt{17}  = 4.12 = 4.1
