A binary star system consists of two stars of masses m1 and m2. The stars, which gravitationally attract each other, revolve aro

Answer: $a_{2}=\frac{m_{1}}{m_{2}} a_{1}$

Explanation:

The rest of the question is below:

Find a2, the magnitude of the centripetal acceleration of the star with mass m2.

Assuming both stars are describing a uniform circular motion, their acceleration vector is directed towards the center of mass of the system (that's why it's called centripetal acceleration).

Now, according to Newton's 2nd law, the force $F$ is directly proportional and in the same direction as the acceleration.

For $m_{1}$ :

$F_{1}=m_{1}a_{1}$

For $m_{2}$ :

$F_{2}=m_{2}a_{2}$

If the centripetal force is the same for both stars:

$F_{1}=F_{2}$

$m_{1}a_{1}=m_{2}a_{2}$

Isolating $a_{2}$ :

$a_{2}=\frac{m_{1}}{m_{2}} a_{1}$

What is the main wiring plan for houses to ensure that each receptacle and light socket is the same voltage?

sergij07 [2.7K]

Every outlet, receptacle, lamp, appliance, and other directly wired device in the house must all be connected in parallel.

-- This ensures that each receptacle and light socket is supplied the same voltage.

-- It also ensures that turning off or unplugging one device won't cut off the power to a bunch of others in the house.
