The Mass of HD68988 Relative to Our Sun is 8.6 Times the Mass of the Sun

AI Thread Summary
The discussion centers on the mass of the star HD68988, which is calculated to be 2.31 x 10^30 kg. Participants clarify that to express this mass in terms of the Sun's mass, one must divide HD68988's mass by the Sun's mass. The Sun's mass is approximately 1.989 x 10^30 kg, making HD68988 about 8.6 times the mass of the Sun. The conversation highlights the importance of understanding how to convert mass measurements relative to a standard reference. Clear guidance is provided to help with the homework question.

Homework Statement


On October 15, 2001, a planet was discovered orbiting around the star HD68988. Its orbital distance was measured to be 10.5 million kilometers from the center of the star, and its orbital period was estimated at 6.3 days.

Question A:
What is the mass of HD68988? -- I found this: 2.31*10^{30} kg

Question B:
Express your answer in terms of our sun's mass. -- I have no idea what they mean by this.

Any ideas??

If your answer was 50 units and the sun's mass was 10 units, then your answer could be expressed as 5 sun masses. (Just divide.)

You'll need to look up the sun's mass.
 
Thanks for the help. I keep over thinking these problems and I need to stop.

Thread 'Voltmeter readings for this circuit with switches'
TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...
Thread 'Struggling to make relation between elastic force and height'
Hello guys this is what I tried so far. I used the UTS to calculate the force it needs when the rope tears. My idea was to make a relationship/ function that would give me the force depending on height. Yeah i couldnt find a way to solve it. I also thought about how I could use hooks law (how it was given to me in my script) with the thought of instead of having two part of a rope id have one singular rope from the middle to the top where I could find the difference in height. But the...
