Homework Statement



I'd like to know if I am on the right track. I'm not sure if I am doing this right...

Find the angular velocity, in rad/s, of the Earth due to its daily spin on its axis, the Earth due to its yearly motion around the sun, and our moon due to its monthly motion around the earth.

You are doing it correctly. The two parts you have done are right.
And a quick couple google searches reveals your approximate answers to be very close indeed to the real values.
 
yayy. thanks your right i got them all correct... just trying to double check my work before I enter it into masteringphysics since they take off ridiculous amounts of points. etc etc. thanks
 
Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
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 'Trying to understand the logic behind adding vectors with an angle between them'
My initial calculation was to subtract V1 from V2 to show that from the perspective of the second aircraft the first one is -300km/h. So i checked with ChatGPT and it said I cant just subtract them because I have an angle between them. So I dont understand the reasoning of it. Like why should a velocity be dependent on an angle? I was thinking about how it would look like if the planes where parallel to each other, and then how it look like if one is turning away and I dont see it. Since...
