AI Thread Summary
To calculate the vector components of A and B in different coordinate systems, trigonometric functions such as sine and cosine are essential. For vector A, the x component is 0 and the y component is -3.5 m in system 1. The discussion highlights difficulty in determining the x and y components of vector B in system 1, as well as both vectors in system 2. Understanding the angles and applying the correct trigonometric formulas is crucial for solving these components. Mastering these calculations is necessary for accurate vector analysis in physics.

Homework Statement


Let A= (3.5 m, vertically downward) and B = (4.1 m, 120° clockwise from ). Find the x and y components of and in each of the two coordinate systems shown in Figure Ex3.21. (attached)


Homework Equations





The Attempt at a Solution



I already have 0 for the x component of A for system 1 and -3.5 for the y component of of A for system one...I can't figure out the B x and y for system 1 . I can't find the A x&y and B x&y for system 2 help!

You'll need to use trigonometry (sin and cos) to find the x and y components of the vectors.

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 'Correct statement about a reservoir with an outlet pipe'

The answer to this question is statements (ii) and (iv) are correct. (i) This is FALSE because the speed of water in the tap is greater than speed at the water surface (ii) I don't even understand this statement. What does the "seal" part have to do with water flowing out? Won't the water still flow out through the tap until the tank is empty whether the reservoir is sealed or not? (iii) In my opinion, this statement would be correct. Increasing the gravitational potential energy of the...
