Components and Vectors and Lengths, Oh My

AI Thread Summary
The discussion focuses on calculating the components and length of a vector resulting from the sum of two given vectors, V1 and V2. The components of the resultant vector are identified as Vx = 8.5, Vy = -3.6, and Vz = 14. The user expresses confusion about the length calculation, initially using the formula (Vx)² + (Vy)² + (Vz)² = √Length but receives an error from their program. They acknowledge a misunderstanding regarding the squaring of negative values. The conversation highlights the importance of correctly applying vector addition and length formulas in physics.

Hey guys! I am back for a second time. (Woo) More Awesome Physics underway!

Homework Statement



The components of a vector V are often written (Vx, Vy, Vz). What are the components and length of a vector which is the sum of the two vectors, V1 and V2, whose components are (3.4, 1.0, 15.0) and (5.1, -4.6, -1.0)?



Homework Equations



(Vx)=8.5
(Vy)=-3.6
(Vz)=14


The Attempt at a Solution


To my understanding it should be (Vx)² + (Vy)² + (Vz)² = √Length

But my Program say nay to such an answer...Is there somthing I missed?

Thread 'Rolling without slipping on a curved surface'

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...
