The train stopped just a few inches before the handcar. The driver got out and harnessed the handcar to the engine and slowly started moving towards the station. The boys felt relaxed.
If the block is in equilibrium, then the net force acting on it is zero.
We have therefore to resolve each force along the x- and y- direction, and equate the net force along each direction to zero. Doing so, we obtain the following equations:
[tex]T_B cos 45^{\circ} - T_A sin 60^{\circ} = 0\\T_B sin 45^{\circ} - T_A cos 60^{\circ} - W = 0[/tex]
And substituting into the second equation, we find the tension in cord A:
[tex](T_A \frac{sin 60^{\circ}}{cos 45^{\circ}}) sin 45^{\circ} - T_A cos 60^{\circ} - W = 0\\T_A (sin 60^{\circ} tan 45^{\circ} - cos 60^{\circ}) = W\\T_A=\frac{W}{ (sin 60^{\circ} tan 45^{\circ} - cos 60^{\circ})}=683 N[/tex]
3. The ink in the suspect's pen separated into the same number of pigments as the ink in the note.
4. Changed
5. Separated
6. I would believe that a colored ink is a mixture if I see different colors.
7. Students would all get 100% on every lab! the lab walkthrough Chemistry Problems and Solutions Manual
8. Re-write the answer exactly as written in the walkthrough. That way, there's no chance that you'll mess it up and you're guaranteed to get full points for it.
9. The answers to the questions in the lab reports are almost always in the walkthrough and I want you to use those answers!
10. Put a slip of paper in a jar of alcohol and see if the fabric dye separates into different pigments.

Explanation:
If the block is in equilibrium, then the net force acting on it is zero.
We have therefore to resolve each force along the x- and y- direction, and equate the net force along each direction to zero. Doing so, we obtain the following equations:
[tex]T_B cos 45^{\circ} - T_A sin 60^{\circ} = 0\\T_B sin 45^{\circ} - T_A cos 60^{\circ} - W = 0[/tex]
where
[tex]T_A[/tex] is the tension in cord A
[tex]T_B[/tex] is the tension in cord B
W = 250 N is the weight of the block
From the first equation we get:
[tex]T_B = T_A \frac{sin 60^{\circ}}{cos 45^{\circ}}[/tex]
And substituting into the second equation, we find the tension in cord A:
[tex](T_A \frac{sin 60^{\circ}}{cos 45^{\circ}}) sin 45^{\circ} - T_A cos 60^{\circ} - W = 0\\T_A (sin 60^{\circ} tan 45^{\circ} - cos 60^{\circ}) = W\\T_A=\frac{W}{ (sin 60^{\circ} tan 45^{\circ} - cos 60^{\circ})}=683 N[/tex]
