# Identifying third-law pairs in two masses connected by a string
Consider two masses connected by a string over a pulley, like so:
Where mass $$M$$ is held in place by a hand.
I'm asked to draw free-body diagrams for mass $$m$$ and $$M$$ individually, and identify third-law pairs in the two diagrams. I'm then asked... | {} |
# 9: Systems of Equations and Inequalities
In this chapter, we will investigate matrices and their inverses, and various ways to use matrices to solve systems of equations. First, however, we will study systems of equations on their own: linear and nonlinear, and then partial fractions.

Yes, in case of VeraCrypt there is a difference, but it is negligible in practice. First we need to consider how VeraCrypt actually performs the cascading of the encryption algorithms which is (literally) a block-wise chaining. E.g.: $$C=E_{XTS}^{1}(E_{XTS}^{2}(E_{XTS}^{3}(M)))$$ where each $E$ is a bloc... | {} |

# Calculate pH of a buffer solution
Calculate the pH in a buffer prepared from $$\pu{50 mL, 0.30 M}$$ formic acid ($$\ce{HCOOH}$$) and $$\pu{30 mL, 0.40 M}$$ sodium formate ($$\ce{HCOONa}$$).
My way of solving:
$$n_{\ce{HCOOH}} = 0.05 \times 0.3 = \pu{0.015 mol}$$
$$n_{\ce{HCOONa}} = 0.03 \times 0.4 = \pu{0.012 mol... | {} |
