Suppose that each component of a certain vector is doubled. (a) by what multiplicative factor does the magnitude of the vector c
gladu [14]
<span>a. The magnitude of the vector is doubled as well. Let's say we have a 2-dimensional vector with components x and y. It's magnitude lâ‚ is given by: lâ‚ = âš(x² + y²) If we double the components x and y, the new magnitude lâ‚‚ is: lâ‚‚ = âš((2x)² + (2y²)) With a bit of algebra... lâ‚‚ = âš(4x² + 4y²) lâ‚‚ = âš4(x² + y²) lâ‚‚ = 2âš(x² + y²) We can write the new magnitude lâ‚‚ in terms of the old magnitude lâ‚. lâ‚‚ = 2lâ‚ Therefore, the new magnitude is double the old one. It should be clear that this relationship applies to 3D (and 1D) vectors as well. b. The direction angle is unchanged. The direction angle θ₠for a 2-dimensional vector is given by: θ₠= arctan(y / x) If we double both components, we get: θ₂ = arctan(2y / 2x) θ₂ = arctan(y / x) θ₂ = θ₠The new direction angle is the same as the old one.</span>

Which solution will have more gas dissolved in it, A solution under high-pressure or one under low pressure?
gayaneshka [121]
High pressure, because the more pressure, the less volume, so the atoms have to get closer together.
