Web3 Jul 2024 · Cosine is basically sine with a phase. phase of 180° will completely invert your signal. DC Offset adds a DC level to your sine wave signal e.g. 1V DC Offset means your sine wave will "oscillate" around 1V rather than 0V. Frequency is the number of cycles the sine wave will complete in a second. Tdelay adds delay before starting the source. Webu = tension in left rope. Equation 1: v ∗ c o s ( 60) − u ∗ c o s ( 45) = 0. Equation 2: v ∗ s i n ( 60) + u ∗ s i n ( 45) − 2500 k g = 0. Then, from Equation 1, solve for u: u = v ∗ c o s ( 60) c o s ( 45) And plug this in to Equation 2 … Web21 Oct 2024 · f = μN. Plug in the expression for normal force: f = μmg cos θ. Substitute this expression into the equation from the x-sum. (mg) x – f = ma x. (mg) x – μmg cos θ = ma x. Recall that (mg) x = mg sin θ (that was the whole point of this article). mg sin θ – μmg cos θ = ma x. Divide both sides of the equation by mass. buy moki headphones
