The relationship between velocity, frequency and wavelength is given by: v=fλ. In this case, we have: v=fλ1 and v=2fλ2 .Since the question states that the velocity is const...
To answer this question you need to write down and solve an equation. Let's call t a tin of soup and p, a packet. We have: 5t=1750 and 4t+3p=1490. We want to know how much is 3t+2p. 1. Isolate t to find v...
Theoretical Yield of NaCl = 86.7kg (3sf)Percentage Yield of Iron = 57.7% (3sf)
Using the chain rule:If the parameter used is 't', differentiate each equation with respect to 't' so that you have answers for dy/dt, and dx/dt.From the chain rule it is known that: "dy/dx=dy/du * d...
first expand the brackets (3x-2)(x+1) to get 3x2-2x+3x-2, then we can simplify this to get 3x2+x-2.Then multiply this by x to get the final answer: 3x3+x2-2x.
