What is the de Broglie wavelength of a dust particle that has a mass of 1e-10 kg and a velocity of 0.05m/s?

From the question asked, we need to identify the key bits of information. Firstly, we are asked to find the de Broglie wavelength, so we write down the de Broglie relation: lambda = h/p In this equation we w...

A line L is parallel to y=4x+5 and passes through the point (-1, 6). Find the equation of the line L in the form y=ax+b . Find also the coordinates of its intersections with the axes.

Since L is parallel to y=4x+5 we know that the two lines have the same gradient. The gradient of a line in the form y=ax+b has is a, which means the gradient of y=4x+5 is 4, so L is y=4x+b and we just need t...
