Hobbes argues that in a ‘state of nature’, individuals are not subject to a common higher authority; instead they are free to follow their desires and act upon their own private judgement. We all have a n...

Amplitude of a periodic function is the maximum height it reaches above the centre line (or the lowest). This expressed in the equation as '3'. If the 3 was not there, then the sin wave would have an ampl...

λ=h/p λ=h/mv λ= 6.6310^-34/0.130 λ= 2.21*10^-34m We cannot see the rock's de broglie wave because its wavelength is much smaller than that of the visible spectrum

Start with Newton's Law of Gravitation: F=(GMm)/R^2 (1) Since orbits are assumed to be circular recall the equation for centripetal force: F=(mv^2)/R (2) We can now equate these 2 forces due to them being...

The acceleration or unbalanced force is proportional to the displacement of the object from its equilibrium position and acts in the opposite direction

Mathematically, this may be expressed as a=-...
