Microwaves and radio waves are both used for communication purposes. Microwaves have a higher frequency, and therefore a smaller wavelength. Because of this, microwaves can travel through the Earth's atmo...

K=0.5mv^2 K=0.50.03*(45^2) K=30.4J

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=-...
