Heisenberg's uncertainty principle tells us that heisenberg's uncertainty principle tells us that the de broglie wavelength of an electron is related to its velocity the more accurately we know the position of a particle, the less accurately we can know the velocity of that particle an electron is actually something intermediate between a particle and a wave complementary properties are those properties that can be measured simultaneously

The more accurately we know the position of a particle, the less accurately we can know the velocity of that particle.

Explanation:

Heisenberg's uncertainty principle tells us that:

The De Broglie wavelength of an electron is related to its velocity. NO. This is true according to the following expression.

c = λ . v

where,

c: speed of light

λ: wavelength

v: frequency

But this is not Heisenberg's uncertainty principle.

The more accurately we know the position of a particle, the less accurately we can know the velocity of that particle. YES. The corresponding mathematical expression is:

Δv . Δx = h / 4πm

where,

Δv: uncertainty in the velocity

Δx: uncertainty in the position

h: Planck's constant

m: mass

An electron is actually something intermediate between a particle and a wave. NO. This is known as wave-particle duality.Complementary properties are those properties that can be measured simultaneously. NO. The complementary properties can be defined as those properties which cannot be simultaneously measured and observed.

The density of water is 1 g/cm cubed and in order for the pebble to sink its density has to be greater than the density of water and in order for the twig to float its density has to be less than the density of water

The question is incomplete. complete question is attached belowanswer: correct answer is option b  i.e.  solid particles  reason: filter paper has small pores, through which smaller particles can pass through. however, solid particles  have relatively larger size. hence, they are least likely to pass through.
