What type of wave shows wave-particle duality? Mechanical or Electromagnetic?

2 answers:

5 0

I would have have said electromagnetic. This is because visible light can have a calculable wavelength and frequency and can undergo diffraction patters as a wave, and yet can also be modelled as a particle called a photon which is used when describing how electrons jump between energy levels as it is a discrete packet of energy. It is not mechanical as they require a medium to travel through.

If an object doubles in mass, what happens to its inertia?

son4ous [18]

Inertia is proportional to mass. It is a measure of the resistance to changes in velocity. Inertia is a property of mass and cannot change. Momentum changes as an object changes its velocity.

HENCE The inertia will also be doubled

Can someone explain it with steps?

Anton [14]

Answer:

Option C is the correct answer

Explanation:

Distance travelled by car during reaction time

$=15\times0.4\\\\=6m$

The car stopped before hitting the animal by $1 m$

Distance travelled during deceleration is $21-6-1=14m$

Hence by $v^2=u^2+2as$

We have

$0^2=15^2+2 \cdot a \cdot 14\\\\a=\frac{-225}{28} \\\\=-8.03m/s^2$

Option C is the correct answer

What is the condition for an object experiencing free fall?

S_A_V [24]

Answer:

The body acts under the influence of gravity.

Explanation:

An object experiencing free fall is acting under the influence of gravitational force and the acceleration due gravity is positive for any falling object. The body is able to fall freely due to the effect of gravity on it. This gravity effect causes the body to get attracted to the earth's gravitational surface due to gravitational pull exerted on the body.
