Answer:
Answer: Kelvin ________________
Answer:
true about microscopic particle is that they can explain the phenomena of diffraction and interference.
Explanation
the first thing mentioned in question particles are localized in space according to classical physics particle can be well localized in space because its momentum and position can be determine simultaneously .second their properties can be measured and they can act like wave particle by particle build up a wave. so all of they things mention above only thing true about particles is that they describe the phenomena of diffraction and interference.
Explanation:
It is given that,
Wavelength of x-rays = 2 nm
Plane spacing, d = 0.281 nm
It is assumed to find the scattering angle for second order maxima.
For 2nd order, Bragg's law is given by :

For second order, n = 2

Here, θ is not defined. Also, the wavelength of x-rays is more than the plane spacing. It means that it cannot produce any diffraction maximum.
Answer:
0.2 m/s
Explanation:
= Mass of glider A= 0.125 kg
= Mass of glider B = 0.375 kg
= Initial Velocity of glider A = 0 m/s
= Initial Velocity of glider B = 0 m/s
= Final Velocity of glider A = 0.6 m/s
= Final Velocity of glider B
As linear momentum is conserved

Magnitude of the glider B at this time is 0.2 m/s
Answer:
The Geomagnetic North Pole, a related point, is the pole of an ideal dipole model of the Earth's magnetic field that most closely fits the Earth's actual magnetic field. The North Magnetic Pole moves over time according to magnetic changes and flux lobe elongation in the Earth's outer core.
