Answer with explanation:

Complete question is provided in the attachment below.

There are 3 undefined term in geometry :1) A Point  2)  A line 3) A Plane.

When two lines are parallel they never meet , so the requirement to define them is lines and a plane on which they lie.

While when two lines are perpendicular , they intersect each other at a point by making a right angle between them.

So it required lines and a point to define it.

How many justified by Bohr model?
Dominik [7]

X-ray formation

Energy difference in the first ionization of the same group of elements

Differential linear emission spectra of different elements

Explanation:

The formation of x-ray, energy difference in the first ionization of the same group of elements and differential linear emission spectra of different elements can be justified by the Bohr model of the atom.

  • According to Neil Bohr, in an atom, the extranuclear part consists of electrons in specific spherical orbits around the nucleus.
  • Bohr's model explained the discrete lines in atomic spectrum of different elements.
  • Due to excitation of electrons, some rays are given off. Some of these are energetic like x-rays.
  • The energy difference between the first ionization of the same group of elements is a proof that electrons are in specific spherical orbits.
  • The higher the energy the level, the ease at which electrons can be removed and the lower the ionization energy.

What is the amplitude of oscillation a of the scale after the slices of ham land on the plate?
fgiga [73]

Answer:

0.093

Explanation:

A = √(mgh/K)

M= 0.7 h= 0.25

K= 200 g= 9.8

= √(0.7*9.8*0.25)/200

= √(1.715)/200

=√0.008575

A = 0.093m
