Friction and gravity (both a function of weight and structure) will always stop an object. Assuming it’s a smooth ball those would be the two primary slowing components assuming no outside force such as like a bat hitting it :)
The two properties of the ink components that determine their movement along the chromatography paper/fabric are:
the solubility of ink constituent in chemical solvent.
the mixture of colour constituents in the ink.
Explanation:
Chromatography is the process in which the chemicals of the mixture are separated on the basis of constituents.
Capillary action let the colors of ink separate into their constituents. When ink is subjected to solvents it gets dissolve and gets separated.
The property of ink that led to determine their movement is:
Ink is made of many dyes of different colours, pigments etc.
The chemicals that has the best solubility in the chemical will move up on the chromatography paper and fabric.
The order of decreasing energy is ultraviolet rays, infrared rays, and microwaves.
Frequency is defined as the number of occurrences of the event. In wave function, frequency is the number of times the given waveform passes through a given point. The SI unit of frequency is Hertz.
Photons are particles that do not contain mass but possess energy. Photon energy is calculated by the formula Planck's constant h ( 6.63✖10-34 J/s) multiplied by the frequency. Hence frequency is directly proportional to the energy of the photon.
Higher frequency waves will have higher energy. Lower frequency waves will have lower energy.

Rank the following photons in terms of decreasing energy:
(a) IR (v = 6.5 x 10¹³ s⁻¹)
(b) microwave (v = 9.8 x 10¹¹ s⁻¹)
(c) UV (v = 8.0 x 10¹⁵ s⁻¹)
Answer: 4.99×10²³ photons
Explanation: The energy of a photon is given as
E= hf
h= Planck constant = 6.626×10^-34Js
f= frequency = c/x
C= speed of light = 3×10^8 m/s
x= wavelength= 525nm= 525×10^-9
E= hc/x
E= 6.626×10^-34 × 3×10^8 m/s /( 525×10^-9)
E= 3.79×10^−19 J/ Photon
E= 3.79×10^−22KJ/Photon
189KJ/3.79×10^−22KJ/photon=
4.99×10²³photons.
Therefore the number of photons is
4.99×10²³photons.
Answer:
Equilibrium will lie to the right.
Explanation:
That means HF is stronger acid than .
Alternatively, it can be said that is a stronger base than .
Therefore HF readily gives proton to to form and than the reverse reaction.
So, the equilibrium will lie more towards the right i.e. towards formation of and .
