Answer:
c) Anti-top
Explanation:
Protons are particles which belong to the hadron group of particles. The antimatter equivalent particle is antiproton
Electrons are particles that belong to the fermion group of particles. The antimatter equivalent is antielectron
Antitop quarks are particles that belong to the group family of particles. They are the antimatter equivalent of top quarks.
Gluons are particles that belong to the group of particles called bosons.
Tau neutrinos are particles that belong to the fermion group of particles. The antimatter equivalent is Tau antineutrino.
Answer:
displacement is a vector quantity
Answer:
35.36776 Hz
Explanation:
B = Magnetic field = 
= Maximum voltage = 20 V
d = Diameter of coil = 40 cm = 0.4 m
A = Area = 
N = Number of turns = 500
= Angular velocity
Maximum emf is given by
The angular velocity would be 35.36776 Hz
Absorption:
<span>If the wavelength of the light happens to match the distance between two electron levels in the material, it can be absorbed. Light disappears and its energy becomes part of the heat energy of the material. </span>
<span>Metals have so many free electrons that all wavelengths are absorbed -- they are opaque to xrays, visible light, radio waves, everything. </span>
<span>Pigments have specific electron gaps that absorb only the light of a specific wavelength, which we see as color </span>
<span>Transparent materials do not happen to have any gaps between electron levels that match any of the wavelengths of visible light. </span>
