Balanced field takeoff
Describe the process of balanced field takeoff in brief?
Expert
The ‘balanced field’ with respect to aircraft takeoff performance signifies to the minimum length of runway which will permit for an aircraft to accelerate to V-1 (that is, decision speed), experience failure of the vital engine, and then either stop in the remaining run-way or continue to a successful takeoff meeting all the applicable takeoff performance criteria.
Give one benefit of a scanning electron microscope over the transmission electron microscope? Briefly explain it.
What do you mean by communication? Illustrate in brief.
Pfund series: The series that explains the emission spectrum of hydrogen whenever the electron is jumping to the fifth orbital. Each line is in the infrared part of the spectrum.
What do you mean by the term crest? Briefly illustrate it.
Brownian motion - The continuous random motion of a solid microscopic particle whenever suspended in a fluid medium due to the effect of ongoing bombardment by molecules and atoms.
Gray: Gy (after L.H. Gray, 1905-1965): The derived SI unit of engrossed dose, stated as the absorbed dose in which the energy per unit mass communicated to the matter by the ionizing radiation is 1 J/kg; it therefore has units of J/kg
Balmer series (J. Balmer; 1885): An equation that explains the emission spectrum of hydrogen whenever an electron is jumping to the next orbital; four of the lines are in visible spectrum, and the remainder (residue) are in the ultraviolet.
The voltage v mV in a circuit is given by: v = 20 sin (200 Πt - 0.7854) where t is the time in seconds (a) State the amplitude, frequency, period and phase angle of v.(b) Determine the initial voltage.(c) Determin
Lumen: lm: The derived SI unit of luminous flux, stated as the luminous flux produced by a uniform point source of 1 cd releasing its luminous energy over a solid angle of 1 sr; it therefore has units of cd sr.
