La respuesta correcta es 180 centímetros cúbicos o 180 
Explicación:
El primer paso para saber cuanto alcohol desaloja el prisma es calcular el volumen total del prisma. El volumen se puede encontrar usando la formula V (Volumen) = B (base) x h (altura). El proceso se muestra a continuación:
V = B x h
V = 36 
x 10 cm
V= 360
Finalmente, el volumen total del prisma debe dividirse en 2 considerando que solo la mitad del prisma fue sumergida y esta mitad equivale al volumen del alcohol desplazado.
360 ÷ 2 = 180
Answer:
Phase contrast microscope
Explanation:
It is used for viewing biological structures not visible under the microscope. It is used for viewing microrganisms live
Answer:
B) Yes, but only those electrons with energy greater than the potential difference established between the grid and the collector will reach the collector.
Explanation:
In the case when the collector would held at a negative voltage i.e. small with regard to grid So yes the accelerated electrons would be reach to the collecting plate as the kinetic energy would be more than the potential energy that because of negative potential
so according to the given situation, the option b is correct
And, the rest of the options are wrong
Answer:
Please check the attached file for the derivation
Explanation:
Check the attached file
n₂ = index of refraction of glass = 1.58
n₁ = index of refraction of air = 1
θ = Brewster's angle
Brewster's angle is that incident angle at which the the reflected light from the interface of two medium is completely polarized.
Brewster's angle is given as
θ = tan⁻¹(n₂ /n₁ )
θ = tan⁻¹(1.58/1 )
θ = 57.7 deg
hence the Brewster's angle comes out to be 57.7 deg
