you are given an unknown liquid and asked to help identify it by finding its index of refraction. you shine a laser beam so that

it first passes through glass and then through the liquid. the light crosses the interface from the glass with 1.60 refractive index to the liquid at an incident angle of 40 . the refracted angle of the light in the liquid is 55 . what is the refractive index of the liquid

Answer:

Explanation:

The refractive index of liquid with respect to glass =  sin of Angle of incidence in glass / (sin of angle of refraction in liquid )

The refractive index of liquid with respect to glass = sin 40 / sin 55

refractive index of liquid / refractive index of glass = sin 40 / sin 55

refractive index of liquid / 1.60 = sin 40 / sin 55

refractive index of liquid = 1.6 x sin40 / sin 55

= 1.6 x .642 / .819

= 1.254 .

An object with a mass of 70 kilograms is supported at a height 8 meters above the ground. What's the potential energy of the obj
Fofino [41]
The potential energy of an object is defined as the energy it harnesses as a result of the downwards pull of gravity. The acceleration due to gravity is equivalent to 9.8 m/s^2. Potential energy can be calculated using the formula: PE = mgz

where:
m = mass
g = acceleration due to gravity
z = height

Therefore, for this problem, the PE = 70(9.8)(8) = 5488 Joules

devlian [24]

Answer:

The correct answer is Cognitive.

Explanation:

The psychologist Leon Festinger proposed the theory of cognitive dissonance, which explains how people try to maintain their internal consistency. He suggested that individuals have a strong inner need that pushes them to ensure that their beliefs, attitudes and behavior are consistent with each other. When there is inconsistency between them, the conflict leads to a lack of harmony, something that people strive to avoid.

This theory has been widely studied in the field of psychology and can be defined as the discomfort, tension or anxiety that individuals experience when their beliefs or attitudes conflict with what they do. This displeasure can lead to an attempt to change behavior or defend their beliefs or attitudes (even reaching self-deception) to reduce the discomfort they produce.
