The answer is vaporization, then condensation.
Here is a set of flash card that can help with this subject.
There are multiple uses of nuclear energy, one of which is these uses is (A) radioisotope used as tracers in industry<span>. A radioactive isotope is injected into the patient's area of interest, for example the bowel, and the movement of the radioactive isotope is tracked using the radiation it emits.</span>
Yes, your weight can change if the force of gravity is different on a different planet.
Like on the Moon because acceleration due to gravity is 1/6 that on the Earth, your weight on the Moon would be 1/6 the value on the Earth.
But note that you mass remains the same.
Answer: The lithosphere and the asthenosphere
Answer:
a. 78 degree
Explanation:
According to Snell's Law, we have:
(ni)(Sin θi) = (nr)(Sin θr)
where,
ni = Refractive index of medium on which light is incident
ni = Refractive index of ethyl alcohol = 1.361
nr = Refractive index of medium from which light is refracted
nr = Refractive index of ethyl alcohol = 1.333
θi = Angle of Incidence
θr = Angle of refraction
So, the Angle of Incidence is know as the Critical Angle (θc), when the refracted angle becomes 90°. This is the case of total internal reflection. That is:
θi = θc
when, θr = 90°
Therefore, Snell's Law becomes:
(1.361)(Sin θc) = (1.333)(Sin 90°)
Sin θc = 1.333/1.361
θc = Sin⁻¹ (0.9794)
θc = 78.35° = 78° (Approximately)
Therefore, correct answer will be:
a. <u>78 degree</u>
