La rapidez es una magnitud escalar que relaciona la distancia recorrida con el tiempo.
La velocidad es una magnitud vectorial que relaciona el cambio de posición (o desplazamiento) con el tiempo.
Copernicus started a scientific revolution with his theory that, D the Earth revolved around the sun.
Answer:
The thickness of the oil film is 198 nm.
Explanation:
Given that,
Refractive index of glass plate = 1.60
Refractive index of oil = 1.29
Wavelength = 511 nm
We need to calculate the thickness of the oil film
Using formula of path difference
Where, n = refractive index
t = thickness
= wavelength
Put the value into the formula
Hence, The thickness of the oil film is 198 nm.
Answer:
The thyroid gland produces thyroxine (referred to as T4), which is a relatively inactive prohormone. The highly active hormone is triiodothyronine (referred to as T3).
Key actions of adrenaline include increasing the heart rate, increasing blood pressure, expanding the air passages of the lungs, enlarging the pupil in the eye (see photo), redistributing blood to the muscles and altering the body's metabolism, so as to maximise blood glucose levels (primarily for the brain).
Answer:
P-waves travel through liquids and solid while S-waves only travel through solids.
Explanation:
Scientists are able to use the fact that P-waves travel through both solids and liquids and waves travel through only solids to determine what makes the different layers of the Earth.
