what kind of question is this....anyways...
Yes, we are real and yes we do exist. Without God there would be no creation or any type of life on earth. So, yes because of God Himself the creator of us we exist.
By definition, refractive index is the ratio of the velocity of light in vacuum to the velocity of light in a specified medium. The medium here is the liquid. The speed of light through the liquid also depends on the temperature and pressure. At sea level, the liquid is higher in temperature and pressure. So, the speed is gonna be relatively slower because of the movement of atoms. At high altitude, the liquid is at a lower temperature and pressure. The movements of the molecules are lesser, thus, light can move much faster. So, yes, it would be different. The refractive index would be closer to 1 at high altitude, and greater than 1 at sea level.
Watch this ! You've never seen anything like it !
No wait. I'm pretty sure you have.
Weight = (mass) · (gravity)
Weight = (10 kg) · (9.8 m/s²)
Weight = (10 · 9.8) kg·m/s²
Weight = 98 Newtons
Out of the choices given, the best choice to explain the direction of the moving force of air is from area o high pressure to areas of low pressure. The correct answer is B.
For a standing wave to form, two waves must be traveling in opposite directions and cause destructive interference.
