Refractive Index is a ratio of two similar physical quantity which is dimension less
refractive index = sin I / sin r

therefore it doesn't have a unit.

Refractive index is expressed as a ratio of speed of light in vacuum relative to the speed of considered medium. As it is a ratio and the units m/s or km/h cancel out each other. Therefore, the qauntity refractive index does not have any unit. I hope it will be helpful to you. Thank you

Describe the conditions necessary for sublimation to occur.
Verdich [7]

Answer:

Hi! Jimin! here!! ^^

Explanation:

Sublimation occurs more readily when certain weather conditions are present, such as low relative humidity and dry winds. Sublimation also occurs more at higher altitudes, where the air pressure is less than at lower altitudes. Energy, such as strong sunlight, is also needed. hope this will help you!!!

hope this helps!!

Which causes the thermocline?
Igoryamba
<span>Thermocline is a layer between warm water from the ocean’s surface and cool water from below the ocean. In here, the temperature decreases rapidly from the warmer layer to the colder layer.  A thermocline forms due to the heat of the sun heating the ocean’s surface. Because of the difference in density between warm and cooler ocean water, cooler ocean water sinks and warmer ocean water floats. This is caused due to the heat and mass transfer between particles of the ocean. The answer is letter C. The sun’s radiation does not extend below a certain depth; therefore, deeper ocean water is colder than surface water.</span>

An airplane in level flight travels horizontally with a constant eastward acceleration of 8.50 m/s2 and a constant northward acc
zloy xaker [14]

Answer:

d = 3574.3 m

Explanation:

Given that acceleration of the airplane is

a_x = 8.50 m/s^2

a_y = -28 m/s^2

initial velocity is given as

v_x = 83.5 m/s

v_y = -15.5 m/s

now we have displacement in x direction given as

x = v_x t + \frac{1}{2}a_x t^2

x = (83.5)(14) + \frac{1}{2}(8.5)(14)^2

x = 2002 m

Displacement along y direction is given as

y = v_y t + \frac{1}{2}a_y t^2

y = (-15.5)(14) + \frac{1}{2}(-28)(14^2)

y = -2961 m

so the magnitude of the displacement is given as

d = \sqrt{x^2 + y^2}

d = \sqrt{2002^2 + 2961^2}

d = 3574.3 m

Light from a 504-nm monochromatic source is incident upon the surface of fused quartz (n = 1.56) at an angle of 17°. What is the
PilotLPTM [1.2K]

Answer:

73 degree

Explanation:

Angle of incidence = 17 degree

According to the laws of reflection, the angle of incidence is equal to the angle of reflection.

So, angle of reflection = 17 degree

Angle from the surface = 90 - 17 = 73 degree
