Answer:

Reflected ray. A ray of light or other form of radiant energy which is thrown back from a nonpermeable or nonabsorbing surface; the ray which strikes the surface before reflection is the incident ray.

Answer:

In optics a ray is an idealized model of light, obtained by choosing a line that is perpendicular to the wavefronts of the actual light, and that points in the direction of energy flow.[1][2] Rays are used to model the propagation of light through an optical system, by dividing the real light field up into discrete rays that can be computationally propagated through the system by the techniques of ray tracing. This allows even very complex optical systems to be analyzed mathematically or simulated by computer. Ray tracing uses approximate solutions to Maxwell's equations that are valid as long as the light waves propagate through and around objects whose dimensions are much greater than the light's wavelength. Ray theory (geometrical optics) does not describe phenomena such as diffraction, which require wave theory. Some wave phenomena such as interference can be modeled in limited circumstances by adding phase to the ray .

How do molecules behave in a solid?
N76 [4]

Answer:

In the solid state particles are held closely together and vibrate slightly. They exist in a regular arrangement - there is no regular arrangement in the other states.

lidiya [134]

Answer:

4 km/hr

Explanation:

suppose 's' is Diane's speed with no current.

't' represents time in hrs.

Using the formula:

Distance = speed 's' x time 't'

-> when she swims against the current, equation will be,

5= (s-2)t

t= 5/(s-2)

->when she was swimming with the current, equation is,

15= (s+2) t

t= 15/(s+2)

equating eq(1) and (2)

5/(s-2) = 15/(s+2)

5s + 10 = 15s - 30

40= 10s

s= 40/10

s=4

Therefore, if there were no current, her speed is 4km/hr

Water flows upward in a pipe oriented at 30 degrees. The mercury manometer readsh= 12 cm. Bothfluids are at 20â—¦C. What is the
NISA [10]

Answer:

The pressure difference in the pipe is 2666 Pa.

Explanation:

Given that,

Height = 12 cm

Angle = 30°

We need to calculate the height

Using formula of height

h_{1}=2\tan30

h_{1}=1.154\ m

We need to calculate the pressure difference in the pipe

Using formula of pressure

P_{2}=P_{1}+\rho_{w}h-\rho_{Hg}h-\rho_{w}h_{1}

P_{2}-P_{1}=\rho_{w}h-\rho_{Hg}h-\rho_{w}h_{1}

Where, \rho_{Hg} = density of mercury

\rho_{w} = density of water

Put the value into the formula

P_{2}-P_{1}=(13600-1000)\times12\times10^{-2}+1000\times1.154

P_{2}-P_{1}=2666\ Pa

Hence, The pressure difference in the pipe is 2666 Pa.
