Reflection, i<span>t is the phenomena of getting back the light you've shown from a light source with the same angle. r</span>efraction, <span>It is the phenomena of bending of light when it changes it medium. This </span>can<span> rarer to denser or denser to rarer. d</span>iffraction,<span> It is the phenomena of bending of light near the edges of the object. hope this helps

The ransom note in the Lindbergh kidnapping case included some obvious spelling errors and other foreign and regional language.
Dimas [21]

Answer: The FBI used a technique which is called Latent Fingerprint Identification: a silver nitrate solution was used to cause a reaction of the unseen fingerprints perspiration left by the kidnappers all over the ransom notes. The reaction caused the perspiration to turn into silver chloride. This substance is white and it is also visible to the naked eye which means the fingerprints of the perpetrators were easily identifiable.

sorry if this is wrong, i hope i helped

The wind is blowing horizontally at 30 m / s in a storm at P o , 20°C toward a wall, where it comes to a stop (stagnation) and l
aleksklad [387]

Answer:

 To=20.44 °C    

Explanation:

Given that

Velocity , v= 30 m/s

Temperature , T= 20°C

We know that specific heat capacity for air ,Cp=1.005 kJ/kg.K

By using energy conservation ,the stagnation temperature is given as

T_0=T+\dfrac{v^2}{2C_p}

Now by putting the values in the above equation we get

T_0=(20+273)+\dfrac{30^2}{2\times 1.005\times 1000}\ K

To= 293.44 K

To= 293.44 - 273 °C

To=20.44 °C

Therefore the stagnation temperature will be 20.44 °C.
