When white light is diffracted and blue color is seen is due to the absorbance of wavelength of all other color except blue.
<u>Explanation:
</u>
- The white light diffracts into rainbow colors which are the 7 colors present in form of VIBGYOR.
- VIBGYOR is the violet, Indigo, Blue, Green, Yellow, Orange and Red.
- When the blue color is seen denotes the shortest wavelength being reflected and all other being absorbed at the specified location.
Answer:
The value is 
Explanation:
From the question we are told that
The velocity is ![a = 120 \ km/h = [tex]\frac{120 * 1000}{3600} = 33.3 \ m/s](https://tex.z-dn.net/?f=a%20%3D%20%20120%20%5C%20%20km%2Fh%20%3D%20%20%5Btex%5D%5Cfrac%7B120%20%2A%20%201000%7D%7B3600%7D%20%3D%20%2033.3%20%5C%20%20m%2Fs)

The time taken is 
The time taken for contact is 
The velocity of the of the car after contact is ![v_c = 71.0 \ km/h = [tex]\frac{71 *1000}{3600} = 19.7 2 \ m/s](https://tex.z-dn.net/?f=v_c%20%3D%20%2071.0%20%5C%20%20km%2Fh%20%3D%20%5Btex%5D%5Cfrac%7B71%20%2A1000%7D%7B3600%7D%20%3D%20%2019.7%202%20%5C%20%20m%2Fs)
[/tex]
From the equation of kinematics we have that
Here u = 0 \ m/s since the car is initially motionless
=> 
=>
Answer: touch the pan to the burner
Explanation:
There are three modes of heat transfer:
conduction, convection and radiation.
For conduction, the heat transfers from a hot object to a cold object when the two are in contact.
For convection there is bulk motion of fluid occurs which transfers the heat.
For heat transfer by radiation, medium is not required.
Thus, to demonstrate conduction between pan and burner, the pan must touch the burner.
