Light of wavelength 510 nm is used to illuminate normally two glass plates 24.3 cm in length that touch at one end and are separ

Answer:

m = 180 \ bright \ fringes

Explanation:

From the question we are told that

    The  wavelength is  \lambda  =  510 \ nm = 510 *10^{-9} \  m

    The length of the of the plate is  l  =  24.3 \ cm  =  0.243 \  m

    The radius of the wire  is r=  0.023 \ mm  =  2.3 *10^{-5} \ m

Generally the diameter of the wire which is the distance between the glass  plates is mathematically represented as

             d =  2 *   r

=>          d =  2 *   2.3 *10^{-5}

=>          d =  4.6 *10^{-5} \  m

 Generally the condition for constructive interference is mathematically represented as

           2 *d = m \lambda

=>        m = \frac{2d}{\lambda}

=>        m = \frac{2 * (4.6* 10^{-5})}{ 510 *10^{-9} }

=>        m = 180 \ bright \ fringes

ss7ja [257]

Answer: Option (A) is the correct answer.

Explanation:

A corrective action is defined as the action with the help of which a person can avoid a difficulty or problem that he/she was facing earlier.

For example, when the chef checked the temperature of soup using thermometer then it was 120 but his operation's critical limit was 135.

So, to avoid this problem he heated the soup to 165 at 15 seconds following which he got the result as desired.

Therefore, reheating the soup was his corrective action.

Thus, we can conclude that reheating the soup was the corrective action.

"how do the fundamental laws of physics make manifest that space has 3 dimensions?"
bazaltina [42]
If you are asking for a proof on having at least 3 dimensions in space, you can find the physical proof anywhere in your daily life activities. Just the fact that solids have volumes is a proof already that we live in a three-dimensional space. We can move forwards, backwards, sidewards and in all other directions possible.

When you go right into detail, the fundamental laws governing these proofs are very technical. They have differential equations to show as proof. It is too detailed to discuss here. The important things is that, these fundamental laws are what explains the science in our basic activities and natural phenomena:

*Gravitation and planetary motion
* Translation, rotation, magnetic field, forces
* Integrals of equations:

A train whose proper length is 1200 m passes at a high speed through a station whose platform measures 900 m, and the station ma
TiliK225 [7]

Answer:

0.66c

Explanation:

Use length contraction equation:

L = L₀ √(1 − (v²/c²))

where L is the contracted length,

L₀ is the length at 0 velocity,

v is the velocity,

and c is the speed of light.

900 = 1200 √(1 − (v²/c²))

3/4 = √(1 − (v²/c²))

9/16 = 1 − (v²/c²)

v²/c² = 7/16

v = ¼√7 c

v ≈ 0.66 c
