First, you must find the wavelength of the laser. You shine the laser into the interferometer and then move one of the mirrors u

ntil you have counted 100.0 fringes passing the crosshairs of the telescope. The extremely accurate micrometer shows that you have moved the mirror by 0.03164 millimeters. What is the wavelength λ of the laser?

Answer:

316.4 nm

Explanation:

wavelength λ of the laser = (the absolute value of the difference between the initial position and final position after the mirror has been moved ) / 100.0 fringes = 0.03164 mm ÷ 1000 = 0.00003164 m / 100 = 0.0000003164 m = 316.4 nm

An empty can of soda is yeeted (thrown) into a crowd. Then, a full can of soda is yeeted into a crowd. Throwing the full can too
4vir4ik [10]

Answer:

Newton's third law of motion.

Explanation:

We are told the force needed to throw the full soda can was more than that needed to throw the empty can.

Now, the weight of the full soda can will be more than that of the empty can. Therefore, the full can will demand more force than that of the empty can due to Newton's third law of motion which states that to every action, there is an equal and opposite reaction.

Blue light, which has a wavelength of about 475 nm, is made to pass through a slit of a diffraction grating that has 425 lines p
algol13

The angle of diffraction of the blue light that passed through a slit of a diffraction grating is 63.5⁰.

<h3>Angle of diffraction</h3>

The angle of diffraction of the blue light that passed through a slit of a diffraction grating is calculated as follows;

mλ = dsinθ

sin θ = mλ/d

sin θ = (1 x 425)/475

sin θ = 0.8947

θ = sin⁻¹(0.8947)

θ = 63.5⁰

Thus, the angle of diffraction of the blue light that passed through a slit of a diffraction grating is 63.5⁰.

the brakes applied to a car produces an acceleration of 6m/s^2 in the opposite direction to the motion. if the car takes 2s to s
Bogdan [553]

Answer:

acceleration= -6ms^-2

Explanation:

v = u + at \\ 0 = u + ( - 6 \times 2) \\ u = 12m {s}^{ - 1}

distance

s = ut +  \frac{1}{2} a {t}^{2}  \\ s = 12 \times 2 +  \frac{1}{2}  \times ( - 6) \times  {2}^{2}   \\ s = 12m

<h3>therefore distance = 12m</h3>
