What . Slides are placed upside down in a slide projector to correct for the _______ image produced. A. magnified B. inverted C.

Yuri [45]

<span>The correct answer is B. Inverted image. This is because of all the lenses and light refractions and what not. The same things happens with our eyes except our brains fix the inverted image automatically. Since there are no brains in a projector, you have to fix it on your own by putting it in reverse.</span>

Light from a laser (lambda= 406.192 nm) is used to illuminate two narrow slits. The interference pattern is observed on a screen

dsp73

Answer:

The spacing between the slits is $d = 0.00145m$

Explanation:

From the question we are told that

The wavelength of the light is $\lambda = 406.192nm = 406.192*10^{-9} m$

The distance of the slit from the screen is $D = 5.937 \ m$

The number of bright fringe is $n = 24$

The length the fringes span is $L = 39.835 mm = \frac{39.835 }{1000} = 0.0398 m$

The fringe width (i.e the distance of between two successive bright or dark fringe) is mathematically represented as

$\beta = \frac{\lambda D}{d}$

Where d is the distance between the slits

$\beta$ is the fringe width which can also be evaluated as

$\beta = \frac{L}{n}$

Substituting values

$\beta = \frac{0.0398}{24}$

$\beta = 1.660 *10^{-3}$

Making d the subject of formula in the above equation

$d = \frac{\lambda D}{\beta }$

Substituting values

$d = \frac{406.192 *10^{-9} * 5.937 }{1.660 *10^{-3}}$

$d = 0.00145m$

Calcula el trabajo que realiza la fuerza de fregamiento sobre un cuerpo de 13kg que es desplaza una distáncia de 46 m si el coef

ZanzabumX [31]

Answer:

Los datos que tienes son:

m = 13 kg

d = 46 m

∪ = 0,45

g = 9,8 m/s²

Fr = ?

w = ?

Lo primero que haremos que calcular Fr

Fr = ∪mg

Fr = (0,45) (13 kg) (9,8 m/s²)

Fr = 57,33 N

Calculamos el trabajo realizado.

w = Fd

w = (57,33 N) (46 m)

w = 2637,18 Joules

Respuesta.

El trabajo realizado es 2637,18 Joules
