g The first step in the process is to calibrate the grating, so we know the grating spacing (the distance between the openings i
Trava [24]

Answer:

The grating spacing is  d = 1055nm

Explanation:

From the question we are told that

    The wavelength is  \lambda = 590 nm = 590 *10^{-9}m

    The angle is \theta = 34^0

    The  order of the spectrum is  n = 1

Generally in grating grating the condition for maxima   to occur is  

             d sin \theta  = n \lambda

where d is the grating spacing

     making d the subject of the formula

                  d = \frac{\lambda }{sin \theta }

        Substituting values

                  d = \frac{590 * 10^{-9}}{sin (34)}

                     d = 1055nm

What is the density of marble that has a mass of 4.3 g and a volume of 2.7 cm?
KiRa [710]

Explanation:

density(d) = mass(m) × volume(v)

given:

mass = 4.3 g = 0.0043 Kg

volume = 2.7 cm³ = 0.027 m³

= 0.0043 Kg / 0.0027 m³

= 0.15 Kg/m³

Which career best fits the group of words below?
Alik [6]

Answer:

The answer is "power dispatcher."

Explanation:

"Power dispatchers" are also known as <em>"power distributors</em>." Their field of work is related to controlling the distribution of electricity to the <em>"electrical substations." </em>These substations allow the transmission of electricity to step down from a higher voltage to a lower voltage.

Whenever there is an electrical problem, the power dispatcher also comes into play. They make sure that the power lines are intact and checks for possible damages when typhoons or earthquakes occur.

Thus, this explains the answer.
