Parallel rays of monochromatic light with wavelength 582 nm illuminate two identical slits and produce an interference pattern o

Airida [17]

Answer:

I = 0.56 10⁻⁴ W / m²

Explanation:

Double-slit interference is described by the expression

d sin θ = m λ

if we use trigonometry we can find the angle

tan θ= y / L

how the angles are small

tan θ = sin θ / cos θ = sin θ

sin θ = y / L

we substitute

d y / L = m λ

if we take into account that each slit also produces a diffraction phenomenon, the intensity distribution is the product of the intensity of the slits by the intensity of the diffraction process

I = I₀ cos² (d a) [(sin ba) / ba]²

a = π sin θ /λ

where the separation of the slits and b is the width of the slits

we substitute

I = I₀ [cos (d a)]² [sin ba /ba]²

a = π y / (L λ)

let's reduce the magnitudes to the SI system

λ = 582 nm = 582 10⁻⁹ m

L = 75.0 cm = 75.0 10⁻² m

d = 0.640 mm = 0.640 10⁻³ m

b = 0.434 mm = 0.434 10⁻³ m

Io = 4.40 10⁻⁴ W / m²

let's calculate for y = 0.710 mm = 0.710 10⁻³ m

a = π 0.710 10⁻³ / (75 10⁻² 582 10⁻⁹)

a = 5.11004 10³

I = 4.40 10⁻⁴ [cos (0.640 10⁻³ 5.11004 10³)]² (sin (0.434 10⁻³ 5.11004 10³) / (0.434 10⁻³ 5.11 10³)²

I = 4.40 10⁻⁴ cos² (3.2704) (sin 2.2178 / 2.2178)²

remember that the angles are in radians

I = 4.40 10⁻⁴ 0.9835 (0.79789 / 2.2178)²

I = 4.40 10⁻⁴ 0.9835 0.1294

I = 0.56 10⁻⁴ W / m²

Which statement describes the direction of spontaneous heat flow

NISA [10]

The direction of spontaneous heat flow in a system is described by the second law of thermodynamics, which describes that the direction of spontaneous heat flow is from a region of higher heat energy to a region of lower heat energy.
Multiple statements of this law are available, such as the one presented by Carnot or the one presented by Clausius and Planck.

Calcula la energía cinética der un vehículo de 1860kg 1ue se mueve a 50km/h

PtichkaEL [24]

Answer:

Kinetic energy of the vehicle is

$K = 1.79 \times 10^5 J$

Explanation:

Kinetic Energy of the vehicle is given as

$K = \frac{1}{2}mv^2$

now we have

m = 1860 kg

$v = 50 km/h$

$v = 50 \times \frac{5}{18}$

$v = 13.89 m/s$

now we have

$K = \frac{1}{2}(1860)(13.89)^2$

$K = 1.79 \times 10^5 J$

Four identical metallic objects carry the following charges 1.82 6.65 4.80 and 9.30 C The objects are brought simultaneously int

GuDViN [60]

Answer:

a) 5.64 C

b) 3.5*10¹⁹ protons

Explanation:

Since the four metallic objects are identical, and total charge must be conserved, this means that after brought simultaneously into contact so that each touches the others, once separated, total charge must be the same than before being brought in contact.
But due they are identical, after charges were able to transfer freely between them, the four objects must have the same final charge, i.e. the fourth part of the total charge, as follows:

$Q_{n} = \frac{Q_{tot}}{4} = \frac{22.57C}{4} = 5.64 C (1)$

This charge will be divided between n protons, since the charge is positive.
Since each proton carries a charge equal to the elementary charge e, which value is 1.6*10⁻¹⁹ C, we can find the number of protons in excess, doing the following calculation:
$n_{p} =\frac{Q_{n}}{e} = \frac{5.64C}{1.6e-19C} = 3.5 e19 C (2)$
