Enough heat and pressure
I hope this helps.
OD is the answerrr don’t worry i think i took this clas
Answer:
I = 2.18 10⁻⁴ W / m²
Explanation:
The two-slit interference pattern is described by the expression for constructive interference.
d sin θ = m λ
If we also want to know the distribution of intensities we must perform the su of the electric field of the two waves, and find the intensity as the square of the velvet field, obtaining the expression
I = I_max cos² ((π d /λ
L) y)
where d is the separation of the slits, λ the wavelength, L the distance to the screen e and the separation of the interference line with respect to the central maximum
let's reduce the magnitudes to the SI system
λ = 583 nm = 583 10⁻⁹ m
L = 75.0 cm = 75.0 10⁻² m
d = 0.640 mm = 0.640 10⁻³ m
y = 0.900 mm = 0.900 10⁻³ m
let's calculate the intensity of this line
I = 5 10⁻⁴ cos² ((π 0.640 10⁻³ /583 10⁻⁹ 0.75 10⁻²) 0.900 10⁻³)
I = 5 10⁻⁴ cos2 (413.84)
I = 5 10⁻⁴ 0.435
I = 2.18 10⁻⁴ W / m²

<span>. Density is a value for
mass, such as kg, divided by a value for volume, such as m3. Density is a
physical property of a substance that represents the mass of that substance per
unit volume. To calculate the density of mars, we need its mass and its volume. We calculate as follows:
mass of Mars = </span><span> 6.40 × 10^23 kg
volume of Mars = 4</span>πr³ / 3 (assuming the planet is a sphere)
r = 3395 km = 3395000 m
= 4π(3395000 m)³ / 3
= 1.64 x 10^20 m^3
Density = mass / volume
Density = 6.40 × 10^23 kg / 1.64 x 10^20 m^3
Density = 3904.56 kg/m^3
Therefore, the density of the planet Mars is 3904.56 kg/m^3.
