You could try multiplying each side of the equation by -6 .
Try that and let us know how it works out for you.
Answer:
152 photons
Step-by-step explanation:
Data provided in the question:
wavelength of the green light, λ = 550 nm = 550 × 10⁻⁹ m
Total energy = 5.50 × 10⁻¹⁷ J
Now,
Energy =
here,
n = number of photons
h = Plank's constant = 6.63 × 10⁻³⁴ J.s
c = speed of light = 3 × 10⁸ m/s
Therefore,
5.50 × 10⁻¹⁷ J =
or
( 5.50 × 10⁻¹⁷)( 550 × 10⁻⁹) = n(6.63 × 10⁻³⁴)(3 × 10⁸)
or
3025 × 10⁻²⁶ = n(19.89 × 10⁻²⁶ )
or
n = 152.086 ≈ 152 photons
Answer:
it means the value of x
Step-by-step explanation:
Answer:
point-slope form: y - 1 = -4/5(x - 8)
slope-intercept form: y = -4/5x + 7.4
Step-by-step explanation:
Find slope using the points (8, 1) and (-2, 9):
m = (y₂ - y₁) / (x₂ - x₁)
= (9 - 1) / (-2 - 8)
= 8 / -10
m = -4/5
Find y-intercept using slope m from above and anyone of the given points, let's use (8, 1):
y = mx + b
1 = -4/5(8) + b
1 = -6.4 + b
b = 7.4
Use slope m and y-intercept b above to form equation of line in slope-intercept form:
y = mx + b
y = -4/5x + 7.4
For point slope form use slope m from above and a point, again let's use (8, 1):
y - y₁ = m(x - x₁)
y - 1 = -4/5(x - 8)
