Answer:
It should be -5
Step-by-step explanation:
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:
No, This is not reasonable estimate.
Step-by-step explanation:
Charles wants to take out a 5 year loan on car that cost $15000.
He make rough estimate to make payment. He can afford to pay up to $200 per month.
First we find total number of months in 5 years.
Total months = 5x12= 60 months
Total estimate to pay = =$12000
we can see cost of a car $15,000 is greater than his estimation $12,000.
Therefore, Charles estimation will not work.
No, This is not reasonable estimate.
The complete question demands that we find B from; B = A+C
The expression which represents the polynomial B is; B = 20m +28n -32.
<h3>Addition of polynomials</h3>
The given polynomials are;
Since, B= A +C; we have;
- B = 6m + 2n-1 + 14m + 26n-31.
