Answer:
t = 33.63 minutes
Explanation:
Given that,
Output power, P = 470 W
Mass of the cyclist, m = 88 kg
Height of the mountain stage, h = 1100 m
To find,
Time taken to reach the cyclist
Solution,
The rate of doing work is called power delivered. Its formula is given by :
W is the work done
W = mgh
t = 2018.38 seconds
or
t = 33.63 minutes
So, the time taken by the cyclist is 33.63 minutes. Hence, this is the required solution.

The angles for the first-order diffraction of the shortest and longest wavelengths of visible light are 22.33 ⁰ and 49.46 ⁰ respectively.
<h3>Angle for the first order diffraction</h3>
The angle for the first order diffraction is calculated as follows;
dsinθ = mλ
sinθ = mλ/d
<h3>For shortest wavelength (λ = 380 nm)</h3>
d = 1/10,000 lines/cm
d = 1 x 10⁻⁴ cm x 10⁻² m/cm = 1 x 10⁻⁶ m/lines
sinθ = (1 x 380 x 10⁻⁹)/(1 x 10⁻⁶)
sinθ = 0.38
θ = sin⁻¹(0.38)
θ = 22.33 ⁰
<h3>For longest wavelength (λ = 760 nm)</h3>
sinθ = (1 x 760 x 10⁻⁹)/(1 x 10⁻⁶)
sinθ = 0.76
θ = sin⁻¹(0.76)
θ = 49.46 ⁰
