Answer:
<h2>36 km</h2>
Explanation:
The distance covered by an object given it's velocity and time taken can be found by using the formula
distance = velocity × time
From the question we have
distance = 18 × 2
We have the final answer as
<h3>36 km</h3>
Hope this helps you

Speed=Distance/Time
Distance=40m,time=5.79seconds
S=40/5.79
=6.908m/s

Answer:
37.91594 keV
Explanation:
= Incident energy = 400 keV
θ = 30°
h = Planck's constant = 4.135×10⁻¹⁵ eV s = 6.626×10⁻³⁴ J s
Incident photon wavelength

Difference in wavelength


Final photon wavelength
