I want to improve my speed
The minimum frequency is

while the maximum frequency is

Using the relationship between frequency f of a wave, wavelength

and the speed of the wave v, we can find what wavelength these frequencies correspond to:


So, the wavelengths of the radio waves of the problem are within the range 188-545 m.
Answer
I think most see black and white.
It's average speed during that 26 seconds was about 4.77 m/s. Without seeing the graph, we can't tell if it was going faster or slower at any particular time during that period. All we can tell is its average for the full interval.
Answer: 11
Explanation: In addition to nuclear reprocessing units at Sellafield and Urenco's Tails Management Facility (TMF) in Capenhurst, the UK has 11 active nuclear reactors in five locations (10 advanced gas-cooled reactors (AGR) and one pressurised water reactor (PWR)).
Please give brainliest or whatever brainlyest if this has helped :)
