An airplane weighing 80,000. kg at takeoff reaches a speed of 880 km/h. What is the de Broglie wavelength in meters of the plane?

3.39 * 10^-41 m

Explanation:

Given that:

speed of airplane = 880 km/hr

Mass of airplane = 80000 kg

Debroglie wavelength (λ) = h / mv

h = planck's constant = 6.626 * 10^-34

; mass = 80000kg

Velocity = 880km/hr to convert to m/s

Velocity = (880 * 1000m) / 3600 =244.44 m / s

λ = (6.626 * 10^-34) /(80000*244.44)

λ = (6.626 * 10^-34) / 19555200

λ = 3.3889 *10^-41

λ = 3.39 * 10^-41 m

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.
