Modern quantum theory tells us that all matter can be described as a wave with a wavelength described by the equation
wavelength=h/p
Where h is Planck's constant (6.63*10^-34 J*s) and p is the momentum (mass times velocity). Using the fact that a neutron has a mass of 1.67*10^-27 kg we can write the equation
80*10^-12 m = 6.63*10^-34 /(1.67*10^-27 kg *v)
Solving this for v we got that the required velocity would be 4862.57 m/s.

What is the wave distance between 21 crest is 80mm?
The wavelength can be calculated by dividing the distance between 21 crests (80 mm) by the number of crests. In this case, the wavelength would be 80 mm / 21 crests = approximately 3.81 mm.
What is the speed of a wave when the frequency of the wave is 80 hertz and 16 cm?
The speed of a wave can be calculated using the formula v = fλ, where v represents the speed of the wave, f is the frequency (80 Hz), and λ is the wavelength (16 cm). Simply multiply the frequency and the wavelength to find the speed of the wave.
What is the acceleration of the car if the velocity of a car increases by 40 ms in 80 seconds?
The acceleration of the car is 0.5 m/s^2. This is calculated by dividing the change in velocity (40 m/s) by the time taken (80 seconds).
A plane traveling at 80 ms lands on a runway and comes to rest after 10 seconds What was the plane's deceleration?
The plane's deceleration can be calculated using the equation: acceleration = change in velocity / time taken. The plane's initial velocity is 80 m/s, final velocity is 0 m/s, and time taken is 10 seconds. Therefore, the deceleration is 8 m/s^2.
What is the velocity of a car increases by 40 ms in 80 seconds. What is the acceleration of the car A. 0.5 ms2 B. 0.25 ms2 C. 120 ms2 D. 40 ms2?
The acceleration of the car can be calculated using the formula: acceleration = (change in velocity) / time. In this case, the change in velocity is 40 m/s and the time is 80 seconds. Therefore, acceleration = 40 m/s / 80 s = 0.5 m/s². So, the correct answer is A. 0.5 m/s².
A truck is traveling east on a highway at 80 km h What is velocity?
Velocity is speed and direction. Truck speed is 80 km/hr. Truck velocity is 80 km/hr going east. Its velocity is also -80 km/h going west, and 0 km/h going north or south.
A man who is walking has a momentum of 80 kilogram meters per second west The man has a mass of 80 kilograms which is the velocity of the man?
Momentum = mass * velocity. We are told that his momentum is 80kgm/s, and that his mass is 80 kg, so we can say: 80kgm/s = 80 kg × V ∴ 1m/s= V So the velocity of the man is 1 meter per second west.
What is the wave distance between 21 crest is 80mm?
The wavelength can be calculated by dividing the distance between 21 crests (80 mm) by the number of crests. In this case, the wavelength would be 80 mm / 21 crests = approximately 3.81 mm.
Max jogged 80 meters north in 10 minutes what was his velocity?
80/10 = 8 metres per minute
How many neutron does Ga80 have?
It has 49 neutrons, 80 mass number (protons and neutrons) and 31 atomic number(protons) so 80-31=49.

PROBLEM: A female vocalist with an alto voice can sing as low as 80 Hz. Given that the speed of sound is 265 m/s, what is the wavelength of the sound waves?
λ = c / f (wavelength = speed of sound / frequency) λ = 265 / 80 λ = 3.3125 m
How do subtract 80 percent from a number?
To subtract 80 percent from a number, first calculate 80 percent of that number by multiplying it by 0.80. Then, subtract the result from the original number. For example, if the number is 100, you would calculate 80 percent as 100 × 0.80 = 80, and then subtract: 100 - 80 = 20. The final result is the number after subtracting 80 percent.
