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 speed of a wave when the frequency of the wave is 80 hertz and 16 cm?
Wave speed = (frequency) x (wavelength) = (80 per second) x (0.16 meter) = 12.8 meters/second
What is the acceleration of a vehicle that changes its velocity from 80 km h to a dead stop in 13 s?
As velocity is reduced, acceleration is negative. Acceleration = change in velocity / time taken Velocity is m/second is got by multiplying 80 km p h by a fraction 5/18 which gives 200/9 m/s 200/9 is divided by 13s would give the required acceleration. That equals 1.7094 m/s2 So the retardation is 1.7094 m/s2
What force exert by parachutes?
Drop any object from a plane and the downward force due to the mass will eventually be matched by an upward force due to air resistance (terminal velocity). This terminal velocity depends on the objects drag coefficient, what the parachute does is present a drag coefficient sufficient to give the required terminal velocity for landing . > You need no more than say 6 metres / second landing velocity, effectively this is the terminal velocity with the chute open. Using body mass of 80 kg and acceleration due to gravity of 10 (m/s)/s, this gives a downward force of ( 80 * 10 ) 800 newtons. To balance this at landing velocity, you need a drag coefficient calculated from: 800 = velocity2 * drag coefficient , so: drag coefficient = 800 / velocity2 = 22.22 > Compare this to the pre chute deployment velocity of around 80 metres / second, giving a drag coefficient of: drag coefficient = 800 / 6400 = 0.125
When you are describing the rate that a race car goes around a track should you use the term speed or velocity to describe the motion?
Since velocity is speed with direction, you would use speed in reference to average rate of change of position, since the direction keeps changing. You can use velocity in reference to instantaneous speed, since a car is going in a specific direction at each instant in time.Examples:80 km/h is a speed.80 km/h due north is a velocity.
A rock is dropped from a height of 80 m and is free fall what is the velocity of the rock as it reaches the ground 4.0 secounds later?
39 m\s downward
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.
Max jogged 80 meters north in 10 minutes what was his velocity?
80/10 = 8 metres per minute

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 you calculate the area of 120 feet by 80 feet?

A plane can travel with a speed of 80 mi-hr with respect to the air determine the resultant velocity of the plane magnitude only if it encounters a 10 mi-hr headwind?
sol:- resultant velocity of a plane=80-10 =70m/s
Calculate 80 percent and 82.54 percent how do you calculate the avg?
The average is the sum of the elements divided by the number of elements In other words, 80%+82.54% then divide the sum by 2.
How do you calculate one third of 80 percent?
Divide 80 by 3 and get avbout 27 (26.666...) 27%
