Answer:
The total momentum is 
Explanation:
The diagram illustration this system is shown on the first uploaded image (From physics animation)
From the question we are told that
The mass of the first object is 
The speed of the first mass is 
The mass of the second object is 
The speed of the second object is assumed to be 
The total momentum of the system is the combined momentum of both object which is mathematically represented as
substituting values
Answer:
5 miles a second
Explanation:
20 divided by 4
hope it helps and for brainliest :)
The only thing we know of so far that can shift light to longer wavelengths is the "Doppler" effect. If the source and the observer are moving apart, then the observer sees wavelengths that are longer than they should be. If the source and the observer are moving toward each other, then the observer sees wavelengths that are shorter than they should be. It works for ANY wave ... sound, light, water etc. The trick is to know what the wavelength SHOULD be. If you know that, then you can tell whether you and the source are moving together or apart, and you can even tell how fast. If the lines in a star"s spectrum are at wavelengths that are too long, then from everything we know right now, the star and Earth are moving apart.
Explanation:
Given data
Velocity v=3 m/s
Water volume flow rate V=590 m³/s
Water elevation z=90 m
Water density p=1000 kg/m³
First we need to determine the energy per unit mass
So
Now the power generation potential is:
