The easiest way to explain it is roughly identical to the way that your teacher explained it in class. If there were any easier way ... like writing it here in a few paragraphs ... then that's what the teacher would have done. You would have been given the easy explanation on the first day of class, printed on one sheet of paper, and you would have had the rest of the year to practice it and get really good at it.
If the class spent a month teaching it, then that's about how long it takes. Sorry.
Answer:
They all have frequency, wavelength, amplitude, speed and also all transfer energy.
Answer:
Net force will be 4.875 N
Explanation:
We have given mass of the cart m = 1.5 kg
Initial velocity of the cart = 0.2 m/sec
And final velocity of the car = - 0.125 m/sec ( Negative direction is due to opposite direction )
Instant of time ![\Delta t=0.1sec](https://tex.z-dn.net/?f=%5CDelta%20t%3D0.1sec)
Change in momentum is given by
![\Delta P=1.5\times (0.2-(-0.125))=1.5\times 0.325=0.4875kgm/sec](https://tex.z-dn.net/?f=%5CDelta%20P%3D1.5%5Ctimes%20%280.2-%28-0.125%29%29%3D1.5%5Ctimes%200.325%3D0.4875kgm%2Fsec)
Now force is given by
![F=\frac{\Delta P}{\Delta t}=\frac{0.4875}{0.1}=4.875N](https://tex.z-dn.net/?f=F%3D%5Cfrac%7B%5CDelta%20P%7D%7B%5CDelta%20t%7D%3D%5Cfrac%7B0.4875%7D%7B0.1%7D%3D4.875N)
Net force will be 4.875 N
