1. Stop transmitting start and stop sending photons. This is typical morse code like transmissions of information. By varying the pattern of starts stops you vary the information sent. Also used in digital communications over radios, modems, and pulse dialing over radio/phones.
<span>2. Change the frequency. You use a pattern of shorter and longer wavelengths of radio waves higher and lower energies of individual photons to transmit information. This is frequency modulation </span>
The huge truck has a larger change in its momentum.
As they are moving at the same speed, the huge truck's mass is much higher and therefore its momentum change is greater.
Salt is made in in the water the seaweeds have slat on them of you let the seaweeds dry you can see the salt on them.
