Answer: Analog transfer information quicker, example electromagnetic waves which are used in our modern day phones.
Explanation: Digital signals are a more reliable form of transmitting information because an error in the amplitude or frequency value would have to be very large in order to cause a jump to a different value. Signals are composed of infinite possible values. Signals are composed of only two possible values: 0 or 1.
Answer:
D 500 N
Explanation:
As the velocity is constant the scale reads the same whether at rest, or at a fixed velocity. The only thing that would make the scale read differently would be a vertical acceleration.
Answer:
In longitudinal waves, such as sound, the vibration is parallel to the propagation direction of the wave itself. These disturbances are due to the successive compressions of the medium, where the particles move back and forth in the same direction as the wave.
If we want to measure the amplitude of this type of wave we need to know the distance between particles of the medium that is being compresed by the perturbation. So, <em>the closer together the particles are, the greater the amplitude of the wave</em>.
There's actually only one latitude implied by anything attached the question . . . Zero, since there are no choices listed.
That's brilliant ! Because zero latitude (the equator) IS the place on Earth where tangential speed is greatest.
Very clever !
