It is the study of cognitive functions.
Answer:
Vibrations of electric and magnetic fields.
Vibration of air particles
Vibration of the water particles.
Explanation:
We have here two groups of waves. Electromagnetic wave and mechanical waves.
- For the first one, electromagnetic waves, energy is transferred through vibrations of electric and magnetic fields.
- For the second group, mechanical waves as a sound, for instance, energy is transferred through vibration of air particles or particles of a solid through which the sound travels. Or In water waves, energy is transferred through the vibration of the water particles.

Answer:
0.99m
Explanation:
Firs you calculate the relative velocity between the boat and the wave. The velocity of the boat is 5m/s and the velocity of the wave is given by:
the relative velocity is:
This velocity is used to know which is the distance traveled by the boat after 20 seconds:
Next, you use the general for of a wave:
you take the amplitude as 2.0/2 = 1.0m.
by replacing the values of the parameters in f(x,t) you obtain the vertical displacement of the boat:
B
The Ardi fossil is believed to be 4.4 million years old, providing evidence that humans have been on Earth for 4 million years.
