Answer: at night when the full moon is there the tide begans to appear higher
Explanation:
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.
I hope it helps you!
Yes this is true this causes day and night
T2=r In the form of Kepler's law that can use to relate the period T and radius of the planet in our solar systems
<u>Explanation:</u>
<u>Kepler's third law:</u>
- Kepler's third law states that For all planets, the square of the orbital
period (T) of a planet is proportional to the cube of the average orbital radius (R).
- In simple words T (square) is proportional to the R(cube) T²2 ∝1 R³3
- T2 / R3 = constant = 4π ² /GM
where G = 6.67 x 10-11 N-m2 /kg2
M = mass of the foci body
Let u = upward initial speed of the flea.
At the maximum height of h = 0.550 m, the vertical velocity is v = 0.
Therefore, from the formula
v² = u² - 2gh,
obtain
0 = u² - 2*(9.8 m/s²)*(0.55 m)
u² = 10.78 m²/s²
u = 3.283 m/s
Answer: The initial upward speed is 3.28 m/s (nearest thousandth)
