Answer:
<em>The frequency of the wave = 10 Hz.</em>
Explanation:
Wave: A wave is a disturbance that travels through a medium a transfer energy from one point to another in the medium without causing and permanent displacement of the medium itself.
V = λf .................. Equation 1
making f the subject of the equation,
f = V/λ.................... Equation 2
Where V = velocity of the wave, λ = wavelength of the wave, f = frequency of the wave.
<em>Given: V = 15 m/s², λ = 4.5 m.</em>
<em>Substituting these values into equation 2,</em>
<em>f = 15/1.5</em>
<em>f = 10 Hz.</em>
<em>Therefore the frequency of the wave = 10 Hz.</em>
*determining anyway the most important factors are intensity duration and isolation hope this hope this helps :)
Answer:
They are orbiting earth.So they stay in orbit.
We know that gravity increases with height.
Explanation:
1st Question Explanation:
- Earth's gravity still pull on them.
- Gravity combines with the satellite's momentum from its launch into space.This Combination cause the satellite go into the orbit.
2nd Question Explanation:
- Gravity is caused by the Earth's spinning
- Gravity is notable bless on high mountains or tall buildings.
