It slowly cools an hardens,eventually turning into igneous rock<span />
Answer:

Explanation:
We define our values according to the text,
R= Radius
Velocity
Strenght of the vortex filament
From this and in a vectorial way we express an elemental lenght of this filmaent as
. So,

Where
imply a vector acting perpendicular to both vectors.
Applying Biot-Savart law, we have,

Substituting the preoviusly equation obtained,



So we can express the velocity induced is,

If you mean electromagnetic waves
Radio waves can be used well in radio signals
Infrared in remote controls
X rays for x-rays
Gamma rays in a nuclear power plant
Uv rays can cause cancer but they transmit vitamin D
Answer:
Rocks and pebbles that hit Earth's atmosphere and burn up are ______. ... an object in motion stays in motion unless acted upon by another force ... Kepler's Laws of Motion explain why ______. ... planets closer to the sun travel faster in their orbits than planets that are far away ... comets have long tails ... objects can move.
Explanation:
Answer:
H = 1/2 g t^2 time to reach top of trajectory
v = g t time to reach top of trajectory when v is initial speed upwards
v = 5 g = 49 m/s 5 sec upwards and 5 sec downwards
