Jupiter's moon Io has active volcanoes (in fact, it is the most volcanically active body in the solar system) that eject materia

Mademuasel [1]

Answer:

91.5 km

Explanation:

Hi!

If we are to ignore the variation in gravity we can use the formula for teh potential energy near the surface of a planet:

mgh

If the energy of the material ejected from the volcano on Io's surface is the same on earth's surface we have:

$mg_{Io}h_{Io} =mg_{e}h_{e}$

where subindexes Io and e means Jupiter's moon Io, and Earth, respectively

solving for h_e

$h_{e} = h_{Io} \frac{g_{e}}{g_{Io}}$

The acceleration due to the gravity of a planet can be calculated as:

$g = G \frac{m}{R^2}$

Where R and m are the radius and mass of the planet

Therefore:

$h_{e} = h_{Io} (\frac{m_{Io}}{m_e})(\frac{R_e}{R_{Io}})^2$

m_e = 5,972 × 10^24 kg

R_e = 6 371 km

Replacing all given values:

h_e = 500 km *(0.183) = 91.515 990 km

What did isaac Newton believe light was made of

adelina 88 [10]

Sir Isaac Newton, held the theory that light was made up of tiny particles. In 1678, Dutch physicist, Christiaan Huygens, believed that light was made up of wavesvibrating up and down perpendicular to the direction of the light travels, and therefore formulated a way of visualising wave propagation.

a passing warm front changes air pressure. does a passing warm front increase or decrease air pressure

meriva

Warmer air has molecules more spread out, so I'd say a decrease in air pressure.
