I'm not sure about the distance to the nearest star, but it's probably about        4 light-years (L-y).

1 L-y = 1.86 * 10E5 mi/sec * 3600 sec/hr * 24 hr/day * 365 day/yr

1 L-y = 5.9 *10E12 mi   and 4 L-y = 2.3 *10E13 mi    distance to star

2.3 * 10E13 mi / 900 mi/hr = 2.6 * 10E10 hr       hours to star

2.6 * 10E10 hr / (24 hr/day) = 1.1 * 10E9 day     days to star

1.1 * 10E9 day / 365 day/yr = 3 * 10E6 yr = 3 million years to star

One way to measure how long Jupiter takes to rotate is to watch the giant storms in its atmosphere go around. A more fundamental
DedPeter [7]

A more fundamental way to measure the rotation of Jupiter is to measure the changes in the planet's radio waves, which are controlled by its magnetic field.

<h3>Rotation of Jupiter</h3>
  • Jupiter, in contrast to the inner terrestrial planets, is a sphere made almost completely of hydrogen and helium. There are no craters or mountains that spin into view after a set amount of time on Jupiter, unlike Mars or Mercury, which you can follow to determine the rotation speed.
  • Out of all the planets in the Solar System, Jupiter rotates the most quickly. Given that Jupiter is also the largest planet in the Solar System, this is quite an accomplishment because it is rapidly rotating a vast amount of mass.
  • The planet's equator protrudes due to its rapid spin. Jupiter doesn't appear to be a perfect sphere; rather, it resembles a squashed ball. Even with a modest telescope in your backyard, you can see the bulge at the equator.
  • Observing the enormous storms that circle Jupiter's atmosphere can help determine how long it takes for Jupiter to revolve. Monitoring the variations in the planet's radio waves, which are governed by its magnetic field, is a more basic technique to gauge the rotation.

Use wave equation calculate the speed of sound in the air if frequency of 110 hz has a wave length of 3 m
kirill115 [55]
Answer = 330 m/s

The wave equation is as follows:

Wave speed = wavelength x frequency

The known values are:
Wavelength = 3m
Frequency = 110 Hz

Substitute the known values into the wave equation to find the wave speed.

Wave speed = 3 x 110

Wave speed = 330 m/s
