Answer:
24.25m/s
Explanation:
m = 0.5kg
u ( initial velocity) = 0m/s
v ( final velocity) =?
a = 9.8m/s^2
d (displacement) = 30m
Since u don't have time, u only have the choice to use this formula
V^2 = u^2 + 2ad
V^2 = 0 + 2 x 9.8 x 30
V^2 = 588
V = 24.25 m/s
Solar system coalesced out of a swirling cloud of interstellar dust/gas is known as nebula gas theory
According to nebula gas theory, the Sun and all the planets of our Solar System began as a giant cloud of molecular gas and dust called solar nebula. Then, about 4.57 billion years ago, something happened that caused the cloud to collapse.
A shock wave from a nearby supernova explosion probably initiated the collapse of the solar nebula. The Sun formed in the center, and the planets formed in a thin disk orbiting around it.
Nebular Hypothesis: a widely accepted model. Originally formulated in 1755 by a German Philosopher Immanuel Kan. Its subsequent development has interwoven a variety of scientific disciplines including astronomy, physics, geology, and planetary science. The solar system coalesced out of a swirling cloud of interstellar dust/gas called nebula. Sun born from a nuclear reaction called nebula.

That depends on the wavelength itself, like what type of wave it is and where on the spectrometer it is
Gas is what thermal energy turn into when it is in a car
B) Distance: the farther, the weaker!
