It is the the ecrins of light
Answer:
7,79 seconds
Explanation:
You need to use the acceleration formula. A is acceliration, 
is change in velocity and t is time.
You need to multiply the formula with t and divide by a and you get
a*t=
t= /a
after that you just need to insert the numbers
change in velocity is 76.4 minus 0.
acceliration is gravitational acceleration which is 9.81.
After that you get
t=76.4/9.81
t= 7,787971458 s
Answer:
Only main sequence stars have a well-defined relationship between spectral type and luminosity.
Explanation:
Low-mass stars have much longer lifetimes than high-mass stars.
the answer is a: galaxies. galaxy clusters are groups of galaxies that like to hang out together out there in space. the milky way's own galaxy cluster is called the local group.
Using the term c in this case is a little confusing. It is more generic to use a general velocity, v. That way, in this case, we know to use the speed of sound.
wavelength*frequency=v
wavelength_20Hz = (345 m/s)/(1/20s)
<span>wavelength_20kHz = (345 m/s)/(1/20000s)
