How quiet are ellipticals?
I’m looking to buy an elliptical. I live in a third floor apartment with a thin floor (which is why I had to sell my treadmill) so I need to be sure they’re quiet enough that I won’t disturb my neighbours when I workout.
What should I look for when choosing one to be sure it’s quiet? I can spend about $800
Which of the following statements about the different types (shapes) of galaxies is correct?
Which of the following statements about the different types (shapes) of galaxies is correct?
All galaxies start out as ellipticals, but some later evolve to be spirals and irregulars.
Whatever type a galaxy is at its birth, that’s what it will be for all time.
What type we see a galaxy to be just depends on the angle at which
we happen to see it; all galaxies look roughly the same in shape.
90% of all galaxies are spirals (including our Milky Way); the other two types are very unusual.
Collisions and mergers between galaxies can sometimes change a galaxy’s type.
