Maria designed an experiment with flour, water, and cherries. The steps of the experiment are listed below.
Mix 250 grams of flour with 10 cherries and a tablespoon of baking powder.
Add some water to the mixture and make dough.
Place the dough in an oven.
Observe how the position of cherries changes when the dough gets baked.
Which of these can be best verified with the help of Maria's experiment?

the mass of the universe increases when it expands
the stars move towards Earth when the universe expands
the temperature of the universe increases when it expands
the density of particles in space decreases when the universe expands
@Festinger do you think you can help me with this

Answer 21

the density of particles in space decreases when the universe expands

mass is the same because nothing is created/destroyed
volume increases because of the baking powder.

with the same mass but larger volume density decreases.

Answer 22

Yayyyyyy thanks so much I was right!!!! I am getting smarter as you are

Answer 23

Professional research telescopes should be large enough to gather sufficient radiation from space. Which of these statements best explains why a reflecting telescope is is best used as a professional research telescope?

Bigger lenses are easier to manufacture and they produce less distortion.
Mirrors of reflecting telescopes gather harmful radiations from space.
Reflecting telescopes reflect away more radiation and distort images.
The series of mirrors and lenses help to reduce distortion of images.
