Observations of radio waves from astronomical objects suffer from poorer resolution than visible observations with the same size dish (or mirror) because Observations of radio waves from astronomical objects suffer from poorer resolution than visible observations with the same size dish (or mirror) because radio telescopes don't use solid mirrors. it is very difficult to detect radio waves. the signals are so weak in the radio region. radio telescopes are generally much smaller in diameter than optical telescopes. the wavelength of radio waves is much longer than the wavelengths of visible light.

Why is the energy that results from a roller coaster's position at the top of a hill referred to as potential energy?

Both independent and dependent clauses

Aflask with vinegar in it has a mass of 160 grams. a balloon with baking soda in it has a mass of 40 grams. the balloon is attached to the flask to seal the opening and the vinegar and baking soda mixes. the balloon inflates to a large volume. what will the total mass of the balloon and flask be after the balloon inflates? explain. a) less than 200 grams because the solid baking soda disappears. b) 200 grams, because all the atoms remain in the balloon or flask. c) more than 200 grams because the size of the balloon is so much larger. d) less than 200 grams because gases such as the one in the balloon are lighter than solids and liquids.
