According to ohm’s law, which is stated as i = v ÷ r, which two sentences are true?

if the current increases, then the resistance increases. assume voltage is constant. if the resistance decreases, then the current increases. assume voltage is constant. if the voltage increases, then the resistance decreases. assume current is constant. if the voltage increases, then the current increases. assume resistance is constant. if the voltage increases, then the current decreases. assume resistance is constant.

The “death throes” of stars are amongst the most complex phenomena in all of astronomy, and the “corpses” of stars amongst the most energetic and exotic objects in existence. beginning at the end of the core helium fusion stage in a star’s life, describe in detail the post-main sequence development of both (a) a 1.0 solar mass star, and (b) a 25.0 solar mass star. in what significant ways do they differ? what role does each of these types of stars play in the "star-gas-star" cycle and the evolution of chemical elements in our galaxy?

Aquantity of gas has a volume of 1.5 m3 and an absolute pressure of 95 kpa. when the gas is compressed to a volume of 0.5 m3, what is the new absolute pressure of the gas? (assume that there’s no change in temperature.)

Acar moves at 12m/s and coasts up a hill with a uniform acceleration of -1.6m/s2. how far has it traveled after 6.0s?
