With the aid of a diagram, calculate parts a to c:
a. the current through a 10 m long 0.4mm thick nichrome wire if it is connected to a 24 v battery. (resistivity of nichrome is 100 x 10-8 ω.m).
b. how much power is transformed and how much is dissipated in the wire?
c. if the resistance of the wire in the previous question was taken at 20°c, at what temperature would the resistance of the nichrome wire increase by 10ω?

Note: the following questions are unrelated to the balmer series or the martian. refer to your course notes. a sun-sized star will spend most of its lifetime as a: white dwarf b. red giant c. protostar d. main-sequence star

Astudent is performing an experiment comparing sound and light waves. the student gathers the following data. what conclusion does the student most likely make based on this data? light waves always travel the same speed; however, the speed of sound is determined by the medium that it travels through. all sound waves always have the same energy, so the temperature of the medium does not affect wave speed. light needs to vibrate particles, so it travels fastest in tightly packed solids, while sound does not need a medium, so it travels fastest in a gas. tightly packed particles in solids slow down the light waves; however, sound waves make particles bounce into each other, so they travel faster in solids.
