Some homes that use baseboard heating use copper tubing. hot water runs through and heats the copper tubing, which in turn heats aluminum fins. it is actually the aluminum fins that heat the air rising through the fins. how much energy would it take to heat a section of the copper tubing that weighs about 645.0 g , from 13.20 âc to 28.22 âc ? copper has a specific heat of 0.3850 (j/g)ââc.

Emagnitude of the electrical force acting between a +2.4 ×  10–8  c charge and a +1.8 ×  10–6  c charge that are separated by 0.008 m is    n, rounded to the tenths place.

First to answer will be the brainliest i need the answer asap

Two lasers are shining on a double slit, with slit separation d. laser 1 has a wavelength of d/20, whereas laser 2 has a wavelength of d/15. the lasers produce separate interference patterns on a screen a distance 5.30 m away from the slits. part a which laser has its first maximum closer to the central maximum? view available hint(s) which laser has its first maximum closer to the central maximum? laser 1 laser 2
