What is the total charge of all the electrons in a 14.9 kg bar of gold? (Hint: gold has 79.0 electrons per atom and an atomic mass of 179 u.)

Iwould sure like to answer your question but i honestly just don’t know

Wish i knew this to !

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.

The sample with the lowest specific heat capacity will have the greatest temperature increase. in this case, it would be platinum.
