What is the total negative charge, in coulombs, of all the electrons in a small 1.20 gg sphere of carbon

When would a bouncy ball have the most potential energy

Ineed this asap part i: scientific method what is the difference between science and pseudoscience? what is the scientific method?

100 grams of molten lead (600°c) is used to make musket balls. if the lead shot is allowed to cool to room temperature (21°c), what is the change in entropy (in j/k) of the lead? (for the specific heat of molten and solid lead use 1.29 j/g⋅°c; the latent heat of fusion and the melting point of lead are 2.45 × 104 j/kg and 327°c, respectively.)
