suppose a spring of angular frequency 8.08 s" is compressed 0.100 m from
(10 = -0.100 m) but is given a shove to create a velocity in the +x direction of vo = 0.400 m/s
(a) the phase angle , (b) the amplitude a, and, (c) the displacement x as a function of time,
20.

The first law of thermodynamics states that heat added to a system is neither created nor destroyed but is transformed ⇒ as it changes into other forms of energy.

(a) calculate the number of electrons in a small, electrically neutral silver pin that has a mass of 10.0 g. silver has 47 electrons per atom, and its molar mass is 107.87 g/mol. (b) imagine adding electrons to the pin until the negative charge has the very large value 1.00 mc. how many electrons are added for every 109 electrons already present
