The number of protons an element has is its atomic number so the atomic number would be 29
1. 2700 joules
2. im not sure about this one give me a sec
There are four (4) kinematic equations, which relate to displacement, D, velocity, v, time, t, and acceleration, a. Kinematic Equations Formula Questions
v=v0+at. v = v 0 + at.
d=12(v0+v)t d = 1 2 ( v 0 + v ) t or alternatively vaverage=dt. v average = d t.
d=v0t+(at22)
v2=v20+2ad.
Hope this helps ;)
