Uniform acceleration, so the acceleration a is constant, and at the same time, due to:

VB? -Department of Veterans Affairs? =(VB+VA)(VB-VA)VC? -VB? =(VC+VB)(VC-VB)

Combine ③ and ④, and separate them to get:

(VB-VA)=2(VC-VB)

It is obtained from formula ③ and formula ④ respectively.

Voltammetry =6 Voltammetry

VC= 12-VB

Substitute into the above formula.
