The process of changing from one phase of matter to another is a physical matter.
Answer: 1.5×10^10 N/C
Explanation:
E= F/q
Where E= magnitude of the electric field
F= force of attraction
q= charge of the given body
Given F= 6.5×10^-8 N
q= 4.3× 10^-18 C
Therefore, E = 6.5×10 ^-8/ 4.3×10^-18
E = 1.5×10^10 N/C
I think b but I’m not completely sure
I believe you are right. pH is the concentration of H+. Therefore the more acidic the more H+.
Wings to fly. Without flying, birds would be near defenseless.
