Answer:

D. all of these

Explanation:

Electric forces, gravitational forces and magnetic forces are non contact forces. These forces are also the fundamental forces. Non contact forces are the forces which applied on a body without any real touch. Generally these non contact forces are in equilibrium.

Use V=Voe^-t/RC and T=RC to derive T1/2=Tln2
Ksju [112]
Enclosed is some guidance algebra.I find this q a little confusing. It quotes "RC" which usually makes me think of electrical circuits and time constants based on converting calculating RC value and equating that to t for one time constant then 2RC for two time constants etc. The theory being that after 5 time constants - 5RC - a circuit is stable. BUT, this q then goes on to mention HALF LIFE. The curves for both half life and time constant are both exponential, as in the number e to the power of something, but the algebra is slightly different. I hope my algebra is ok.
