Answer:
PO(1) = PO(0) / 2 1 refers to 1 half life of PO(0)
PO(2) = PO(1) / 2 = P(0) / 4 amount of PO left after 2 half-lives
PO(3) = PO(2) / 2 = PO(0) / 8 amount of PO left after 3 half-lives
414 da / 138 da = 3 3 half-lives pass in 414 da
PO(0) = 8 PO(3) = 8 * 1.45E-4 g = 1.16E-3 g = .00116 g after 414 days
Answer:
Because due to hole water accumulated in the ship in the bottom must point causes shifting of gravitational point upward so their chance of sinking of <u>ship.</u>
Answer:
q = -7.691 ×
C
so magnitude of charge is 7.691 ×
C
and negative sign mean charge is negative potential
Explanation:
given data
electric potential = −2.36 V
distance = 2.93 mm = 2.93 ×
m
to find out
What are the sign and magnitude of a point charge
solution
we know here that electric potential due to charge is
V =
..............................1
here k is coulomb force that is 8.99 ×
Nm²/C² and r is distance and q is charge and V is electric potential
put here all value we get q in equation 1
V = 
-2.36 = 
q = -7.691 ×
C
so magnitude of charge is 7.691 ×
C
and negative sign mean charge is negative potential
