Iron-56 has the greatest binding energy per nucleon while Hydrogen-3 has the lowest based on the information in the graph of average binding energy per nucleon against number of nucleons in nucleus. We know that the the greater the amount of binding energy per nucleon the greater the nuclear stability is, thus Iron-56 is the most stable atom among Helium-4, Uranium-238 and Hydrogen-3.
Convection is the circular motion that occurs as hotter air or liquid increases when the cooler air or liquid drops down, and has faster moving molecules, rendering it less dense. Convection currents within the earth shift layers of magma, and currents are formed by convection in the ocean.
Answer:
v = 1.69 m/s
Explanation:
Given that,
Displacement of the student is 304 m due North and it takes 180 s.
We need to find the student's average velocity. Using formula of velocity.
Velocity = displacement/time
Hence, the student's average velocity is 1.69 m/s.
Answer:
(a). 2
(b). 1/3
(c). 11.11
Explanation:
(a). k= (t₍s₎-t₍o₎)/t₍o₎...............(1)
where k= retention factor,
t₍o₎=solvent time, t₍s₎= solute time.
Given t₍s₎=9.0 Minutes, t₍o₎=3.0 minutes.
∴ k= (9-3)/3
k= 2.
(b). the fraction of time the solute spend in the mobile phase in the column is the ratio of the solvent time to the solute time. = t₍o₎/t₍s₎..........(2)
= 3/9
=1/3.
(c). K=k(Vm/Vs)................(3)
where K= partition coefficient, k= retention factor, Vm=volume of mobile phase, Vs= volume of stationary phase.
∴K = k(Vm/Vs)
k=2, and Vs=0.18Vm.
∴K = 2(Vm/0.18vm)
⇒K = 2/0.18
∴K=11.11
