Answer:
1.312 x 10⁻¹² J/nucleon
Explanation:
mass of ¹³⁶Ba = 135.905 amu
¹³⁶Ba contain 56 proton and 80 neutron
mass of proton = 1.00728 amu
mass of neutron = 1.00867 amu
mass of ¹³⁶Ba = 56 x 1.00728 amu + 80 x 1.00867 amu
= 137.10128 amu
mass defect = 137.10128 - 135.905
= 1.19628 amu
mass defect = 1.19628 x 1.66 x 10⁻²⁷ Kg
= 1.9858 x 10⁻²⁷ Kg
speed of light = 3 x 10⁸ m/s
binding energy,
E = mass defect x c²
E = 1.9858 x 10⁻²⁷ x (3 x 10⁸)²
E = 17.87 x 10⁻¹¹ J/atom
now,
binding energy per nucleon =
= 0.1312 x 10⁻¹¹ J/nucleon
= 1.312 x 10⁻¹² J/nucleon
B. Closed because otherwise the energy would "escape"
Answer:
Newton states his second law of motion in terms of momentum: The net external force equals the change in momentum of a system divided by the time over which it changes or F = m*a. The change in momentum is the difference between the final and initial values of momentum. ... It is equal to the change in momentum.

Answer:
The velocity of the cart when it reaches its greatest y coordinates is 10.135m/s
Explanation:Vx=0
0=6.8m/s+(6.2m/s^2)t
t=6.8/6.2
t= 1.1secs
Vy= 12m/s +(-1.7m/s^2 )t
Vy=12 +(-1.7×1.1)
Vy=12 -1.865)
Vy=10.135m/s
Which element is less reactive, an element whose atoms have seven valence electrons or an element whose atoms have eight valence electrons? Why?<span>an element with 8 valence electrons because it doesn't require any additional electrons to become stable</span>
