The correct answer is:
<span>C: in the protons and neutrons of an atom
In fact, the nuclear energy refers to the binding energy of the nucleons (protons and neutrons) of an atom. The protons and the neutrons are held together by the strong nuclear interaction, one of the four fundamental forces of nature, and the energy associated to this interaction is called nuclear energy.

Answer:
True, people would actually pray to Poseidon for safe sea travel
Explanation:
Let us assume that piece 1 is 
is facing west side. And, piece 2 is 
facing south side.
Let 
= m and 
= 2m. Hence,
= 10.5 m/s
= 10.5 m/s
= 
= 14.84 m/s
or, = 15 m/s
Hence, the speed of the third piece is 15 m/s.
Now, we will find the angle as follows.
= 
= 
= 
Therefore, the direction of the third piece (degrees north of east) is north of east.
Answer:
Net capacitance
=
let net capacitance be R
1/R = 1/10+1/10
1/R=2/10
1/R=1/5
cross mutiply
R=5
the net capacitance is 5ohms
Answer:
h ’= 0.51356 m
Explanation:
For this exercise we can use conservation of energy
starting point. Highest point of the trajectory
Em₀ = m g h
sin θ = h / L
h = L sin θ
Em₀ = m g L sin θ
final point. Lowest point of the trajectory
Em_f = K = ½ mv²
as there is no friction, energy is conserved
Em₀ = Emf
m g L sin θ = ½ m v²
sin θ = ½ v² / gL
sin θ = ½ 3.80² / (9.8 6.60)
sin θ = 0.111626
tea = 6.41
They ask us for the speed for L ’= 4.60 m
let's find the height
sin 6.41 = h '/ L'
h ’= L’ sin 6.41
h ’= 4.60 sin 6.41
h ’= 0.51356 m
we use conservation of energy
m g h ’= ½ m v’2
v ’= √ (2gh’)
v ’= √ (2 9.8 0.51356)
v ’= 3.173 m /s²
