In order for the rope to be perfectly horizontal, there must be a vertical component in tension
Answer:
I do believe her actions were justified.
Explanation:
Due to the school charging extra fee from her father who makes a modest amount as a teacher. There was sum of money involved that could change how he lived and her.
I do not believe her actions where justified
She had a lot going for her. She could have skipped the hardship of helping grace and pass. She could have easily have gotten a good job with a degree and paid back all the debts owed. Alot of troubles could have been avoided just by doing her own thing.
1. Boiling water
2. Hair straightener or curler
Answer:
Explanation:
The sum of the kinetic and electric potential energies of the proton when initially released must be equal to their sum at infinity, so we have:
Which, since 
because initially the proton is at rest, is:
where 
is Coulomb's constant, 
the charge of the proton, 
the charge of the gold nucleus, since it has 79 protons, 
the initial separation between them, 
the mass of the proton and v its final velocity. 
is very far away, so the final electric potential will be 0J, and we have:
Answer:
Energy needed = 54.02 J
Explanation:
the Energy in an elastic spring from hookes law is given as
F= ke , therefore the energy (E) is
E = 
K = 19.5 N/cm
e = 1.39cm
E = 
x 19.5 x 1.39
E = 13.55 J
The energy to stretch the spring for 6.93cm is
E = x 19.5 x 6.93
E = 67.57 J
The more energy needed for the further stretch is
67.57 - 13.55
Energy needed = 54.02 J
