What does the symbol "E3" represent? ...?
2 answers:
Answer:
E₃ = energy in third energy level.
Explanation:
The energy of an electron is third orbit is given by :
Where
Z is the atomic number
n is principal quantum number and n = 1,2,3....
i.e. the energy of an electron is inversely proportional to the principal quantum number.
E₁,E₂,E₃.......... shows the energy of an electron in first, second and third energy level respectively.

The initial kinetic energy of the car is
Then, the velocity of the car is decreased by half:
so, the new kinetic energy is
So, the new kinetic energy is 1/4 of the initial kinetic energy of the car. Numerically:

When the ball starts its motion from the ground, its potential energy is zero, so all its mechanical energy is kinetic energy of the motion:
where m is the ball's mass and v its initial velocity, 20 m/s.
When the ball reaches its maximum height, h, its velocity is zero, so its mechanical energy is just gravitational potential energy:
for the law of conservation of energy, the initial mechanical energy must be equal to the final mechanical energy, so we have
From which we find the maximum height of the ball:
Therefore, the answer is yes, the ball will reach the top of the tree.

The resulting change in momentum of the system will be +18.6 Ns. The momentum is conserved.
According to the law of conservation of momentum, the momentum of the body before the collision is always equal to the momentum of the body after the collision.
The given data in the problem is;
m is the mass =6.0 kg
t is the time interval=2 second
From Newton's second law;
From the graph;
The change in the momentum is;
Hence, the resulting change in momentum of the system will be +18.6 Ns.
