To develop this problem it is necessary to apply the concepts related to electromagnetic energy and Broglie's hypothesis.
By definition we know that the electrical energy of a proton can be expressed as
E = qV
Where,
q = Charge of proton
V = Voltage
Replacing with our values
E = qV
It is necessary to add the two potentials
From Broglie's hypothesis we know that the wavelength is given by
Where,
h = Planck's constant
p = Momentum
The momentum of a particle can be expressed in terms of energy, that is,
Where,
m = mass
E = Energy (potential or kinetic)
Therefore replacing this value at lambda,
All metals are good conductors.
Hope that helped you.
Answer: Kinetic Energy is the energy of mass in motion. In a rescue mission, kinetic energy is the most used energy to carry out the rescue operation successfully. ... The machineries involved in the rescue mission like helicopters, submarines, lifeboats are all examples of kinetic energy.
In the given question, there are several information's of immense importance. Using those given information's, it is easy to get to the required result. It is given that the mass of the box Ellie is pushing is 7 kg with a force of 25 newtons. the force of friction effecting the acceleration is 2.6 Newton.
We already know that
Force = mass * Acceleration
We also know that
Force = Force applied - Force of friction
= (25 - 2.6) Newton
= 22.4 Newton.
Now putting the value of force in the equation, we get
Force = Mass * Acceleration
22.4 = 7 * Acceleration.
Acceleration = 22.4/7
= 3.2 m/s^2
So the value of acceleration is 3.2 m/s^2
