Answer:
(a) 120 eV
(b) 12.840 keV
(c) 0.466%
Solution:
As per the question:
The potential difference between the dees, V = 120 V
No. of passes, n = 107
Now,
(a) The potential energy can be given as 'qV' but by the principle of conservation of energy, this energy with each pass is converted into the kinetic energy of the particle which is given as 120 eV
Thus
The increase in Kinetic energy, 
(b) Kinetic energy on completion of 107 passes is given by:
(c) The velocity of the particle can be calculated from its kinetic energy:
Thus
Thus radius can be given as:
where
B = Magnetic field
= mass of proton
Therefore, we can write that:
Thus the percentage increase in radius from n = 107 to n = 108 is given by:
= 0.466 %
Answer:
86.4 N downward
Explanation:
Force: This can be defined as the product of mass and acceleration of a body.
The S.I unit of Force is Newton(N).
The Expression of force is given as,
F = ma ................ Equation 1
Where F = force of the parachute harness, m = mass of the skydiver, a = acceleration of the skydiver.
Given: m = 72 kg, a = 1.2 m/s²
Substitute into equation 1
F = 72(1.2)
F = 86.4 N down ward.
Hence the force on the parachute harness = 86.4 N downward
Answer:
Elastic potential energy is stored when materials stretch or compress. Examples of it include springs, rubber bands, and slingshots.
Explanation:
There are many forms of energy, but they can all be put into two categories: kinetic and potential. Kinetic energy is motion––of waves, electrons, atoms, molecules, substances, and objects. Potential energy is stored energy and the energy of position––gravitational energy
