Answer: A)
Explanation: when an electron is placed in a magnetic field, it experiences a force.
This force is given below as
F=qvB*sinθ
F = force experienced by charge.
q = magnitude of electronic charge
v = speed of electron
B= strength of magnetic field
θ = angle between magnetic field and velocity.
What defines the force exerted on the charge is the angle between the field and it velocity.
If magnetic field is parallel to velocity, then it means that θ=0° which means sin 0 = 0, which means
F = qvB * 0 = 0.
The charge being at rest has nothing to do with the angle between magnetic field strength and velocity.
Individuals have different traits because they are not twins so they should not be alike also because people have different genes witch would give them different traits. For example not every individual has blonde hair and blue eyes because they did not inherit those traits.
Answer:
C) seems to be the correct one
Each alpha particle emitted decreases the mass of the nucleus by 4 and decreases the atomic number by 2.
Also, each beta particle will increase the atomic number by 1.
So if C emits 5 alpha particles the atomic mass decreases by 20 and the atomic number decreases by 10. Then emission of 2 beta particles brings the atomic number up to minus 8.
So a total of 7 particles have been emitted and the number of alpha particles emitted exceeds the number of beta particles emitted.
Answer:
when work is done by an applied force, the objects energy will change. in this interactive, does the work cause a kinetic energy change or a potential energy change?
The work done cause the potential energy to change because the body was initially at rest before work done, it was after a force is applied that there is energy changes from potential to kinetic energy
