Beta particles ARE electrons.
Also, in one of the great coincidences of Physics, electrons ARE beta particles.
Answer:
-320 μJ.
Explanation:
Consider a point with an electrical charge of . Assume that is the electrical potential at the position of that charge. The electrical potential of that point charge will be equal to:
.
Keep in mind that since both and might not be positive, the size of the electrical potential energy might not be positive, either.
For this point charge,
- ; (that's -8.0 microjoules, which equals to )
- .
Hence its electrical potential energy:
.
Why is this value negative? The electrical potential energy of a charge is equal to the work needed to bring that charge from infinitely far away all the way to its current position. Also, negative charges are attracted towards regions of high electrical potential. Bringing this negative charge to the origin will not require any external work. Instead, this process will release 320 μJ of energy. As a result, the electrical potential energy is a negative value.
Answer:
The word hot dog means the sausage that you buy squeezed in a plastic package the same sausage heated and served in a long split roll. When it's served in the roll, it's also a sandwich. ... Hence, a hot dog is a sandwich when served i roll.
