Explanation:
An atom consists of three subatomic particles which are protons, neutrons and electrons.
Protons and neutrons are placed inside the nucleus whereas electrons revolve around the nucleus.
Protons are positively charged particles and neutrons have no charge. On the other hand, electrons are negatively charged species.
Thus, we can conclude that charge of the nucleus is positive as neutrons have no charge so the charge of protons bring positive charge on nucleus of atom.
Answer:
Muscular dystrophy (MD) is a group of inherited diseases in which the muscles that control movement (called voluntary muscles) progressively weaken. In some forms of this disease, the heart and other organs are also affected. There are nine major forms of muscular dystrophy: Myotonic.
In most cases, muscular dystrophy (MD) runs in families. It usually develops after inheriting a faulty gene from one or both parents. MD is caused by mutations (alterations) in the genes responsible for healthy muscle structure and function.

All of the above, work is a measurement of energy transfer, in Joules.
Potential energy = Joules
Kinetic energy = Joules
The key thing here is that anything having to do with just energy or energy transfer is measured in joules.
The units of pressure are called derived units because it is derived from base unit, which is distance and a derived unit which is force. Force is derived from acceleration, a derived unit as well, and mass, a base unit; which makes it a derived unit.
