Answer:
Mechanical energy, is a sum of the kinetic energy, or energy of motion, and the potential energy, or energy stored in a system by reason of the position of its parts. Mechanical energy is constant in a system that has only gravitational forces or in an otherwise idealized system—that is, one lacking dissipative forces, such as friction and air resistance, or one in which such forces can be reasonably neglected.
Explanation:
Explanation:
Unbalanced forces are when 2 forces dont counteract each other since they are not equal and opposite. An example is drawing a person running forward with a force or 50N and air resistance pushing them back with a force of 20N. There would be a resultant" force of 30N in the direction they are running.
Answer:
li
Explanation:
Li has the greatest ionization
The first transistor made of gold, plastic and germanium was about the size of adult's fingernail.
Option C
<u>Explanation:</u>
The first transistor made of gold, plastic and germanium was invented in Bell laboratories. It is termed as point contact transistor. As it is made like a pointed arrow with both the sides covered with layer of gold foil. The germanium is used at the tip, just like the base and the gold foil ends as collector and emitter.
The size of this transistor is about the size of adult's fingernail. It is very small in size and it was one of its kind. Due to this small size and the working capacity by the point contact, it is termed as point contact transistor.
Answer:
it's option 2 : the medium increases in temperature while remaining in the same phase
