Answer:
A plasma.
Step-by-step explanation:
A plasma is a hot, ionized gas in which the atoms have lost one or more of their electrons.
Thus, the plasma consists gaseous ions as well as the electrons that were stripped from them.
The Sun's high temperatures strip the electrons from its hydrogen and helium atoms, so the Sun is essentially a giant ball of plasma.
Answer:
To calculate the volume of the approximately 0.014 M copper (II) sulfate solution needed to prepare 100.00 milliliters of a 0.00028 M copper (II) sulfate solution, you can use the formula:
(Volume 1)(Concentration 1) = (Volume 2)(Concentration 2)
So, rearranging the formula, you can solve for Volume 1 (the volume of the 0.014 M solution):
Volume 1 = (Volume 2)(Concentration 2) / Concentration 1
Plugging in the values:
Volume 1 = (100.00 milliliters)(0.00028 M) / 0.014 M
Volume 1 ≈ 2.00 milliliters
Approximately 2.00 milliliters of the approximately 0.014 M copper (II) sulfate solution are needed to prepare 100.00 milliliters of a 0.00028 M copper (II) sulfate solution.

C- period of rotation
D-period of revolution
The answer is -30 N
The explanation:
- to make the box move. so,the horizontal force must be greater than the frictional force.
-and when the horizontal force applied is 30 N. So, the box will remain stationary if the frictional force is equal in magnitude but opposite in direction to the horizontal force. means frictional force = -30 N
This is also being indicate that vertical force due to gravity is equivalent to the normal force when gravity force = 8 N and normal force =8 , meaning the box does not move vertically.
