Answer:
Unsaturated Solution: Less amount of salt in water, clear solution, no precipitation. Saturated Solution: The maximum amount of salt is dissolved in water, Colour of the solution slightly changes, but no precipitation. Supersaturated Solution: More salt is dissolved in water, Cloudy solution, precipitation is visible.
Answer:
becouse most of nuclear elements are heave
Explanation:
X2 = 60
/ 2 / 2
x = 30
Plus or minus square root 60
Frequency: 
Explanation:
The force experienced by an electron in a magnetic field is
where
is the electron charge
v is the speed of the electron
B is the strength of the magnetic field
Since the force is perpendicular to the direction of motion of the electron, the force acts as centripetal force, so we can write:
where
r is the radius of the orbit
is the mass of the electron
Re-arranging the equation,
(1)
We also know that in a circular motion, the speed is equal to the ratio between circumference of the orbit and orbital period (T):
Substituting into (1),
We also know that 1/T is equal to the frequency f, so
In this problem,
Therefore, the frequency of the electrons is
potential energy because it has the ability to do work
Explanation:
A rock resting high in a cliff is an example of potential energy because it has the ability to do work. This form of energy is called potential energy.
- Energy is defined as the ability to do work. To do work, force must applied using energy to move a body through a particular distance.
- A body at rest is not doing any work. This is the case with potential energy of the body on a high cliff.
- At the state of rest, it is not doing any work.
- The potential energy of this body expresses the ability of such body to do work.
