<span>The correct option is A. There are three basic type of solutions, these are: unsaturated, saturated and super saturated solution. An unsaturated solution is a solution that has the capacity to hold more solute at a particular temprature, it is a solutin that is not yet saturated with the solute [particles dissolve in it].</span>
Answer:
they have the same mass
Explanation:
The force applied by the field is a function of the charge and velocity, so the acceleration experienced by a particle will be dependent upon its mass. Particles in orbits with the same radius are exhibiting the same acceleration, so must have the same mass.
Gravity decreases with the square of the distance, so the new force is (20)/(2*2) = 5N.
Answer:
The peak value of the electric field is 489.64 V/m
Explanation:
Given;
power of the laser, P = 1.0 mW = 1 x 10⁻³ W
Radius of the beam, R = 1.0 mm = 1 x 10⁻³ m
Area of the beam = πr² = π(1 x 10⁻³ )² = 3.142 x 10⁻⁶ m²
The average intensity of the light = P / A
The average intensity of the light = ( 1 x 10⁻³) / (3.142 x 10⁻⁶)
The average intensity of the light = 318.27 W/m²
The peak value of the electric field is given by;

Therefore, the peak value of the electric field is 489.64 V/m.
Galileo Galilei was the first scientist to perform experiments in order to test his ideas. He was also the first astronomer to systematically observe the skies with a telescope.
