Answer : The correct option is, (A) dilute the solution
Explanation :
Saturated solution : It is a solution in which the maximum concentration of the solute dissolved in the solvent. The additional amount of the solute will not be dissolved in saturated solution.
Unsaturated solution : It is a solution in which the minimum concentration of the solute dissolved in the solvent. The additional amount of the solute will dissolved in unsaturated solution.
As per given question, when the solution is over-saturated with the solute then to decrease the over-saturation we will dilute the solution. That means more amount of solvent will be added to the over-saturated solution.
1) The coefficient of friction of the surface
2) The weight of that objects
Answer: 5,728.5 years
Explanation:
By measuring the current ratio of daughter to parent, that is (Dt/Pt) one can deduce the age of any sample. The assumption is that there is no daughter atom present at time,t=0 and that the daughter atoms are due to the parent decay(where none has been lost).
Lamda= ln 2÷ half life,t(1/2)
Lamda= ln2= 0.693/5730 years
Lamda=1.21 × 10^-4
Using the formula below;
Age,t= 1/lamda× (ln {1+ Dt/Pt})------------------------------------------------------------------------------------(1)
Slotting our values into equation (1) above.
Age,t= 1/lamda(ln[1+1/1])
Age,t= 1/1.2×10^-4(ln 1+1)
Age,t= 1/1.21×10^-4(ln 2)
Age,t= ln 2/ 1.21×10^-4
Age, t= 5,728.5 years.
HERE'S YOUR ANSWER
Explanation:
Antimatter is a material composed of so-called antiparticles. It is believed that every particle we know of has an antimatter companion that is virtually identical to itself, but with the opposite charge. For example, an electron has a negative charge.
Answer:
And now we can find the final distance on the x axis using the formula:
The velocity on x not changes and is the same plane spped 
, if we replace we got:
Explanation:
For this case we have a illustration for the problem in the figure attached.
We need to find how far short of the target should be the plane, we have the following info given:
How far short of the target should it drop the package?
First we can find the total time in order to reach the groung using the following kinematic formula:
And replacing we have:
And solving for t we got:
And now we can find the final distance on the x axis using the formula:
The velocity on x not changes and is the same plane spped , if we replace we got:
