Answer:
apply to the breaks gently
Explanation:
Electrical energy is your answer.
Answer:
the period T of whole motion should be twice the value for half at he bottom so T is 0.2sec.
w is angular frequency
formula:2π/T
now k is spring constant
F/R-->mw²
putting values:70*(2π/0.2)²
=4.9x10⁶
so we can say that SHM is not affected by the amplitude of the bounce.
Answer:
True.
Explanation:
Adding a non - volatile solute to solvent, decreases the tendency for water molecules to evaporate into gas phase i.e these non - volatile solute particles obstruct or reduce the rate of evaporation. Few water molecules in the vapour.
Therefore, Adding a nonvolatile solute to a solution decreases the vapor pressure of the solution while
Vapor pressure is a measurement of the likelihood of the molecules of a pure solvent to change from the liquid to the vapor phase.
Using Raoult's Law:
Psol = Xsolv * P°solv
where:
Psol = the vapor pressure of the solvent above the solution,
Xsolv = the mole fraction of the solvent in the solution, and
P°solv = the vapor pressure of the pure solvent.
Answer:
The size and separation of the plates.
Explanation:
We know that the capacitance of a parallel-plate capacitor is given by :
Where
A is the area of cross section of the plate
d is the separation between the plates
It is clear that the capacitance of a parallel-plate capacitor is directly proportional to the area of plate and inversely proportional to the separation between the plates. So, the capacitance of a parallel-plate capacitor can be determined by the the size and separation of the plates. Hence, the correct option is (A).
