The temperature and the solubility of sugar at that temperature
Explanation:
The amount of substance which can be dissolved in the solvent depends on the temperature.
As the temperature increases, more substance can be dissolved.
A solution is saturated if any more of the solute cannot be dissolved in the solution at the given temperature
Hence we need to know the temperature and also the amount of substance which can be dissolved(solubility) at the same temperature
a) the statement given in option A is correct
b) molar mass has no correlation with the substance's solubility and hence option b is not correct
c) The percent by volume of the solution is not needed to find if the solution is saturated and hence option c is not correct
The change in electric potential energy of the ion is equal to the charge multiplied by the voltage difference:
where the charge q of the na+ ion is equal to one positive charge, so it's equal to the proton charge:
, and Vf and Vi are the final and initial voltages.
Substituting the numbers, we find:
Answer:
126.99115 g
Explanation:
50 g at 90 cm
Stick balances at 61.3 cm
x = Distance of the third 0.6 kg mass
Meter stick hanging at 50 cm
Torque about the support point is given by (torque is conserved)
The mass of the meter stick is 126.99115 g
Answer:
Plasma
Explanation:
For a fusion reaction to take place, there must be conditions in which the particles have extreme thermal kinetic energies, in this way the collisions that cause the nuclear fusion are generated. Therefore, it is necessary to reach very high temperatures, in which the state of matter will necessarily be plasma.
The sentence can be completed as follows:
<span>The motion of an object moving with uniform circular motion is always tangential to the circle, so the speed of an object moving in a circle is known as tangential speed.
The object moves by uniform circular motion due to the presence of a force (called centripetal force) pointing toward the center of the circle. Due to the presence of this force, the object experiences an acceleration (called centripetal acceleration) that makes the object turning in a circle. This centripetal acceleration changes only the direction of the velocity of the object, not its magnitude, which is called tangential speed and it is constant.</span>
