Which is true of a solute dissolved in a solvent? a)the solute raises the freezing point of the solvent. b) the solute raises the boiling point of the solvent. c)the solvent decreases the conductivity of the solute.

Hi,

The correct answer option is (B)The solute raises the boiling point of the solvent

Explanation:

Boiling point of a solvent is affected by the number of particles in a solution.Adding a solute to a solvent increases its boiling point because it lowers the vapor pressure of the solution.This is all about colligative properties where a decrease in vapor pressure will mean more heat needed to heat the solution to a boiling point.

All the best.

there is no correct list among the choices you've provided.

the list might look something like this:

-- baby human

-- piccolo

-- flute

-- soprano singer

-- trumpet

-- tenor singer

-- trombone

-- baritone singer

-- baritone horn

-- bass singer

-- tuba

since i had to make up the list myself, i made it easy on myself, and i didn't try to shuffle the string instruments and woodwinds into it too.

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
