The freezing point constant means that the temperature depression when adding one mole of the solute. The mole number of the solute is 10.20/180=0.0567 mol. So the answer is 1.86*0.0567=0.105 ℃.
Answer: Option (B) is the correct answer.
Explanation:
When two circles are of same same then they are known as congruent circles.
Whereas a rectangle is a kind of parallelogram with all sides equal to 
.
Therefore, when 2 congruent circles and 1 rectangle combines then it results in the formation of a cylinder.
Thus, we can conclude that solid formed when 2 congruent circles and 1 rectangle combines will be a circle.
The Earth's core is the part of Earth in the middle of our planet. It has a solid inner coreand a liquid outer core.
I think the correct answer is proton since protons have a charge of +1 while electrons have a charge of -1. However, since beta particles are used to name a type of nuclear decay and can refer to either a positron or electron depending on the circumstances, your teacher might want you to put beta particle since positrons are basically electrons but that have a positive charge.
I hope this helps. Let me know if anything is unclear.
