Answer:
It has direction and size.
Explanation:
The way I learned it was that vectors have direction and Magnitude. Magnitude is just the length of the vector. So you are right.
I don't know if this is multiple choice but if it isn't I can name of few.

Answer: kg= 0.37
Explanation:
Use the molality formula.
M= m/kg
Answer
is: 325.5 mL of the stock solution.
c₁(AgNO₃)
= 0.675 M.
<span>
V</span>₂(AgNO₃) = 0.879 L.<span>
c</span>₂(AgNO₃) = 0.250 M.<span>
V</span>₁(AgNO₃) = ?<span>
c</span>₁ -
original concentration of the solution, before it gets diluted.<span>
c</span>₂
- final concentration of the solution, after dilution.<span>
V</span>₁
- <span>volume to
be diluted.
V</span>₂ - <span>final volume after
dilution.
c</span>₁ · V₁ = c₂
· V₂.<span>
V</span>₁(AgNO₃) = c₂ · V₂ ÷ c₁.<span>
V</span>₁(AgNO₃) = 0.250 M · 0.879 L ÷ 0.675 M.<span>
V</span>₁(AgNO₃) = 0.325 L · 1000 mL = 325 mL.
Answer : The final temperature will be
Explanation :
In this problem we assumed that heat given by the hot body is equal to the heat taken by the cold body.
where,
= specific heat of ice =
= specific heat of water =
= mass of ice = 15.0 g
= mass of water = 150 g
= final temperature = ?
= initial temperature of ice =
= initial temperature of water =
Now put all the given values in the above formula, we get
Therefore, the final temperature will be
