To solve this problem it is necessary to apply the concepts related to the kinematic equations of angular motion.
By definition, acceleration can be expressed as the change in angular velocity squared over a given period of distance traveled.
where,
Angular velocity
Angular displacement.
In turn, as a function of time, we can represent it as,
For our case we have to,
PART A) In the case of angular acceleration we have to,
PART B) Through the definition of angular acceleration as a function of time we can calculate it,
Temperate I'm not sure, cuz polar is like freeze, and tropical is hot
Answer:
The answer is letter C, The energy of the supersaturated liquid is converted to heat as the compound crystallizes.
Explanation:
"Hand warmers" are very essential when the cold season comes. It provides warmth to the hands, especially when going outdoors. There are different kinds of hand warmers, such as the<em> "reusable hand warmer." </em>In contrast to air-activated hand warmers, the reusable hand warmers contain sodium acetate (not iron).
Sodium acetate is a "supersaturated liquid." This means that is has more substances dissolved in it. So, when this crystallizes, heat is released. Remember that crystallization is considered an "exothermic process." This means that the process releases energy (in this case, through "heat").
Thus, this explains the answer, letter C.
