Answer:
True
Explanation:
Because everything usually has chemicals
Plz say it's false if i gave out the wrong answer
Vaporization - Th<span>e amount of heat needed to convert unit mass of a liquid into vapor form without a change in temperature is called heat of vaporization. For water t</span><span><span>he heat of vaporization is 2260 Joules / gram</span> at its normal boiling point .</span>
Given:
initial angular speed, 
= 21.5 rad/s
final angular speed, 
= 28.0 rad/s
time, t = 3.50 s
Solution:
Angular acceleration can be defined as the time rate of change of angular velocity and is given by:
Now, putting the given values in the above formula:
Therefore, angular acceleration is:
To calculate the velocity relative to car A, you have to add the opposite of the velocity of car A to car B.
the velocity of car B relative to car A:
(let east and north directions be positive)
v = v (car B) - v(car A)
v(east-west direction) = -120 * cos 30° - 110
v(north - south direction) = -120 * sin 30° - 0
