The statement: Mass affects how fast an object falls is true.
Answer:
The time taken by the rotating object to speed up from 15.0 s to 33.3 rad/s is 5.30 seconds.
Explanation:
It is given that,
Initial angular speed of the object,
Final angular speed of the object,
Angular acceleration of the object,
Angular acceleration of an object is object is defined as the change in angular velocity per unit time. It is given by :
t = 5.30 seconds
So, the time taken by the rotating object to speed up from 15.0 s to 33.3 rad/s is 5.30 seconds. Hence, this is the required solution.
The answer to your question is in fact <u>True</u>
Why?
Sound waves can only travel through things like water, walls, and solids. so sound cannot travel through space because there is no matter for the vibrations of the sound to work in.
7A 8A maybe I’m not sure sorry if it’s wrong.
C.
1,0,-2
you solve by substitution
x=1
y=0
z= -2
