Becuase the frisbee is spinning at a CONSTANT RATE, the radial acceleration is zero. when radial acceleration is zero, tangential acceleration is zero too, according to the equation Acceleration (tangential) = Acceleration (radial) times radius
They bounce off just like sun rays when they heat the atmosphere they bounce off reflection
Answer:
Eye function renders you the sense of sight. They convert light into electrical signals. Afterwards, the brain deciphers these electrical signals into images. Properly working healthy eyes are able to perform the following functions.
Explanation:
Answer:
Time= t= 1.67 secs
Explanation:
Time= t=?= 1.67 secs
Initial Velocity= Vi = 2m/s
Final Velocity= Vf = 4m/s
Average Acceleration= av= Vf-Vi/t
Putting the values : 1.2m/s²= 4-2/t
Rearranging: t= 2/1.2= 1.67 secs
<span>The question is asking us what is BEST to say about a runner who is running at a constant velocity? A constant velocity (=speed) means that they are not getting faster or slower - they are running exactly as fast all the time. This meanst that their speed does not change, so their change of speed is equal to 0. A change of speed is called acceleration so their C. Their acceleration is zero. - C is the correct answer. </span>
