option E
Explanation:
given,
angular speed of bicycle tire ()= 3.80 rad/s
time period = 2.35 s
tire stops and spun in opposite direction with angular velocity = 3.80 rad/s
average angular acceleration
initial angular speed = ω₀ = - 3.80 rad/s
final angular speed = ω₁ = 3.80 rad/s
change in angular velocity
average angular acceleration
approximately equal to 3.4 rad/s²
the correct answer is option E
Answer:
mantle convection is the very slow creeping motion of earths solid silicate mantle caused by convection currents carrying heat from the interior to the planet's surface.
The story that fits the graph is; he elevator moves up, is stationary for a while, then moves down at a slower rate.
<h3>What is a position time graph?</h3>
The term position time graph shows us how the position of the object is changing with time. The position in this case has to do with the exact point in space where the object can be found. We have here an elevator that could be found at various points.
We now have to turn to the graph and see how the graph can be able to give a description of the motion of the elevator. If we look at the position time graph, it tends to move up and then remain at a point for some time before it moves down.
Based on the analysis that we have made above, we can now look out for any of the stories that fits the description that we have just made here.

Answer:
C. Blueshift
"If a star is moving towards the earth, its light is shifted to higher frequencies on the color spectrum (towards the green/blue/violet/ultraviolet/x-ray/gamma-ray end of the spectrum). A higher frequency shift is called a "blue shift"
