Answer:
si la. carga es positiva experimenta una fuerza en el sentido del campo
en cambio si la carga es negativa,experimenta una fuerza en sentido contrario al campo
<span>Angular distance moved = 220 rad = {35(2π) ≈ 220 rad}
Max angular speed = 18 rad/s
Final angular speed = 0 rad/s
Avg angular speed = 9 rad/s {assuming a CONSTANT de-celeration of wheel}
Time to stop = 220/9 = 24.4 s ANS</span>

3. Behind the spoon
Explanation:
Answer:
Ethan's tangential speed is twice as Rebecca's.
Explanation:
Let be the distance from the center of the platform to Rebecca's horse, Rebecca's tangential speed, the Ethan's tangential speed and the merry-go-round angular speed. The distance from the center of the platform to Ethan's horse is . The angular speed is related to the tangential speed by the equation:
Since the angular speed is the same for Ethan and Rebecca, we have that:
Now, solving for we get:
It means that Ethan's tangential speed is twice as Rebecca's.
