Currently, many researchers are still working to find them.
Currently , its only theorized and they should be based on the quantum and particle theory
hope this helps
Explanation:
It is given that,
The angular acceleration of the basketball, 
Time taken, t = 3 seconds
We need to find the ball’s final angular velocity if the ball starts from rest. It can be calculated using definition of angular acceleration i.e.





So, the ball's final angular velocity is 30 rad/s. Hence, this is the required solution.
A charged atom is called a(n) ion. It can be negative charge or positive.
Answer:
176.4 m
Explanation:
U = 0, t = 6s, g = 9.8 m/s^2
Use second equation of motion
H = ut + 1/2 gt^2
H = 0 + 0.5 × 9.8 × 6 × 6
H = 176.4 m
It is the displacement from the point of dropping of object.
