Given that,
Mass of a baseball, m = 0.2 kg
Initial speed of a baseball, u = 30 m/s
Force produced by a bat, F = 2000 N
Final speed of a baseball, v = -50 (negative for opposite direction)
To find,
For how long was the ball in contact with the bat?
Solution,
Let for t seconds the ball is in contact with the bat. The net force acting on the ball is given by :
So, the ball is contact with the bat for 8 ms.
B. It has membrane-bound organelles.
This is the most logical choice. For example, rocks can be found in water AND possess uneven shapes.
Answer:
The solved problems are in the photos. Hope it helps.
The cathode and anode are hooked up to an electrical circuit The chemical reactions in the battery causes a build up of electrons at the anode. This results in an electrical difference between the anode and the cathode. Hope this helps :)
