Given:
F_gravity = 10 N
F_tension = 25 N
Let's find the net centripetal force exterted on the ball.
Apply the formula:

From the given figure, the force acting towards the circular path will be positive, while the force which points directly away from the center is negative.
Hence, the tensional force is positive while the gravitational force is negative.
Thus, we have:

Therefore, the net centripetal force exterted on the ball is 15 N.
ANSWER:
15 N

B is a chemical property
Reference what are physical properties
And what are chemical properties
Under certain conditions it can release a gas is the key words letting you know this is a chemical property
When the iron bar is placed within the coils of a solenoid it then becomes a magnet.
Answer:
There cannot be a force without motion and if there is no motion, then there is no force acting.
Explanation:
A force is a vector that causes an object with mass to accelerate.
