Parabolic path
The net force on the ball is directed towards the center of the circle, providing the centripetal force required to keep the ball moving in a circular path. This force is perpendicular to the velocity of the ball at any given moment.
that depends on 3 factors, how big is the circle, how fast is the train, and how high is the ball thrown also it is to be considered that u are assuming the natural (actual) conditions like the air thrust is present or hypothetical conditions that there is no air thrust. Under all ideal conditions i.e. no air thrust etc. the ball will move tangentially to the path of the circle the train is traversing.
If the bus is moving at a constant horizontal velocity relative to you and the ball, there is no horizontal acceleration and therefore no horizontal force. The only force acting on the ball is gravity, which is vertical, so the ball will just fall straight down next to you.
Yes, a moving body is an example of an object that moves along a straight path if its motion is in a single direction without deviating from that path. For instance, a car moving in a straight line on a road or a ball rolling in a straight line on a flat surface are examples of motion along a straight path.
The centripetal force is what causes a ball to accelerate around a pole. It is directed towards the center of the circular path and keeps the ball moving in a curved trajectory.

Relative to the person in the bus, the ball goes in a vertical line. To a person outside the moving bus it would go in a parabolic path.
If the bus is moving at a constant horizontal velocity relative to you and the ball, there is no horizontal acceleration and therefore no horizontal force. The only force acting on the ball is gravity, which is vertical, so the ball will just fall straight down next to you.
Yes. It is correct to say that the 7 train transfer to the PATH train.
Yes. It is true to say that the 7 train transfers to the PATH train.

A ball that is thrown horizontally will stay in the same path because there are no horizontal forces acting on it to change its motion. In the absence of air resistance and other external forces, the ball will continue moving at a constant horizontal speed due to its inertia.
Picture a ball on a string being whirled about the head of an experimenter. If the string breaks, the centripetal force disappears. The ball leaves on a tangent path form its (previous) circular path. Yes, it's that simple. The string provided centripetal force, by virtue of its tensile strength, to the ball to keep that ball moving in a circle. When the string broke, there was no force left to accelerate the ball "in" and keep it moving in an arc.
This is what we call relativity. As we being on the platform observe one sitting in a train at rest throwing a ball vertically upward and catch it back as it comes downward, we see the ball is going along a straight line. Now the same phenomenon is observed by us when the train is at uniform speed. We still stand on the platform which is at rest. But the man in the train is moving at uniform speed. Now for him he experiences the same straight line movement of the ball up and down. But for us being on the platform the ball seems going along a parabolic path. This is what we call relativity. Our frame of reference is the platform at rest. But the man in the train has his frame of reference moving at uniform speed.
The magnitude of the tension in the string at the bottom of the circle is equal to the sum of the gravitational force acting on the ball and the centripetal force required to keep the ball moving in a circular path.
