2 is neither bulbs since it’s only connected to positive.
3 is just bulb A since only bulb A is hooked up to a positive and negative
1. Decreases
To make something positive you remove electrons so it decreases
The "i" component of a vector is in the x-direction. Therefore, the x-component is 3 m/s.
Whenever an object is in projectile motion, that is, it has 2-dimensional motion in the x and y axis, the resultant force on the object is in the y-direction.
This is because once the object has been projected, or the ball has been kicked in this case, there is no longer a force being applied on it in the x-direction. The air resistance is also neglected so the ball's final velocity in the x-direction is equal to its initial velocity in the x-direction.
However, the force of gravity cannot be neglected and causes the ball to come downwards. Therefore, after the ball has been projected, the net force on the ball is downwards, due to gravity.
