Answer:
A) is repelled by the sphere
Explanation:
- When a piece of plastic is rubbed with a wooden cloth, it sinks negatively
- Let it change Q. So it is now allowed to touch the neutral zone. Therefore, there is a difference in the surface capacity of the two bodies, so that charge transfer takes place
- Some of its negative charge is transferred to the metal sphere, now both the rod and the sphere are negatively charged and the same chargers as we know are repelled by each other.
- so correct answer is A) is repelled by sphere
Q=l^2 times R times t
Where Q - heat, I -current, R - resistance and t is time
If you increase I twice (and it's squared), than Q gonna went up 4 times (2 squared).

For counting x you use simple equation for the distance covered by the object when it moves with constant velocity:

that gives you 20m after 1st second, 40 m after 2nd second, 60 m after 3rd second and so on.
For counting y you have to use the equation for the distanced covered by the object moving with constantly accelerating velocity (symbols refering to vertical movement):

that gives you 5m after 1st second, 20m afters 2nd second, 45m after 3rd second and so on.
Add minus signs before y positions to receive graph presenting the movement of the ball.
So the points are: P1=[20,-5], P2=[40,-20], P3=[60,-45] and so on... Pn=[x,y].
