Seema knows the mass of a basketball. What other information is needed to find the ball’s potential energy? the volume and heigh
2 answers:
Answer:
Acceleration due to gravity and the height the ball reaches
Explanation:
The potential energy of an object can be determined using its mass and the height of the ball it reaches. It is given by :
Where
m = mass of the ball
g = acceleration due to gravity
h = height reached by the ball
Hence, to find the ball’s potential energy she must know the "acceleration due to gravity and the height the ball reaches". Hence, the correct option is (c).

Solution :
a). B at the center :
Here, one of the current is in the clockwise direction and therefore, the other current must be in the clockwise direction in order to cancel out the effect of the magnetic field that is produced by the other.
Therefore, the answer is ANTICLOCKWISE or COUNTERCLOCKWISE
b). Also, the sum of the fields must be zero.
Therefore,
So,
A
Therefore, the current in the outer wire is 24.38 ampere.
