Answer:
The best-known power of the Supreme Court is judicial review, or the ability of the Court to declare a Legislative or Executive act in violation of the Constitution, is not found within the text of the Constitution itself. The Court established this doctrine in the case of Marbury v. Madison (1803).
Answer: 0.817A
Explanation:
Assuming , that one coulomb per second of negative charge alone flow through a conductor and no positive charges flow. I.e Q=It
It means a current of one A flow in the opposite direction.
This is similar to one coulomb per second of positive charge flowing through and there is no negative charge,
In addition, the one coulomb per second of positive charge flows. This is flowing in the current direction of the previous one. Then, the total current is 2 A. Since 2 coulomb of positive charges flow through one due to real positive charge and another due to the negative charge flowing in opposite direction.The charges cannot cancel each other, because even before the current flow the conductor was neutral.
According to this, the current in the given problem is
[2.7 + 2.4] x 10 ^ 18 * 1.602 x 10^ [-19] C/s
= 0.817 A
To solve this problem it is necessary to apply Newton's second law with the peculiarity that the expression given for velocity must be expressed in terms of the rate of change of velocity and time.
Mathematically this is,
F= ma
Where,
m = mass
= Change in velocity
t = Time
Since the time interval occurs when the speed hits - in the downward direction - until it bounces - in the upward direction - we will have that the change in speed is given by
The rest of our values are given as:
m = 0.26s
t = 0.44kg
Finally replacing we will have to
Therefore the final average force of the floor on the ball is 13.53N
