1.) what requirements do the circuit courts have that the supreme court doesn't have?

2) certiorari is usually only granted for worked what kinds of cases?

The answers are:

1. Courts decide what really happened and what should be done about it.  They decide whether a person committed or not a crime, and which punishment should be applied. They also provide mediation to decide private dispute, when people cannot work it out by themselves.

The supreme Court is the highest court in the United States.

2. At least four of the justices have determined that the circumstances described in the petition are sufficient warrant review by the Court.

Explanation:

1. The Us Constitution authorized Congress to pass laws establishing a system of lower Courts. There are 94 federal Courts  and 13 Courts of appeal below the Supreme Court. Courts decide what really happened and what should be done about it.  They decide whether a person committed a crime or not, and which punishment should be applied. They also provide mediation to decide private dispute, when people cannot solve by themselves. Depending on the criminal issue, some cases end up in Federal Courts and some end up in State Courts.

The Appellate Court's task is to determine whether or not the law was applied correctly in the trial court. Appeals court consist of three judges and do not use a jury. Federal and State Courts use a jury and the Supreme Court consist  of the Chief Justice of the United States, eight Associate Justice, the Court Counsel, among others.

2. Granting a writ of certiorari means merely that at least four of the justices have determined that the circumstances described in the petition are sufficient warrant review by the court.

As we can see here the lever has two forces at two ends

1. 300 N

2. 200 N

now we need to find the Torque on the lever about the fulcrum

so we will have

1. clockwise torque due to force at right end is

2. counterclockwise torque due to force at left end

so as per above calculations we can see that net torque on the lever is clockwise as it has more torque in clockwise direction

so it will rotate clockwise
