If an object's position remains constant as a function of time, it means that the object is not moving. Therefore, both its velocity and acceleration must be zero.
So the correct statement is: Acceleration and velocity are both zero.

In Reginald Rose's play "Twelve Angry Men," the 8th Juror is the character who initially votes "not guilty" and raises doubts about the defendant's guilt. Here are three points he brings up that create uncertainty regarding the defendant's culpability:
Lack of Concrete Evidence: The 8th Juror questions the reliability of the evidence presented. He points out that the murder weapon, a knife, could easily be found elsewhere and that the uniqueness of the knife was overstated. He posits that it could potentially belong to many people, which undermines the prosecution's argument.
Witness Testimonies: The 8th Juror scrutinizes the credibility of the eyewitnesses who testified against the defendant. He highlights inconsistencies in their accounts, such as the old man's ability to hear and see the events in the chaos of the moment. He raises doubts about whether they were truly in a position to have witnessed the crime as they claimed.
Motive and Background: The 8th Juror encourages the group to consider the defendant’s background and potential motive. He points out that the defendant had a troubled upbringing and a previous record of minor offenses, but he argues that this does not equate to guilt for the murder. He emphasizes the importance of not jumping to conclusions based on prejudices or assumptions about the defendant's character.
These points contribute to the 8th Juror's belief in the necessity of reasonable doubt, which is fundamental to the concept of justice in a trial.
Sure! Here’s a simplified and shorter rephrasing of the points:
Unclear Evidence: The 8th Juror questions the proof against the defendant. He says the knife used in the murder is common and could belong to many people.
Doubtful Witnesses: He looks closely at the eyewitnesses and points out that their stories don’t match and they might not have seen the crime clearly.
Defendant’s Background: The 8th Juror reminds everyone that the defendant had a tough life and a record of small crimes, but that doesn’t mean he’s guilty of murder.
These reasons help him show that there is reasonable doubt.
Here’s a revised version with even simpler language and shorter sentences:
Unclear Evidence: The 8th Juror questions the proof. He says the knife was common and could belong to anyone.
Doubtful Witnesses: He examines the witnesses. Their stories don’t match, and they might not have seen the crime well.
Defendant’s Background: The 8th Juror says the defendant had a hard life and some minor crimes, but that doesn’t mean he is guilty of murder.
These points show that there is doubt about the defendant’s guilt.
