Two Experiments Are Performed

question 108

Multiple Choice

Two experiments are performed. In (A) , an 18.0 N force pushes horizontally on a 2.00 kg block that then pushes on a 4.00 kg block. In (B) , an 18.0 N force pushes on a 4.00 kg block that then pushes on a 2.00 kg block. Which statement is correct?

• A) The acceleration is 3.00 m/s² in both (A) and (B).
• B) The acceleration is 4.50 m/s² in both (A) and (B).
• C) The acceleration is 6.00 m/s² in both (A) and (B).
• D) The acceleration is 9.00 m/s² in both (A) and (B).
• E) The 2.00 kg block has a 9.00 m/s² acceleration. The 4.00 kg block has a 4.50 m/s² acceleration.

Definitions:

Radioactivity

The process by which unstable atomic nuclei lose energy by emitting radiation, including alpha particles, beta particles, and gamma rays.

Poisson Distribution

A probability distribution that expresses the probability of a given number of events occurring in a fixed interval of time or space when these events occur with a known constant mean rate and independently of the time since the last event.

Poisson Random Variable

Reflects the number of times a specified event occurs within a fixed interval, assuming events occur independently and at a constant rate.

Poisson Probabilities

The probability distribution that measures the probability of a given number of events happening in a fixed interval of time or space, assuming these events occur with a known constant mean rate and independently of the time since the last event.
