Read each question carefully and provide clear, concise answers. Show all your work where applicable. For multiple-choice questions, select the best answer.
The graph below shows the position of an object as a function of time. Analyze the graph and answer the following questions.
1. Describe the motion of the object between t = 0s and t = 1s.
2. What is the velocity of the object between t = 1s and t = 2s?
3. Calculate the average velocity of the object between t = 0s and t = 5s.
A student conducted an experiment to investigate the relationship between the applied force and the acceleration of a cart. The following data was collected:
Force (N): 2.0, 4.0, 6.0, 8.0, 10.0 Acceleration (m/s²): 0.5, 1.0, 1.5, 2.0, 2.5
4. What is the most appropriate conclusion the student can draw from this data?
Force is inversely proportional to acceleration.
Force is directly proportional to acceleration.
Acceleration increases exponentially with force.
There is no relationship between force and acceleration.
5. Based on the data, what is the approximate mass of the cart?
2.0 kg
4.0 kg
0.5 kg
5.0 kg
Consider a theoretical model for the decay of a radioactive isotope, given by the equation N(t) = N₀e^(-λt), where N(t) is the number of radioactive nuclei at time t, N₀ is the initial number of nuclei, and λ is the decay constant.
6. The term N₀ represents the of radioactive nuclei at time t = 0.
7. The decay constant λ is directly related to the of the radioactive isotope.
8. After one half-life, the number of radioactive nuclei remaining will be of the initial number.
Determine whether each statement is true or false based on principles of physics.

True
False
10. In a series circuit, the current is the same through all components.
