MASTERING PHYSICS FREQUENT EXAM QUESTIONS AND ANSWERS LATEST 2023 FINAL Which of the following best describes how to calculate the average acceleration of any object? - ANSWER Average acceleration is always equal to the change in velocity of an object divided by the time interval. The figure shows the velocity versus time graph for a car driving on a straight road. Which of the following best describes the acceleration of the car? - ANSWER The acceleration of the car is positive...

Mastering Physics 2 Questions With Correct Answers and Diagramatic Expressions at some instant in time between t=1 and t=4 At what time(s) do the rockets have the same velocity? at time t=1 only at time t=4 only at times t=1 and t=4 at some instant in time between t=1 and t=4 at no time shown in the figure at times t=1 and t=4 At what time(s) do the rockets have the same x position? ANSWER: at time t=1 only at time t=4 only at times t=1 and t=4 at some instant in time betwee...

MASTERING PHYSICS QUESTIONS AND ANSWERS What is Newton's law of gravitation? - ANSWER Every body in the universe attracts every other body with a mutually attracting force. For two bodies, this force is directly proportional to the product of their masses and inversely proportional to the square of the distance separating them. What is the expression for a gravitational force? Assume that m1 and m2 are the masses, d is the distance between their centers, G is the universal constan...

MASTERING PHYSICS FREQUENT EXAM QUESTIONS AND ANSWERS Which part of the atom is positively charged and which part is negatively charged? - ANSWER The nucleus is positively charged and the electron cloud is negatively charged. How does the charge of one electron compared to that of another electron? How does it compare with the charge of a proton? How do the masses of protons and electrons compare? - ANSWER All electrons have the same charge. Electron charges equal and opposite t...

Mastering Physics QUESTIONS AND ANSWERS A plastic rod is rubbed with a fur. During the rubbing process, the rod acquires a negative charge. What type of charge does the fur acquire? - ANSWER The fur acquires a positive charge. A positively charged rod is brought close to one end of an uncharged metal rod but does not actually touch it. What type of charge does the end of the metal rod closest to the positively charged rod acquire? - ANSWER The end of the metal rod closest to the...
