An object is placed at the center of curvature of a concave mirror. Which of the following is true about the image? A. It is real and inverted B. It is virtual and inverted C. It is real and upright D. It is virtual and upright Correct Answer-A One could solve this question with a ray diagram, but be wary about using these on Test Day. it is easy to make small mistakes. So solve the question using the sign convention. If the object is at the center of curvature, its distance is 2f. We can p...

What does the term force describe? Correct Answer-an outside influence on an object. What is a frame of reference? Correct Answer-means that if the placement of one object is known, it is easier to locate another object with respect to the position of the original object. What is speed a measurement of? Correct Answer-an objects movement or change in position (x), over a change in time (t). What is the measurement of speed with direction called? Correct Answer-velocity What is the eq...

What is the mechanical work done by the cantilever when the extension increases from 10 nm to 15 nm? 2.00 × 10-22 J 4.70 × 10-20 J 2.50 × 10-19 J 5.00 × 10-18 J correct answers This question requires you to apply the graphical method of calculating the work done by a variable force, namely the elastic force, W = ksx2/2. Mechanical work by an elastic force is W = ksx2/2 = Fx/2. Graphically, it is the area under the force-extension graph between the corresponding data points. From Figure...
