As we define the ground as the origin, the position of the rock is _____ and the velocity of the rock is _____, 1.20 Which of the following motions could be described by the motion diagram of figure 1.20? Vectors parallel to the positive x axis have an angle of 0 . What is the javelines kinetic energy at this point? STT 2.6 A cyclist is at rest at a traffic light. D -30 m/s B Increase TC If a scallop wishes to remain stationary, hovering a fixed distance above the ocean floor, it must eject water _____ so that the thrust force on the scallop is ____ a.5 s SCALE: 1 cm = 5 m. When added together in this different order, these same three vectors still produce a resultant with the same magnitude and direction as before (20. m, 312 degrees). A norm is a way to measure the size of a vector, a matrix, or a tensor. B the car exerts a larger force on the truck than the truck exerts on the car 12.32 Suppose you do a calorimetry experiment to measure the specific heat of a penny. d .5 hz. B F Q on H = F H on Q> F P on Q = F Q on P C they have the same number of atoms, StT 12.2 a sample of ideal gas law is in a sealed container. B 240 J What are (a) the magnitude and (b) the direction of vec a + vec b ? b. 4.21 A block has an acceleration a when pulled by a string. As the engine fires, it uses fuel, so it is much lighter at the end of the run than at the end of the run than at the start. (c) Draw a vector diagram for each combination. Each of the waves travel the same distance. B infrared has a shorter wavelength and higher frequency than ultraviolet B. Which vector best represents What is the angle between the net displacement vectors for the two birds? The following diagram shows how to find the magnitude of a 3D Vector. Which of the graphs is the correct history graph? C 21 S Express your answer to three significant figures and include the appropriate units. D it depends on how hard dave pushes Thomas, 4.29 Figure 4.29 shows block A sitting on top of block B. You left your house to visit a friend. C 7.5m B 4.0 M Later, when the air has warmed up to 25 degrees Celsius, the frequency is ASK AN EXPERT. STT 1.4 Jane starts from her house to take a stroll in her neighborhood. How many seconds after the light turns green does he reach his cruising speed of 6.0 M/S^2? Which is a dust particle settling to the floor at constant speed, which is a ball dropped from the roof of a building and which is a descending rocket slowing to make a soft landing on mars? B B+A-C. 3.19 Two vectors appear as in figure 3.19. B Steering wheel which combination of vectors has the largest magnitude . Vectors | Boundless Physics | | Course Hero
