![]() ![]() Of the following choices, which is the best description of g? g is the magnitude of the acceleration due to the force of gravity. The ball falls farther in the second 3-second interval than it does in the first interval. Consider how far the ball falls in its first 3 seconds of free fall (from t = 0 s to t = 3 s) compared to how far it falls in its next 3 seconds (from t = 3 s to t = 6 s). the object is speeding up A ball is dropped off of a tall building and falls for 6 seconds before landing on the ground. This position versus time graph exhibits what kind of motion between points Q and R? A moving object that is speeding up If an object's acceleration vector points in the same direction as its instantaneous velocity vector then you can conclude _. How is the car moving? The car is slowing down. In the motion diagram, a car is driving to the right and there are equal time increments between frames. The graph decreases linearly with a constant negative slope. Which of the following velocity versus time graphs best represents the motion of a ball that was thrown upward, from just after it was thrown until just before it is caught on the way down? Velocity versus time graph starting with a positive, non-zero initial velocity. Which of the following vectors best represents the car's displacement from point A to point B? A position vector longer than position A and shorter than position B, pointing to the right. The smaller vector shows the car's initial position and the larger vector shows the car's final position. What is the answer with the correct number of decimal places? 38.9 cm A car moves from position A to position B. 3.45 x 104 You perform the calculation: 32.0 cm + 6.92 cm on your calculator and its output is 38.92. 5280 ft over 1 mi or 1mi over 5280 ft Convert 34,500 to scientific notation with three significant figures. 1.0 yd = 91 cm Using the table of equalities, select the correct conversion factors that indicate the number of feet (ft) in one mile (mi). Remember to select an answer with the correct number of significant figures. 5.795 × 102 Which pair correctly matches the prefix symbol with its multiplier? G, 1.0 × 109 Calculate the number of centimeters (cm) in 1.0 yard (yd). meters How many significant figures are there in the measured quantity 64.00 s? Four significant figures Convert 579.5 to scientific notation. 1 picometer, 1 nanometer, 1 millimeter, 1 decimeter Complete the relationship. 8.310 × 10-4 How many significant figures are there in the measured quantity 0.0304 m? Three significant figures Rank the following in order of increasing size (smallest to largest). What is the answer with the correct number of significant figures? 209 Convert 0.0008310 to scientific notation with four significant figures. 3930 What is the multiplier for the prefix centi-? 0.01 How many significant figures are there in the measured quantity 1.52 x 103 kg? Three significant figures You perform the calculation: 35920 / 172 on your calculator and its output is 208.837209. Convert 3.93 × 103 from scientific notation to standard notation.
