Question 1 Item 1 The figure presents a diagram of a piece of ticker tape with dots. There are 15 dots on the tape, arranged in a horizontal line. The spacing between the dots is as follows. The first four dots and last four dots are spaced closest together. The dots in the center are spaced further apart. There is a rightward pointing arrow that points to the right in the positive x-direction drawn above the ticker tape. A student performs an experiment in which the horizontal position of a toy car is recorded on ticker tape from a device that places dots on the tape in equal time intervals. The series of dots in the figure represents the motion of an object moving from the negative direction to the positive direction along the horizontal direction. The time interval between each recorded dot is 1s. Which of the following experiments could the student have conducted to create the data shown on the ticker tape? A toy car that initially increases its speed, travels at a constant speed, and then increases its speed again. A toy car that initially increases its speed, travels at a constant speed, and then increases its speed again. A toy car that initially increases its speed, travels at a constant speed and then decreases its speed. A toy car that initially increases its speed, travels at a constant speed and then decreases its speed. B A toy car that initially decreases its speed, stops and then increases its speed. A toy car that initially decreases its speed, stops and then increases its speed. C A toy car that initially decreases its speed, travels at a constant speed, and then increases its speed.

Emmy kicks a soccer ball up at an angle of 45° over a level field. she watches the ball's trajectory and notices that it lands, two seconds after being kicked, about 20 m away to the north. assume that air resistance is negligible, and plot the horizontal and vertical components of the ball's velocity as a function of time. consider only the time that the ball is in the air, after being kicked but before landing. take "north" and "up" as the positive ‑ and ‑directions, respectively, and use ≈10 m/s2 for the downward acceleration due to gravity.

8.29 two streams containing pyridine and acetic acid at 25°c are mixed and fed into a heat exchanger. due to the heat-of-mixing effect, it is desired to reduce the temperature after mixing to 25°c using a stream of chilled ethylene glycol as indicated in the diagram. calculate the mass flow rate of ethylene glycol needed. the heat capacity of ethylene glycol at these conditions is approximately 2.8 kj/(kg k), and the enthalpy change of mixing (δmixh) is given below.
