He graph below shows the velocity f(t) of a runner during a certain time interval:
graph of line going through ordered pairs 0, 4 and 4, 8. graph of another line going through ordered pairs 4, 8 and 8, 0. label on the x axis is time in second and label on the y axis is velocity in meter per second
which of the following describes the intercepts on the graph?
the initial velocity of the runner was 4 m/s, and the runner stopped after 8 seconds.
the initial velocity of the runner was 8 m/s, and the runner stopped after 4 seconds.
the initial acceleration of the runner was 4 m/s2,

1. study the scenario. the particles in some system are moving around quickly. a few minutes later, the particles are moving, on average, more slowly. how does this change in motion affect the temperature of the system? the temperature of the system did not change. the speed of the particles does not affect temperature, the number of particles affects the temperature.the temperature of the system is lower now than it was initially. faster moving particles result in a higher temperature for the system.the temperature of the system is higher now than it was initially. slower moving particles result in a higher temperature for the system.the temperature of the system did not change. the speed of the particles has no effect on the temperature, only the type of atom affects the temperature.
