A student removes a pitcher of chilled
lemonade from a 5°C refrigerator and
leaves the pitcher in a 20°C room for
several hours. Which of the following
statements best describes the flow of
energy during this time?
A. Cold energy flows from the
lemonade to the room until the room
is colder than the lemonade.
B. Heat energy flows from the room to
the lemonade until the lemonade is
warmer than the room.
C. Cold energy flows from the
lemonade to the room until the
lemonade and the room are the
same temperature.
D. Heat energy flows from the room
to the lemonade until the lemonade
and the room are the same
temperature.
Graph title is Motion of Four Cars. The X-axis title is Time, seconds and ranges from zero to five in increments of one. The Y axis is Distance, meters and ranges from zero to twenty five in increments of five. The four straight lines on the graph representing the motion of Car A, Car B, Car C, and Car D all begin at zero minutes, zero meters. The curves do not touch or cross each other.
The distance each car has traveled after five seconds is:
Car A -- 25 meters
Car B -- 20 meters
Car C -- 11 meters
Car D -- 5 meters
Which car had an average speed of 4 m/s?
Car A
Car B
Car C
Car D
When the ball in motion collides with the others ...
... it and the others will sway because of the force of impact.
... it will bounce back because the others have more inertia.
... it will stop while a ball of equal mass at the opposite side will move away because of equal-opposite reactions.
... the force, mass and acceleration will equalize.
