This is a number, as of years, days, minutes, or seconds representing such an interval. The
Si standard unit of this is the second
This is the standard Sl (metric) unit of length
This is a change in velocity per time.
This is an object's change in motion per unit time in a specified direction
This is the measured value (always positive) from one point to another.
The vector quantity that defines the distance and direction between two positions.
This is the SI unit of time.
This is a change in the position of a body with respect to time relative to a reference
point.
This is the rate of distance traveled per unit of time, without regard to direction.
This is a line graph that represents acceleration. The slope of the line
w tells us the rate of change in velocity
This is a line graph used to describe the motion of an object. A graphic representation of
velocity. Also used to represent speed.
This is the rate of acceleration of any object falling under the sole
influence of gravity. 9.8m/s

According to social exchange theory, altruistic behaviors benefit the individual who performs them. t/f

What is the relationship between atmospheric pressure and the density of gas particles in an area of increasing pressure? (2 points) as air pressure in an area increases, the density of the gas particles in that area decreases. as air pressure in an area increases, the density of the gas particles in that area increases. as air pressure in an area increases, the density of the gas particles in that area remains constant. as air pressure in an area increases, the density of the gas particles in that area increases and decreases in an alternating pattern. 3. which of the following correctly describes a way in which earth's atmosphere interacts with the geosphere? (2 points) it contains gases that living organisms breathe. it contains gases that trap incoming solar radiation. it provides a medium for cycles that provide nutrients to living organisms. it provides a medium for water to move between earth's surface and the air. 4. which of the following is considered a drawback to using wind energy as a source of power? (2 points) wind energy is nonrenewable. wind energy produces large amounts of air pollution. wind turbines can kill birds that fly through the rotors. wind turbines are built too close to major population centers. 5. a meteorologist predicts that the weather in a region will soon change from clear skies to probable thunderstorms. prior to making this prediction, what did the meteorologist most likely observe on a barometer? (2 points) the barometer fell slightly. the barometer fell substantially. the barometer rose slightly. the barometer rose substantially. 6. which of the following do meteorologists not typically use weather balloons to record? (2 points) atmospheric pressure cloud types humidity temperature 7. during which step in the can crush lab did water vapor force air from the can? (2 points) the can was filled nearly to the top with water. the can was placed on the hot stove top burner for several minutes. the can was removed from the hot stove top burner. the can was placed upside-down in the water-filled pan.
