A seaside community decides to build a barrier to reduce erosion and other damage to the beach ecosystem. The barrier needs to be able to withstand harsh winter winds and strong spring storms. Winds in the area usually produce a force between 3 and 10 newtons. Community leaders evaluate their options based on the strength and the cost of each barrier material and how often each material will need to be repaired or replaced. Which material will be the best choice for building the barrier?
Natural Rock
Wood
Steel
Concrete
engineers have designed a hydrogen fuel cell car which is powered by the energy that is released when hydrogen and oxygen combine. To do this, the car's engine transforms chemical energy into mechanical energy. The only substance released from these cars is water vapor.
A student claims that cars powered by this type of fuel have an advantage over cars powered by gasoline. Which statement supports this student's claim?
Hydrogen fuel cell cars do not contribute to air pollution because their only exhaust is water
Hydrogen fuel cell cars do not require maintenance like gasoline powered cars do.
Hydrogen fuel cell cars use non-renewable energy sources
Hydrogen fuel cell cars can be designed in a variety of shapes.
The picture shows a room with a ceiling fan and a fireplace. Heat from the fire warms the room. As fuel in the fireplace is burned, the fire gets smaller and then goes out. Then the air near the floor feels cooler. A person turns on the ceiling fan and the air temperature near the floor begins to increase after the fan is turned on.
Which of these best explains why the air temperature near the floor increases after the person turns on the fan?
Fires produce more thermal energy when the fan blades rotate
The rotating fan causes warm air near the ceiling to move throughout the room by conduction
the rotating fan pushes warm air that rose to the ceiling by convection back down into the room.
Warm air from inside the room is drawn back into the fireplace when fan blades rotate.
A student drew a diagram to illustrate convection currents in the atmosphere.
How should the diagram be changed to accurately illustrate atmospheric convection currents?
add coral and fish to the water to represent energy flow.
add trees and bushes to the land to represent transpiration
add an arrow pointing up from the land to represent warm air rising and an arrow pointing down over the water to represent cool air sinking.
add an arrow pointing down over the land to represent cool air sinking and an arrow pointing up from the water to represent warm air rising.
A student pushed a toy car along a level track toward a spring. The car collided with the spring, causing the spring to compress. After the spring decompressed, the car traveled backward a short distance before stopping.
Which statement accurately explains the energy transformation that occurred during the collision with the spring?
As the car is compressing the spring, elastic potential energy in the spring is converted to kinetic energy in the car.
As the car is compressing the spring, kinetic energy in the car is converted to elastic potential energy in the spring
as the spring is releasing, kinetic energy in the car is converted to elastic potential energy in the spring
as the spring is releasing, kinetic energy in the spring is converted to kinetic energy in the car.
Asian Carp are fish that are not native to Tennessee. These fish are present in many rivers in the state. Adult Asian carp are very large and have few predators in Tennessee. The rivers on the map that are colored black show where the Asian carp have been found in 2016.
Many native fish, such as yellow perch, consume plankton in the rivers where they live. Asian carp also consume this food. Based on the information provided, yellow perch living in the Duck River most likely:
have greater competition for resources than yellow perch living in the Holston river.
develop fewer illnesses than yellow perch living in the Cumberland river.
are better adapted to the environment than yellow perch living in the Tennessee river
have a greater number of predators than yellow perch living in the Mississippi river/
The graph shows the number of native species present in a location over a 6-year period of time.
The most likely reason for the change in native species from 2005 to 2009 is:
a struggle for resources
an increase in food availability
a decrease in predators
a change in the soil composition
a diagram of wind blowing up the side of a mountain is shown.
The windward side of the mountain receives more rain than the leeward side. Which of these correctly explains why?
Air cools, condenses, and gains moisture as it falls down the mountain.
Air warms, condenses and loses moisture as it falls down the mountain.
Air warms, condenses and gains moisture as it rises up the mountain.
air cools, condenses and loses moisture as it rises up the mountain.
The graph shows temperature and barometric pressure data during a week for a city.
Based on the data, what change in the weather pattern can be seen Friday morning?
Storm clouds are increasing because of a pressure rise
the sky is clearing because of a rise in temperature
the sky is beginning to clear because of a pressure rise
rain clouds are moving in because of pressure lowering
the line graph shows the average air temperatures in a coniferous forest and a deciduous forest.
which conclusion about deciduous forests is best supported by the data in the graph?
deciduous trees grow in areas with cold summers
Deciduous trees grow in areas with plenty of rain
On average, winters in deciduous forests are 30 degrees colder than winters in coniferous forests.
On average, deciduous forests are ten degrees warmer than coniferous forests throughout the year.
Study the image and use it to answer the questions below.
A student uses the setup shown to investigate ways to dry out a wet sponge. The student submerged the sponge in water for 5 minutes, then placed it next to a fan for their first trial. In the second trial, the student submerged the sponge in water again for 5 minutes, then placed it in the light of a lamp in an otherwise dark room.
Which of these about the setup shown is true?
Radiation from the lamp will cause the sponge's temperature to increase.
The wet sponge will be heated via conduction by the lamp, and convection by the fan.
The fan will transfer more thermal energy to the wet sponge than the lamp.
Heat from both the fan and the lamp will travel to the wet sponge via conduction.
A wrecking ball is shown.
Which of these changes would cause the most damage to the building in the image?
Doubling the mass of the wrecking ball from 300 to 600 kg.
Tripling the mass of the wrecking ball from 200 to 600 kg and halving its velocity from 12 to 6 m/s.
Decreasing the mass of the wrecking ball from 500 kg to 100 kg and increase its velocity from 1 to 2 m/s.
Doubling the mass of the wrecking ball from 300 to 600 kg and doubling its velocity from 6 to 12 m/s
A student studies the diagram shown. The arrows in the diagram represent a typical flow of wind over a mountain.
the student correctly explains the expected atmospheric conditions in the diagram. Which three statements should be part of the students explanation?

The humid air travels up the mountain and falls back down the other side.
Location A is a dry location.
The humid air cools as it is rising to the top of the mountain and turns to clouds.
