The diagram shows a wooden block being pulled up an inclined plane that is 30 cm in height. Using the inclined plane reduces the amount of force needed to life the block while increasing the-
mass of the wooden block.
surface area of the block.
pull of gravity on the block.
distance the block must move.
What is the disadvantage of using an inclined plane to life a heavy object?
The object must be moved a greater distance.
It takes less effort to move the object.
Many objects are difficult to lift straight up.
Heavy objects usually take up more space.
The illustration shows a wooden block being pulled up an inclined plane with a spring scale. What change in the experimental setup would require less force to pull the block up the inclined plane?
Using a much longer inclined plane.
Pulling the wooden block more quickly.
Reducing the mass of the wooden block.
Increasing the height of the inclined plane.
The diagram shows two ramps that a person could use to raise a 10-kilogram cardboard box to a height of 1 meter. Which statement correctly describes the force required to raise the box using the ramps?
A. The same amount of force will be required when using either ramp because both boxes have a mass of 10 kg.
B. The same amount of force will be required when using either ramp because both ramps are 1 meter high.
C. Less force will be required to raise the box using Ramp Y because Ramp Y is longer than Ramp X.
D. More force will be required to raise the box using Ramp Y because Ramp Y is longer than Ramp X.
Which of the following is a disadvantage of using coal as an energy resource?

The following picture is an example of what energy source?
Wind
Biomass
Coal
Hydropower
A disadvantage of this energy source is that it pollutes the air with gases.
hydropwer
wind

solar
Which energy resource does not produce greenhouse gases ?
coal energy
petroleum energy
wind energy
gas energy
Which energy source is considered nonrenewable?
Wind energy
Nuclear energy
Solar energy
Biomass energy
