Question: Answer the following question given this paragraph: Spring tides occur during the new moon and full moon. The Sun and Moon are in a straight line either on the same side of Earth or on opposite sides. Their gravitational pull combines to cause very high and very low tides. Spring tides have the greatest tidal range. Q: What tides occur during the new moon and full moon? A:
OPTIONS:
- autumn
- high
- bottom
- spring
Answer: spring

Question: Answer the following question given this paragraph: Discussion As might have been expected, the player slides a shorter distance by sliding uphill. Note that the problem could also have been solved in terms of the forces directly and the work energy theorem, instead of using the potential energy. This method would have required combining the normal force and force of gravity vectors, which no longer cancel each other because they point in different directions, and friction, to find the net force. You could then use the net force and the net work to find the distance d that reduces the kinetic energy to zero. By applying conservation of energy and using the potential energy instead, we need only consider the gravitational potential energy. Q: What force increases a slide downhill and decreases a slide uphill? A:
OPTIONS:
- nuclear
- frictional
- tension
- gravity
Answer: gravity

Question: Answer the following question given this paragraph: A: Some animals can see light in the infrared or ultraviolet range of wavelengths. For example, mosquitoes can see infrared light, which is emitted by warm objects. By seeing infrared light, mosquitoes can tell where the warmest, blood-rich areas of the body are located. Q: What type of light can mosquitoes see? A:
OPTIONS:
- trichina
- neon
- spicule
- infared
Answer:
infared
