Which of the colors has the longest wavelength? blue 492-455 nm orange 620-597 nm violet 455-390 nm red 780-620
What is red?
200
Different colors of light have different frequencies and wavelengths. What is the relationship between frequency and wavelength
What is:longest wavelength - less frequency, while shortest wavelength - highest frequency
200
How would one best explain the difference between a star's brightness, or apparent magnitude and its absolute brightness?
What is: A star's brightness measures its inherent brightness, and a star's absolute brightness measures its brightness in comparison with that of the Sun.
300
How to best describes the transformation of energy that occurs in a car's engine?
What is: The chemical energy in fossil fuels is transformed into mechanical energy.
300
On the moon, astronauts have decreased weight as compared to on earth even though their mass remains the same.
What is: Law of Universal Gravitation.
300
Within the Sun, heat is transferred through the process of convection. In certain areas, magnetic activity prevents convection from occurring. Which of the following is most likely to occur in one of these areas?
What is: a sunspot
300
Which of the following would most often be measured in light years?
What is: distance between stars and galaxies
300
Which of the following best explains why stars in the night sky are observed as having different shapes and appearances?
What is: distinct, different steps in their life cycles.
400
Which type of thermal energy transfer is occurring as the steam rises into the surrounding air?
What is: convection
400
Law of Universal Gravitation measures weight of an object yet depends on
What is: the mass of two objects and the distance between them
400
When the ball was raised and released on the left side, it hit the stationary balls, and its kinetic energy was transferred all the way to the last ball on the right, causing it to be propelled up. As time went on, the balls did not go as high, and eventually stopped
What is: due to air resistance and friction, some of the energy was transferred to the surroundings.
400

Maryann brews the hot tea and then adds ice to the pitcher. Which direction is the thermal energy flowing in this system?
What is: from the tea to the ice
500
The gravity on Mars is 38 percent as strong as the gravity on Earth. What will happen to the weight and mass of the space vehicle on Mars compared to the weight and mass of the space vehicle on Earth?
What is: The mass will remain the same, and the weight will decrease.
500
What causes light to slow down?
What is: moving into a denser medium
500
The Sun is composed of plasma, a state of matter similar to gas. How does the composition of the Sun most likely affect the Sun's rotation?
What is: The Sun's rotation varies with latitude.
