Since the planets roughly orbit the Sun in the same plane as the Earth, where should the planets be seen in the sky relative to the ecliptic?
You do not need to pause to record your data as you perform your experiment. You can go back and estimate the values when the experiment is complete. True or False True False
You can find many different stars and constellations using the Big Dipper as a guide! For instance, by using the handle of the Big Dipper, you can find __ Arcturus in Bootes Regulus in Leo Castor and Pollux in Gemini Polaris in Ursa Minor
Match the definition to the correct term. a substance that is released I into the atmosphere the energy that holds protons and neutrons together in an atomic nucleus renewable energy from plants and animals a. nuclear energy b. emission c. biomass
What explains the reason for having to cook food for longer at high altitudes? The atoms that make up the food behave differently at lower atmospheric pressure. The lower atmospheric pressure causes the boiling temperature to be lower. The food molecules stick together more and require more energy to separate them.
As the temperature of the gas in a balloon decreases, which of the following occurs? The volume of the balloon increases. The average kinetic energy of the gas decreases. The gas pressure inside the balloon increases. all of the above
How is radiation different from convection and conduction? It can travel through empty space. It can travel through matter. It can travel through water.
Match this description with the term that closely matches it: Process that lowers the average speed of molecules in a liquid.
What does one prolonged blast emitted by Boat A using an efficient sound producing device indicate?
Question: When rounding a curve a car tends to: Options: Speed up. Move to the inside of the curve. Stay in the center of the lane. Move to the outside of the curve.

Learning Log: How do you think you get something to have more kinetic energy?
If a UV light unit has four lamps in it, and each lamp is 7-watt, it is known as a __ 7-watt unit 28-watt unit 11-watt unit 3-watt unit
10. What is the mass of a meteorite that is traveling towards Earth at $1,760m/s$ with a momentum of $33,400kgm/s$
Where is the energy coming from in the lab (where does it start)? A Potential energy in the Cheeto B Potential energy in the water C Kinetic energy inside the water D Kinetic energy in the Cheeto
What should happen to the temperature of the water? A It stays the same B It goes down C It goes up
9. Your local weather report announces that the barometric pressure is 30.44 inHg. Convert this pressure to psi, atm torr, and Pa.
Express the temperature, 275.18 K in degrees Celsius. $548.33^{\circ }C$ $274.17^{\circ }C$ $2.03^{\circ }C$ $120.88^{\circ }C$ $22.78^{\circ }C$
Hubble's Law has led physicists and astronomers to the hypothesis that the universe is expanding. True False
Newton determined that the force of gravity on an object is proportional to its mass causing its mass to be canceled out (Newton's second law) and resulting in a constant acceleration. If the laws of physics are universal, then Newton should be able to apply his discoveries about gravity on Earth to the motion of the planets in our Solar System. Newton's third law says that for every force there is an equal reaction force in the opposite direction. What does this imply about the force of gravity associated with a person standing on the Earth? Choose one: A. The force of gravity on the person cancels out to zero. B. The Earth's gravity pulls downward on the person but also pushes upward on them. C. The Earth's gravity pulls downward on the person, and the person's gravity pulls upward on the Earth. D. There is twice as much gravitational force on the person than there would be if it weren't for Newton's third law.
