- Newton's 1st and 2nd Laws of Motion:Question 8 What is inertia? Select one: The tendency of objects to resist change in their motion. The tendency of objects to slow down when not pushed. The tendency of objects to roll toward lower places when left alone. The tendency of objects to speed up under force
- How does the potential energy of the pogo stick before the spring is compressed compare to the potential energy of the pogo stick after the spring is compressed? A The potential energy before compression is more than the potential energy after compression. B The potential energy before compression is less than the potential energy after compression. C The potential energy before compression is the same as the potential energy after compression. The potential energy before compression is twice that of the potential energy after compression.
- Newton's 1st and 2nd Laws of MotioniQuestion 8 Study the image. square The image shows two forces acting on a box. If the box was initially not moving, what will be its motion under the shown forces? Select one: It will not move. It will move toward the left. It will move toward the right. It may or may not move depending on its mass.
- Emerson places a beaker of water on a hotplate and turns the hotplate on. The temperature in the room is 25^circ C After the water heats to 75^circ C she adds pieces of ice to the beaker. Which of the following describes a transfer of heat energy that occurs during this experiment? From the water to the hotplate From the air to the water x From the square disappointed From the water to the ice
- 9. As part of a lab experiment, Tasha drops a metal cube into a beaker of 2 points water as shown in the figure below. After the energy in the form of heat transfers between the substances, what is the final temperature of the water? A. The final temperature is 25^circ C because there is more water than metal. B. The final temperature is 50^circ C because the metal warms the water to the temperature of the metal. C. The final temperature is between 25^circ C and 50^circ C because energy is transferred from the metal to the water. D. The final temperature is between 25^circ C and 50^circ C because most of the thermal energy is lost to the air around the substances.
