- Two applied forces are exerted on a box that slides along a flat surface with negligible friction. The force on the right is at an angle Theta to the horizontal, as shown The box is initially moving to the right at a constant velocity. The angle Theta is then slowly decreased, but the magnitudes of the applied forces remain constant. Which of the following correctly describes the motion of the box as the angle is decreased? A The velocity of the box remains constant because the sum of all the forces on the box remains constant. B The velocity of the box remains constant because the horizontal components of the forces do not change. C The velocity of the box changes because the sum of the vertical components of the forces no longer equals zero D The velocity of the box changes because the sum of the horizontal components of the forces no longer equals zero.
- A block of mass 2.0 kg is initially at rest on a horizontal surface. The block is pulled a distance of 10 m in 3.0 s by an applied force. The coefficients of static and kinetic friction between the surface and the object are mu _(s)=0.45 and mu _(k)=0.30 respectively. The magnitude of the applied force is most nearly A square B square C square square D
- Seasons Due to Earth's orbit around the sun constellations may only be visible during certain __ As the Earth revolves around the sun, the __ is moving but the stars in the sky are not. Earth moves through each section of the sky throughout the year, making only the constellations in that area __
- You've found the body of someone who looks like they have been stabbed to death. Using the scientific method, walk through the steps you might take. You can fill in elements of the scene/event as needed for conducting an experiment based on evidence you can pretend you have found. 2. Imagine you are investigating a crime scene and you notice five sets of shoe prints.Give two examples of scalar quantities that you may notice with this evidence and two examples of vector quantities that you may notice and say what each of these four quantities may tell you about the crime scene.
