1. A car speeds up from 10.0 m/s to 45.0 m/s in 4.0 s. What is its acceleration? In your response, show your work, the given and unknown quantities, the equation, and any necessary algebra. Express your answer with the correct number of significant digits.
Can someone help me on 2 science question, this is what they say 1. A teacher challenges.students to study moon phases to determine if what they have learned from the textbook is accurate. How might a student investigate claims made in a textbook that moo. phases occur in a 28-day cycle? A. observe the phase of the moon each night until a full moon can be seen. B. Compare the textbook phases to the actual moon phases seen in the night sky each night in 28 days periods over a three month time frame. C. Compare diagrams of moon phases from the textbook to diagrams of moon phases on-line D. Observe the moon phases seen in the night sky as often as possible over a six month period. 2. What causes the apperance of the moon change overtime? A. The orbit of the Earth around the Moon and its distance from the sun. B.The Moons position relative to the sun and earth as it revolves around sun. C. the rotation of the moon on its axis D. The distance of the moon to the sun thank you

A block hangs at rest from the ceiling by a piece of rope. Consider the forces acting on the block. Is gravity present or absent?
What is the purpose of increasing the length and thinness of a wedge? A)to decrease the distance over which which a force needs to be applied B)to make the wedge lighter and easier to carry C)to increase the mechanical advantage D)to help the wedge to stay clean and well-lubricated Please HELP
Amy gets up from her seat on the train to move closer to the front of the train. Just as she begins to walk toward the front, the train stops at a station. Which of Newton's laws explains what happened to Amy? A. While Amy was walking, her body was in motion, but as the train stopped, it exerted a force on Amy opposite to the direction she was walking and caused her to also stop. This is an application of Newton's Third Law of Motion. B. While Amy was walking, her body was in motion, but when the train stopped, she experienced an unbalanced force and continued to move forward due to inertia. This is an application of Newton's First Law of Motion. C. While Amy was walking, her body was in motion, but when the train stopped, an unbalanced force accelerated her body backward. This is an application of Newton's Second Law of Motion D. While Amy was walking, she was in motion due to the force of repulsion. When the train stopped, she was catapulted forward due to the train's stronger force of attraction. This is an application of Newton's Law of Universal Gravitation.
