Megan left her wagon outside while it was raining and it filled with water. When Megan tried to move the wagon that afternoon, she failed to budge the wagon. Why did Megan's wagon become hard to move?A The rainwater increased the force of gravity pushing on the wagon, increasing the force it needed to move.B The rainwater decreased the force of friction pulling on the wagon, decreasing the force it needed to move.C The rainwater decreased the mass of the wagon, decreasing the amount of force it needed to move.D The rainwater increased the mass of the wagon, increasing the amount of force it needed to move.

A student demonstrates one of Newton's Laws of Motion. A trolley, containing a bowl of water is pushed and travels at constant speed. Another student puts his hand in front of the trolley. Some of the water spills forward. WhIch Of Newton's Laws of Motion was the student demonstrating?Group of answer choicesNewton's Law of Universal GravitationMotionNewton's Second Law of MotionNewton's Third Law of MotionNewton's First Law of Motion

A girl brings her wagon up a hill. She needs to hold the handle tightly because Earth's gravity applies a force to the wagon. This force pulls the wagon downward.What is the direction of this force?toward the center of Earthtoward the wagonSubmit
