D the object must have different temperatures
Answer: The gravitational
Explanation: The student is pushing the box so u have to have gravitational force so it could move
The correct answer is
B. it would move in a line tangent to the circular path
In fact, the centripetal force is the only force that keeps the object in a circular trajectory, pulling the object towards the centre of the circle. When this force is removed, there are no other forces acting on the object, therefore for the law of inertia, the object will continue to move at constant velocity, therefore in the same direction (tangent to the circular path) at constant speed.
Answer:
Newton's First Law states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force.
Explanation:
Objects with less density than water will float when you put them in water.
Objects with greater density than water will sink when you put them in water.
