Answer:
Newton's Third Law of Motion
Explanation:
Newton's Third Law of Motion which states that, for every action there is an equal but opposite reaction.
This ultimately implies that, in every interaction, there is a pair of forces acting on the two interacting objects.
In this scenario, a ball bounced by a basketball player on the floor bounces back up at her.
According to Newton's Third Law of Motion, the statement above simply means that in every interaction, there is a pair of forces acting on the two interacting objects i.e the ball and floor. The size of the force on the ball equals the size of the force on the floor. These two forces are called action and reaction forces and are the subject of Newton's third law of motion.
Hence, the ball bounced by the basketball player on the floor would bounce back in equal magnitude.
To solve this problem we will apply the principle of conservation of energy. For this purpose, potential energy is equivalent to kinetic energy, and this clearly depends on the position of the body. In turn, we also note that the height traveled is twice that of the rigid rod, therefore applying these concepts we will have
Therefore the minimum speed at the bottom is required to make the ball go over the top of the circle is 4.67m/s
Answer:
False
Explanation:
The cohesive forces of the liquid are greater than the adhesive forces hence the liquid is drawn inwards instead of spreading out. cohesion refers to the force of attraction between molecules of the same kind. it keeps molecules of the same kind together. It prevents the liquid from spreading out and wetting the glass hence the liquid will have a curved surface when in contact with the glass and this curved surface will be higher than the surface at the center. When the adhesive forces are greater, the curved surface will be lower than the surface at the center.
