Why are leaves pink? If the plants break down the chlorophyll and move it out of their leaves before the leaves fall, plants save energy. The plants can reabsorb the molecules that make up chlorophyll. Anthocyanins are other plant pigments that are only made in the fall. These pigments cause red, pink, or purple colors. […]

What is ab initio method in physics?
What is ab initio method in physics? In nuclear physics, ab initio methods seek to describe the atomic nucleus from the bottom up by solving the non-relativistic Schrödinger equation for all constituent nucleons and the forces between them. A significant challenge in the ab initio treatment stems from the complexities of the inter-nucleon interaction. What […]
At what altitude do you become weightless?
At what altitude do you become weightless? Any object that is falling freely is weightless, no matter where it happens to be. This can be the International Space Station at a height of 200 miles, a NASA reduced-gravity airplane at a height of several thousand feet, a drop tower at several hundred feet, or you […]
How does speed affect projectile motion?
How does speed affect projectile motion? Because air resistance affects the horizontal component of a projectiles trajectory, the effect of it can be minimized by lowering the angle of release. Speed or velocity is directly related to distance. The greater the speed of release, the greater the distance covered in flight. Initial Horizontal Velocity. How […]
Is a car driving fast potential energy?
Is a car driving fast potential energy? The kinetic energy of an object is the energy or force that the object has due to its motion. Your moving vehicle has kinetic energy; as you increase your vehicle’s speed, your vehicle’s kinetic energy increases. Is driving a car potential energy? The moving car has kinetic energy, […]
What will happen when the balloon is moved closer to the wall?
What will happen when the balloon is moved closer to the wall? Stage 2 : Move the balloon close to a wall. The negative charges on the wall are repelled away from the balloon and the positive charges are attracted to the balloon. This gives a force of attraction between the balloon and wall. How […]
