What are the three factors to consider in the flow of electrons?
What are the three factors to consider in the flow of electrons? To produce an electric current, three things are needed: a supply of electric charges (electrons) which are free to flow, some form of push to move the charges through the circuit and a pathway to carry the charges. What’s another word for current […]

How does the number of electrons affect the properties of an atom?
How does the number of electrons affect the properties of an atom? The number of electrons, in turn, determines the chemical properties of the atom. The electrons arrange themselves in energy levels around the nucleus. The outermost or valence electrons of an atom are the ones that take part in chemical reactions. An element’s chemical […]
What causes complete brake failure?
What causes complete brake failure? The most common cause of brake failure is loss of brake fluid. The fluid transfers the force you exert by pushing down on the brake pedal to the brake disks that slow and stop your car’s wheels. A bad brake cylinder can cause your braking system to lose power. A […]

What is the formula for pulleys?
What is the formula for pulleys? Calculate the force caused by gravity on the basic pulley system using the following equation: G = M x n (gravitational acceleration). The gravitational acceleration is a constant equal to 9.8 m/s². The mass M = 9g, so G = 9g x 9.8 m/s² = 88.2gm/s², or 88.2 newtons. […]
