What is bouncing effect? Bounce Animation effect is used to move the element quick up, back, or away from a surface after hitting it. What is bouncing button? When a switch is toggled, contacts have to physically move from one position to another. As the components of the switch settle into their new position, they […]

What affects the strength of van der Waals forces? Number of Electrons Held by the Atoms/Molecules The greater the number of (instantaneous) dipoles formed, the greater the strength of the Van der Waals force. What are the three types of van der Waals forces? van der Waals forces may be classified into three types: electrostatic, […]

What happens to bimetallic strip when heated? When this bimetallic strip is heated, the brass expands more than the steel and the strip curves with the brass on the outside. If the strip is cooled, it curves with the steel on the outside. Bimetallic strips are used as switches in thermostats. Why is a bimetallic […]

Does force equal mass times velocity? The first equation states that a Force is equal to Mass times Acceleration, or Newton’s second law of motion. The second one states that Momentum (P) is equal to Mass times Velocity. You can see that the difference lies between velocity and acceleration: acceleration is the rate of change […]

What is the structure of membranes? The plasma membrane is composed of a bilayer of phospholipids, with their hydrophobic, fatty acid tails in contact with each other. The landscape of the membrane is studded with proteins, some of which span the membrane. Some of these proteins serve to transport materials into or out of the […]
