What is the equation to find the final velocity? Final velocity (v) of an object equals initial velocity (u) of that object plus acceleration (a) of the object times the elapsed time (t) from u to v. Use standard gravity, a = 9.80665 m/s2, for equations involving the Earth’s gravitational force as the acceleration rate […]

What is the difference between primary coil and secondary coil? Winding – Transformers have two windings, being the primary winding and the secondary winding. The primary winding is the coil that draws power from the source. The secondary winding is the coil that delivers the energy at the transformed or changed voltage to the load. […]

What causes sudden 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 era called today? Cenozoic How long is a era? An era in geology is a time of several hundred million years. It describes a long series of rock strata which geologists decide should be given a name. An example is the Mesozoic era, when dinosaurs lived on the Earth. An era is […]
