What happens to the charge on each plate if the capacitor remains connected to a battery while a dielectric is inserted? Because the charge is stranded in the capacitor plates, the charge cannot change. Adding the dielectric increases the capacitance by a factor of κ. Increasing C while keeping the charge the same means that […]

How many combinations are there on a 5 button Simplex lock? 1,082 possible combinations How do you change the code on a simplex 900 lock? Simplex Unican 900 Series Code Change Guide Note: If your lock is opening on every turn of the knob or lever, except upon entering a code, this may be a […]

What is the fundamental principle involved in electromechanical energy conversion? For example, an electric motor converts electric energy into mechanical energy. If the conductor is free to move in the direction of the magnetic force, the magnetic field aids in the conversion of electric energy into mechanical energy. This is essentially the principle of operation […]

What is a framing plan? Framing plans for floor and roof construction can be derived directly from the floor plan and must incorporate all information that deals with the configuration of the building. Further, the framing plan shows the layout of the supporting features such as bearing walls, columns, beams, and girders. What is a […]

What kind of force keeps you in your seat when you go around a loop on a roller coaster? inertia How do you find the speed of a roller coaster at the top of a loop? For a roller coaster loop, if it were perfectly circular, we would have a minimum speed of vmin=√gR at […]

What is footing in construction? Footing is a part of foundation which is constructed with concrete or brickwork masonry and acts as a base to the floor columns and floor walls. The main function of footing is to transfer the vertical loads directly to the soil. The term footing is used in conjunction with Shallow […]

How do you calculate die volume? The formula to find the volume multiplies the length by the width by the height. The good news for a cube is that the measure of each of these dimensions is exactly the same. Therefore, you can multiply the length of any side three times. This results in the […]

What is the diameter of a cylinder? The diameter, or the distance across a cylinder that passes through the center of the cylinder is 2R (twice the radius). The surface area of an open ended cylinder (as shown) is 2 RL. What is called the internal diameter of the cylinder? The diameter of the piston, […]
