How do you find the velocity of a satellite orbiting the Earth? The orbital speed can be found using v = SQRT(G*M/R). The R value (radius of orbit) is the earth’s radius plus the height above the earth – in this case, 6.59 x 106 m. Substituting and solving yields a speed of 7780 m/s. […]
How do you make a first order low pass filter?
How do you make a first order low pass filter? First Order Low Active Pass Filter Inverted Configuration The inverting low pass filter is designed using IC741, an Op-Amp with 8 pin configuration. In inverting mode, the output of the Op-Amp is 180 degrees out of phase with the input signal. Initially, the Op-Amp has […]
How do you conduct a simple conductivity test?
How do you conduct a simple conductivity test? Wrap a small piece of aluminum foil around one of the exposed wires running from the light bulb, then gently push the foil-wrapped wire end into the positive terminal of the battery. Use the tape to secure and completely cover over the inserted foil-wrapped wire. Roll small […]
What are the materials used for construction?

One of the oldest, most traditional building materials around the world is of course timber. Steel. Plastic. Stone. Textiles. Glass. Brick. What materials are used […]
What is the conductance of a 1000 ohm resistor?
What is the conductance of a 1000 ohm resistor? 0.001 siemens How do you calculate conductance from resistance? Conductance is the opposite of resistance: the measure of how easy it is for electric current to flow through something. Conductance is symbolized with the letter “G” and is measured in units of mhos or Siemens. Mathematically, […]
What are the most common mechanical injuries?
What are the most common mechanical injuries? The most common mechanical equipment injuries are to hands and fingers, which may be cut, sprained, dislocated, broken, crushed or cut off by machinery or tools. Eye injuries can be caused by heat or radiation or by objects thrown from moving mechanical parts. What causes injury when working […]
Why do transition metals have 2 valence electrons?
What is commercial refrigeration system?
What is commercial refrigeration system? Using this principle, commercial refrigeration systems utilize a refrigerant solution to transfer heat from the food inside the refrigeration unit’s storage area to the refrigerant. Refrigerant solutions obey a second physical principle, which states that gases cool as they expand and heat up as they are compressed. What is marine […]
Which type of bearing metal is self lubricated?
Which type of bearing metal is self lubricated? Oil impregnated bronze: Bronze bearings are very porous and have lightweight oil soaked into the material. Under the optimum conditions, this oil is drawn to the bearing surface creating a lubricated layer between the bearing and the shaft. What is the material used in bearing? Most ball […]
What are safety checks for CNG vehicle?
What are safety checks for CNG vehicle? Follow these simple steps to ensure your CNG powered car’s safety: Get your CNG cylinder and equipment checked by a professional at least once every 5 years for regular wear and tear. CNG cylinder pressure should not exceed 200 bars. You can check that on the gauge that […]
