What is slew rate formula? Slew rate = 2 π f V. Where. slew rate is measured in volts / second, although actual measurements are often given in v/µs. f = the highest signal frequency, Hz. V = the maximum peak voltage of the signal. What is meant by CMRR? Op Amp Common-Mode Rejection Ratio […]

How do I choose a tire pressure gauge? The most important decision is to get a gauge that works within the pressure range of the tires that you will be using the gauge on. For example, if you run 30 psi in your tires then you should get a 60 psi gauge. If you run […]

How do you calculate angular velocity from RPM? Revolutions per minute can be converted to angular velocity in degrees per second by multiplying the rpm by 6, since one revolution is 360 degrees and there are 60 seconds per minute. If the rpm is 1 rpm, the angular velocity in degrees per second would be […]

How does a pitot tube work? Pitot tubes work as flow sensors to measure the speed and pressure of air, liquid or gas. The front hole measures the stagnation pressure, while the side openings (static ports) gauge static pressure. The difference between these two measurements is called dynamic pressure – this is what is used […]

What is the type of rock formed from lava that cools quickly? When lava comes out of a volcano and solidifies into extrusive igneous rock, also called volcanic, the rock cools very quickly.

How much power does a vertical wind turbine produce? Computers control the pitch of the blades and the direction they point to produce maximum power. Most onshore wind turbines today are rated at 2.5-3 MW (megawatts), with blades of about 50m in length, about half the length of a football field. What are two advantages […]

What should you do when there is a vehicle coming from the opposite direction in your lane? A vehicle is approaching from the opposite direction, going straight ahead.
