How do you test a start capacitor with a digital multimeter? How to measure capacitance Use your digital multimeter (DMM) to ensure all power to the circuit is OFF. Visually inspect the capacitor. Turn the dial to the Capacitance Measurement mode. For a correct measurement, the capacitor will need to be removed from the circuit. […]

Why are methane hydrates dangerous to ships? An odorless gas found naturally, and caused by decomposition of organic material, methane becomes solid under the pressure of the ocean and can get locked into ice-like crystals called hydrates. Releasing the pressure suddenly can be a danger to oil workers, who call the results “burps of death.” […]

Why would airbags not deploy? Defective Components As with any other car part, it is possible for airbag sensors to fail to correctly detect impact or deploy the airbag, as the result of improper design, testing or installation of sensors, or because of software failure.

Which of these will increase the resistance of a wire? Decreasing the length of the wire will increase the resistance of the wire. 5. Increasing the cross-sectional area of the wire will increase the resistance of the wire. When electricity passes through a thin wire what does it become? Electricity flows through a thin wire […]

How does follow through effect? Instead, the follow-through increases the time of collision and subsequently contributes to an increase in the velocity change of the ball. By following through, a hitter can hit the ball in such a way that it leaves the bat or racket with more velocity (i.e., the ball is moving faster). […]

Why would an egg break immediately when it hits the ground? It is because of the gravity, the mass of the egg, and the force exerted by the ground to the egg. Explanation: Gravity causes an object to fall to Earth when dropped. The impact made by the speed of the egg and its mass […]

What does dilation mean in math? similarity transformation Is scale factor new over old? For figures which differ by a scale factor, the scale factor is the ratio of corresponding side lengths (new image to old image). What does a scale factor of 5 mean? Share on. Statistics Definitions > A scale factor is a […]

Where should an object be placed in order to use a convex lens as a magnifying glass? A convex lens acts as a magnifying glass, when it forms a virtual, erect and magnified image of an object. For this, the object is to be placed between principal focus and optical cantre of the lens. Where […]

Can Superman go into the speed force? Superman has no connection to the speed force. He moves at superluminal speeds because he can. But even with that speed, he is not half as fast as the Flash. Superman by all accounts can move billions of times the speed of light. Can the speed force be […]
