What force causes current to flow? Electric current is flow of electrons in a conductor. The force required to make current flow through a conductor is called voltage and potential is the other term of voltage. For example, the first element has more positive charges, so it has higher potential. What’s the minimum voltage at […]
Why is sediment transport important?
Why is sediment transport important? Sediment transport is applied to solve many environmental, geotechnical, and geological problems. Measuring or quantifying sediment transport or erosion is therefore important for coastal engineering. Movement of sediment is important in providing habitat for fish and other organisms in rivers. What are two ways water transports sediment? How do rivers […]
What are the advantages of a dynamic microphone?
What are the advantages of a dynamic microphone? Key advantages to a dynamic microphone: Rugged and able to handle high sound pressure levels, like those delivered by a kick drum. Provide good sound quality in all areas of microphone performance. They do not require a power source to run. They are relatively cheap. What do […]
What determines the period of a pendulum quizlet?
What determines the period of a pendulum quizlet? What determines the period of a pendulum? The length of the pendlum and the acceleration of gravity. The time it takes for a wave to complete one cycle. A long pendulum has a longer period than a shorter pendulum. Where is the most kinetic energy on a […]
Can 2 remote control cars same frequency?
Can 2 remote control cars same frequency? If you don’t plan to run your RC cars, trucks, boats, or aircraft alongside other radio controlled vehicles, it doesn’t really matter which frequency they use. However, running two 27MHz or two 49MHz RC cars near each other will usually result in interference—crosstalk. The radio signals get mixed […]
What is the difference between 6ka and 10kA MCB?
What is the difference between 6ka and 10kA MCB? The main difference between the two is their capacity, with the MCB rated under 100 amps with an interrupting rating of under 18,000 amps. How do you calculate kA rating? The maximum amount of current that can flow through a circuit is determined by the size […]
What is the angle of reflection when the incident ray makes an angle of 30 0 with i the normal II the mirror?
What are the first signs of heat stress?
What are the first signs of heat stress? WHAT TO LOOK FOR Heavy sweating. Cold, pale, and clammy skin. Fast, weak pulse. Nausea or vomiting. Muscle cramps. Tiredness or weakness. Dizziness. Headache. What is the difference between heat stress and heat stroke? Both heat exhaustion and heat stroke are serious conditions. Heat exhaustion begins with […]
What is the relationship between resistance and current?
What is the relationship between resistance and current? The relationship between current, voltage and resistance is expressed by Ohm’s Law. This states that the current flowing in a circuit is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit, provided the temperature remains constant. What is the property of […]
Is it bad to look at IR light?
Is it bad to look at IR light? All infrared, visible or ultraviolet electromagnetic radiation can cause injury to the eye in sufficient concentrations, but this is very rare. Infrared lamps and incandescent bulbs are not powerful enough to cause such harm. But it’s best if you don’t stare directly at them for too long. […]
