Do fuses and circuit breakers protect people? When correctly selected and applied, circuit breakers, fuses, and other protection components can help keep workers safe from injuries and machines from damage. Which of the following circuit breakers will reset automatically? Type I: Automatic Reset Circuit Breakers Automatic means a breaker self-resets without help from the user. […]
Which element is more reactive to oxygen?
Which element is more reactive to oxygen? Magnesium has a very high reactivity with oxygen. Magnesium oxide is formed. Zinc burns fairly bright. Is oxygen reactive at room temperature? Oxygen is a highly reactive gas at room… | by ?????????????, scientist & writer | Medium. Is nitrogen reactive or not? Nitrogen is a rather unreactive […]
Can a body have zero velocity and still be accelerating?
Can a body have zero velocity and still be accelerating? Yes, an object can have zero velocity and still be accelerating simultaneously. Then the object will start to move in the backward direction. Is acceleration zero at the turn around point? 4. Acceleration is always smaller then velocity. A point where an object reverses its […]
What causes capillarity and surface tension?
What causes capillarity and surface tension? Adhesion of water to the walls of a vessel will cause an upward force on the liquid at the edges and result in a meniscus which turns upward. The surface tension acts to hold the surface intact. Capillary action occurs when the adhesion to the walls is stronger than […]
What is natural frequency and resonance?
What is natural frequency and resonance? The natural frequency is the frequency at which an object will remain vibrating after hitting it. What happens when you excite that object at the same frequency as its natural frequency? Well, that is resonance. What is the difference between frequency and fundamental frequency? The fundamental frequency is just […]
How is energy transferred and transformed in a bicycle?
How is energy transferred and transformed in a bicycle? Energy transformation While riding a bicycle, the muscular energy of the rider gets transferred into the heat energy and kinetic energy of the bicycle. Heat energy heats the rider’s body. During the transformation, the total energy remains conserved. How many watts is 25 mph? Cycling Power […]
Who gives the equation of motion?
Who gives the equation of motion? Galileo and the Equations of Motion. The first of the three laws of motion formulated by Newton (1642-1726) says that every object in a state of uniform motion remains in that state unless an external force is applied. This is essentially a reformulation of Galileo’s inertia concept. What are […]
What happens during refraction?
What happens during refraction? Refraction is an effect that occurs when a light wave, incident at an angle away from the normal, passes a boundary from one medium into another in which there is a change in velocity of the light. The wavelength decreases as the light enters the medium and the light wave changes […]
Does buoyant force depend on mass?
Does buoyant force depend on mass? The buoyant force depends on the mass of the object. The buoyant force depends on the weight of the object. The buoyant force is independent of the density of the liquid. The buoyant force depends on the volume of the liquid displaced. Does lime remove fluoride? In the present […]
Which of the following is the simplest forecasting method?
Which of the following is the simplest forecasting method? #1 Straight-line Method The straight-line method is one of the simplest and easy-to-follow forecasting methods. What is forecasting and its examples? Forecasting involves the generation of a number, set of numbers, or scenario that corresponds to a future occurrence. For example, the evening news gives the […]
