What are 2 things required for work to be performed? In order for work to be done on an object, what must happen to the object? A force must be applied to the object and the object must move at least partly in the direction in which the force is applied. What is the formula […]
Do microwaves have radiation?
Do microwaves have radiation? Microwaves are a form of “electromagnetic” radiation; that is, they are waves of electrical and magnetic energy moving together through space. Electromagnetic radiation spans a broad spectrum from very long radio waves to very short gamma rays. But the most common consumer use of microwave energy is in microwave ovens. What […]

What is the direction of acceleration of a particle in a uniform circular motion?
What is the direction of acceleration of a particle in a uniform circular motion? An object undergoing uniform circular motion is moving with a constant speed. Nonetheless, it is accelerating due to its change in direction. The direction of the acceleration is inwards. The animation at the right depicts this by means of a vector […]

How do you explain anomalous results?
How do you explain anomalous results? Anomalous results are odd results – those which are not in keeping with the rest of the results or which do not follow any correlation you have spotted. If you have repeated your experiment several times, you will usually find fewer anomalous results than if you carry it out […]
What happens when a neutron hits a control rod?
What happens when a neutron hits a control rod? If the neutron hits another nucleus, the reaction continues. If the nucleus hits a control rod it is absorbed and no further reaction takes place. 9) Compare the chain reaction that occurs when the control rods are inserted further into the reactor versus when they are […]
What makes a car run rough at idle?
What makes a car run rough at idle? A rough idling engine can be caused by spark plugs or spark plug wires.
