What is an example of fungicide? Examples of broad-spectrum fungicides include captan, sulfur, and mancozeb. Some fungicides have a very narrow spectrum of activity; for example, mefenoxam (group 4) is effective only against oomycetes like Phytophthora. Alternatively, a fungicide may affect a broad range of fungi but by only a specific mode of action. What […]

Why is US drinking age so high? In the 1980s a study was done that came back with results that teens were more likely to die in alcohol related automobile crashes than other American adults.

What happen if you coil up a lot of wire? The more loops the coil has, the stronger the magnetic field, while the current is flowing. But when you coil the wire around an iron nail, the magnetic domains inside the nail line up and make a strong, temporary magnet. If you disconnect the wire, […]

What is the effective resistance between A and C? The effective resistance between points A and C is 2/3R. Explanation: Effective resistance of ADC is is 2R as they are in series. What is the difference between effective resistance and equivalent resistance? Effective resistance is defined as theresistance to an alternating current, expressed as the […]

Where do muscles get their energy? The energy is derived from adenosine triphosphate (ATP) present in muscles. Muscles tend to contain only limited quantities of ATP. When depleted, ATP needs to be resynthesized from other sources, namely creatine phosphate (CP) and muscle glycogen. Does body use muscle for energy? Dietician Emily Innes says, “At the […]
