Avocados are high in fat. But it's monounsaturated fat, which is a good fat that helps lower bad cholesterol, as long as you eat them in moderation. Avocados have a lot of calories. The recommended serving size is smaller than youâd expect: 1/5 of a medium avocado (or 1 ounce) is 50 calories.
Why do transformers hum? Transformer noise is caused by a phenomenon which causes a piece of magnetic sheet steel to extend itself when magnetized. When the magnetization is taken away, it goes back to its original condition. This phenomenon is scientifically referred to as magnetostriction.
How do I find out the cause of a low frequency hum in my house? It occurs for hours at a time at different times of the day. Sometimes it is steady, sometimes it is pulsing. Sounds like the sound of someone using a compressor nearby-- but it isn't- neighborhood is quiet. Can hear it a bit outdoors in the back of my house. .Called the power co. ,it is not the transformer.
