Earthquakes _____. created the rock arches in Utah can be caused by volcanic eruptions are caused by tsunami waves wear mountains down into hills
Weegy: Please read this. [ I am an unfortunate person to save the people eventhough I issued the warning 2 hours before Tsunami struck our coast. Methods for prediction of earthquakes & Tsunami Even though it is difficult to predict, [ the following methods may help. . 1. Seismic gape: - The earthquake at a particular place may occur for every fixed gape of time. By knowing the past records of the quakes affected at that place may help to decide when the earthquake is next due. 2. Planet position.: - When the stress is accumulated at the tectonic plate boundary and the same time if the position of more than 2 planets comes in a straight line this may help to accelerate the earthquakes. There fore the full moon days and new moon days are more vulnerable days for earthquakes. Some time this method fails why? Think of a sick patient. New moon and full moon days are dangerous for only sick patents. These days will not affect the healthy people. The same way if there is no accumulated stress at the tectonic plate boundaries no need to worry about the planet positions. 3. Sun rays falling method: - If you observe the position of the sun rays falling on our wall at a particular time on all days it should form an angular infinity symbol. If there is any deviation in its path it means that there is some difference in height of the earth. That means some strain noticed at that place. Somebody claims that they can predict the place of epicenter by observing this. The laser beam measuring method of earth height from satellite also will help. 4. MDCB:- Chinese scientist claims that they can predict up to 60 % accuracy by sensing electro magnetic rays. 5. Cloud forming: - Few hours to a few days before the occurrence of earthquakes a cloud reader claims that he has noticed a peculiar mosaic type of formation .We may also notice some lightening in the sky. 6. By sound :- A professor from Ajmeer University claims that he was able to hear a low frequency noise under 125 meter ... (More)

A 500-watt vacuum cleaner is plugged into a 120-volt outlet and used for 30 minutes. How much current runs through the vacuum? 900,000 amps 60,000 amps 4.2 amps 0.24 amps

A 500-watt vacuum cleaner is plugged into a 120-volt outlet and used for 30 minutes . How much current runs through the vacuum ?
* there is a rule : P(w) = VI
Where : P(w) is the electric power ( = 500 watt or 500 J/s )
V is the potential difference ( = 120 volt )
I is the current intensity ( = unknown )
So : 500 = 120 * I
I = 500 / 120
I = 4.16 Ampere ( approximately 4.2 Ampere ) ; therefore the answer is 4.2 amps
