A noncontinuous loop that prevents the flow of current is a(n) <u>open</u> circuit.
The word giga is a prefix in the metric system which
stands for a factor of billion while the hertz is a unit which is also
equivalent to cycle / s (cycle per second).
Therefore the answer to this is:
<span>2 gigahertz = 2 billion cycles per second</span>
Power = (voltage) x (current)
(1,200 W) = (120 V) x (current)
Current = (1,200 watt) / (120 volt) = 10 Amperes.
How long the heater heats is irrelevant. The current
is flowing all the time, whenever the heater is running.
Answer:
Work is done in moving a charge of 2 coulomb across two points having a potential difference of 12 volt is 24 joule .

Answer:
(c) reduce atmospheric blurring
Explanation:
Observatories are the locations used to study the celestial events, climate, astronomy etc. As the observations are made with the radio and visible light of the electromagnetic radiations. So in order to have the clear view, observatories are made at higher places far from population, in the dark areas having clear air, where they can clearly observe the sky. Atmospheric blurring is caused by the atmospheric turbulence. That cause the light coming from the stars to get slightly refracted thus effecting the results of the telescopes. In order to overcome it observatories are made at specific places like on the highest mountaintops.
