The resistance of the lamp plugged in to a standard wall outlet with a current of 0.5 amps is 240 Ω (ohms)

Explanation:

In the United States Of America the standard voltage is 120 v and their frequency is 60 Hz

Standard wall outlet voltage is 120 V

The current in the lamp is 0.5 ampere

Resistance (R) = V/ I

      = 120/0.5

      = 240Ω (ohms)

Thus the resistance of the lamp plugged in to a standard wall outlet with a current of 0.5 amps is 240 Ω (ohms).

Which of the following best describes the prime meridian?
ehidna [41]
<h3><u>Answer;</u></h3>

A. The meridian at which longitude is defined to be 0 degrees

<h3><u>Explanation;</u></h3>
  • <em><u>Longitudes are imaginary lines going from south pole to north pole. These lines are known as meridians. Zero degrees longitude is an imaginary line known as the Prime Meridian or the Greenwich meridi</u></em>an.
  • The Prime meridian acts as the starting point for measuring distance both east and west around the Earth. The meridian runs through Greenwich, England and is internationally accepted as the line of 0 degrees longitude.
  • The lines of all longitudes or meridians are great circles, unlike in the case of lines of latitude where only the equator is a great circle.

How much heat is required to convert 0.3 kilogram of ice at 0°C to water at the same temperature
Grace [21]

Answer:

100,200J of heat is required to convert 0.3kg of ice of 0°C to water at same temperature.

Explanation:

Heat = mass * lf

Latent heat of fusion (lf) of water is 334J/g

Heat = 300g * 334 J/g

Heat = 100,200J of heat
