Answer: P = I2R = 0.032 x 1000 =0.9 W
Explanation: The power will be the product of the square of the current and
the resistance of the load. The fact that the circuit is a parallel circuit is irrelevant to this question.
Answer:
Explanation:
First we compute the characteristic length and the Biot number to see if the lumped parameter
analysis is applicable.
Since the Biot number is less than 0.1, we can use the lumped parameter analysis. In such an
analysis, the time to reach a certain temperature is given by the following
From the data in the problem we can compute the parameter, b, and then compute the time for
the ratio (T – T)/(Ti
– T)
Answer:
The main gases responsible for the greenhouse effect include carbon dioxide, methane, nitrous oxide, and water vapor which all occur naturally, and fluorinated gases which are synthetic.
Answer:
Architectural engineers apply science and technology to the real world by designing buildings that enhance our standard of living and improve our quality of life. They do this by combining building systems – structural, electrical, mechanical, lighting, acoustics and fire protection - into an integrated whole.
