Answer:

I = 0.15 A

Explanation:

The question is "a lamp subjected to a continuous voltage of 12V , consumes a power of 1.8 W. The intensity of the current passing through the lamp is what"

Given that,

Power of the lamp, P = 1.8 W

Voltage, V = 12 V

We need to find the current through the lamp. The power of the lamp is given by :

P=V\times I\\\\I=\dfrac{P}{V}\\\\I=\dfrac{1.8}{12}\\\\I=0.15\ A

So, the current through the lamp is 0.15 A.

love history [14]

Answer:

625 W

Explanation:

Applying

P = W/t.................... Equation 1

Where p = power, W = Work, t = time

But,

W = Force (F) × distance (d)

W = Fd........................ Equation 2

Substitute equation 2 into equation 1

P = Fd/t.................... Equation 3

From the question,

Given: F = 5000 N, d = 30 m, t = 4 munites = (4×60) seconds = 240 seconds

Substitute these values into equation 3

P = (5000×30)/240

P = 625 Watt

How did Aristotle's inability to detect parallax lead him to propose a geocentric model of the Solar System.
sasho [114]
He reasoned that since parallax could not be observed for celestial objects near the sun, then the earth was stationary. This erroneous assumption was because at the time he had no way of knowing that celestial objects were so far away that their parallax angles were too small to detect.
