An 1,840 W toaster, a 1,460 W electric frying pan, and a 50 W lamp are plugged into the same outlet in a 15 A, 120 V circuit. (T

shutvik [7]

Answer:

Explanation:

Given

Power drawn by toaster $P_1=1840\ W$

Power drawn by Electric fan $P_2=1460\ W$

Power drawn by lamp $P_3=50\ W$

Voltage applied $V=120\ V$

If appliances are applied in parallel then Voltage applied is same

Power is given by $P=\frac{V^2}{R}$

Resistance of toaster $R_1=\frac{120^2}{1840}=7.82\ \Omega$

Resistance of electric Fan $R_2=\frac{120^2}{1460}=9.86\ \Omega$

Resistance of toaster $R_3=\frac{120^2}{50}=288\ \Omega$

Current is given by

$I=\frac{V}{R}$

$I_1=\frac{120}{7.82}=15.34\ A$

$I_2=\frac{120}{9.86}=12.17\ A$

$I_3=\frac{120}{288}=0.416\ A$

Are there any difference betwn supersonic planes and concorde planes

malfutka [58]

<u>Answer</u>:

Yes, there are differences between supersonic planes and concorde planes

<u>Explanation</u>:

The supersonic planes moves faster than the speed of sound. But these flights are banned because it is economically non-starter. It has more loud sound equivalent to the explosion. The banned was elevated in 2003, due to new aviation law. The concords travel twice the speed of sound. This planes holds the record for the fastest planes but seen to be fleet long back i.e. in 2003. These were banned when a fatal crash had been reported. And now are only found in the museums.

A particle of mass m is placed in a three-dimensional rect- angular box with edge lengths 2L, L, and L. Inside the box the poten

QveST [7]

Answer:

the energy of groud state = $\frac{9h^{2} }{32ml^{2} }$

Explanation:

the energy of a 3 dimensional rectangular box is given by $\frac{h^{2} }{8m} (\frac{n_{x} ^{2} }{l_{x} ^{2} } +\frac{n_{y}^{2} }{l_{y} ^{2} }+ \frac{n_{z}^{2} }{l_{z} ^{2} })$

where h is planks constant m is the mass of the particle $n_{x}$ , $n_{y}$ and $n_{z}$ are principal quantum number in x y and z direction. and $l_{x}$ , $l_{y}$ and $l_{z}$ are length of box in x y and z direction.

therefore the energy of ground state will be when $n_{x}$ , $n_{y}$ and $n_{z}$ = 1

therefore energy of ground state = $\frac{h^{2} }{8m} (\frac{1 ^{2} }{2l ^{2} } +\frac{1^{2} }{l^{2} }+ \frac{1^{2} }{l ^{2} })$

= $\frac{9h^{2} }{32ml^{2} }$

7. Explain why observations of comets and shooting stars presented challenges to ancient astronomers using

Lelu [443]

According to Ptolemy's model, he, too, believed in a geocentric Universe and that the planets and stars were perfect spheres, though Earth itself was not.

He further thought that the movements of the planets and stars must be circular since they were perfect and, if the motions were circular, then they could go on forever.

<h3>What is comets and shooting stars?</h3>

Shooting stars are very different from comets, although the two can be related. A Comet is a ball of ice and dirt, orbiting the Sun (usually millions of miles from Earth). ... A shooting star on the other hand, is a grain of dust or rock (see where this is going) that burns up as it enters the Earth's atmosphere.
