What is the approximate power per area emitted by the inside wall of an oven when baking a cake in w/m2?

The approximate power per area emitted by the inside wall of an oven when baking a cake in w/m2 is 6 x 3^4.

<h3 /><h3>What is  power per area?</h3>

Comparing the surface power density of various industrial energy sources is crucial. Geographer Vaclav Smil popularised the idea. In the pertinent literature, the phrase is sometimes abbreviated to "power density," which may cause confusion with similar or homonymous concepts.

The power obtained per square metre of Earth's surface area utilised by a particular energy system, including all supporting infrastructure, manufacturing, fuel mining (if relevant), and decommissioning, is expressed in W/m2. Due to the high power density of fossil fuels and nuclear energy, substantial amounts of electricity may be produced in very small spaces at power plants.

6 x 3^4 (for reference Humans are about 300 K)

Why can't krypton and xenon separate during the separation of gases in the air?
In-s [12.5K]

Answer:

The remaining gas is a mixture of argon, neon, krypton, and xenon. Because these elements are chemically very unreactive, chemical means cannot be used to separate them.

Are bf3 and nf3 symmetrical or unsymmetrical molecules? explain.
Degger [83]

The correct option is this: BF3 IS SYMMETRICAL WHILE NF3 IS UNSYMMETRICAL.

Symmetry is used in chemistry to explain the structure of chemical substances, that is, it is used to explain how the particles in chemical substances are arranged. In chemistry, molecular symmetry is used to explain the behavior of chemical substances. A chemical substance is said to be symmetrical if its polar bonds are evenly distributed; it is described as unsymmetrical if its bonds are unequally distributed. In the compound BF3, the bond dipoles cancel one another out because the polar bonds are evenly distributed whereas in NF3, the bond dipoles were not able to cancel each other out because of unequal distribution of the polar bonds, the compound has a net dipole moment.

28.What is the correct IUPAC name for the following compound?A)12-crown-5B)12-crown-4C)4-crown-12D)12-crown-12E)Cyclododecane te
mariarad [96]

Answer:

12-crown-4

Explanation:

We must recall that any structural moiety in organic chemistry having the R-O-R unit is an ether. If the oxygen form a ring in which they are sandwiched in between carbon atoms, the compound is known as a crown ether. The name emanates from the close resemblance of the compound to an actual crown.

If we want to name the crown ether, we first count the number of carbon atoms present and the number of oxygen atoms present. The correct name is now, total number of carbon + oxygen atoms -crown- number of oxygen atoms, in this case; 12-crown-4, hence the answer.

An inverted pyramid is being filled with water at a constant rate of 45 cubic centimeters per second. The pyramid, at the top, h
vaieri [72.5K]

Answer:

13.20 cm/s is the rate at which the water level is rising when the water level is 4 cm.

Explanation:

Length of the base = l

Width of the base  =  w

Height of the pyramid = h

Volume of the pyramid = V=\frac{1}{3}lwh

We have:

Rate at which water is filled in cube = \frac{dV}{dt}= 45 cm^3/s

Square based pyramid:

l = 6 cm, w = 6 cm, h = 13 cm

Volume of the square based pyramid = V

V=\frac{1}{3}\times l^2\times h

\frac{l}{h}=\frac{6}{13}

l=\frac{6h}{13}

V=\frac{1}{3}\times (\frac{6h}{13})^2\times h

V=\frac{12}{169}h^3

Differentiating V with respect to dt:

\frac{dV}{dt}=\frac{d(\frac{12}{169}h^3)}{dt}

\frac{dV}{dt}=3\times \frac{12}{169}h^2\times \frac{dh}{dt}

45 cm^3/s=3\times \frac{12}{169}h^2\times \frac{dh}{dt}

\frac{dh}{dt}=\frac{45 cm^3/s\times 169}{3\times 12\times h^2}

Putting, h = 4 cm

\frac{dh}{dt}=\frac{45 cm^3/s\times 169}{3\times 12\times (4 cm)^2}

=13.20 cm/s

13.20 cm/s is the rate at which the water level is rising when the water level is 4 cm.
