Why would an counductor heat up soup?

1 answer:

6 0

example of a great insulator is a thermos. If you put soup in a thermos, you can open it later and enjoy warm soup on a cold winter day. The thermos insulates the soup, trapping the heat inside. Likewise, if you are playing soccer on a hot August afternoon, your thermos full of ice water stays refreshing and cold.

What are the differences between balloon framing and platform framing? What are the advantages and disadvantages of each? Why ha

Licemer1 [7]

Answer:

Difference : Balloon framing go through from foundation to top floor while Platform do not

advantages and disadvantages

Balloon framing : It has less vertical shrinkage ( disadvantage )

platform framing : It has more vertical shrinkage and fire stops ( advantage )

platform framing : It is easier and safer to use

Reason for platform framing :

Due to these advantages Platform framing has become a better choice

Little added fire stopping is required in platform framing because of double tap plate present which can act as as a fire stop

Steel beam/ glue laminated wood beam is preferred at foundation level because wood beam under the ground will most likely shrink over time

Explanation:

Differences : Balloon framing a form of building houses using a special kind of timber construction its studs start from the foundation and go to all the way to the last floor while in Platform framing the studs are interrupted by floor platforms ( i.e. they do not go through like in Balloon framing )

What is the magnitude of the magnetic field at a point midway between them if the top one carries a current of 19.5 A and the bo

Phantasy [73]

Answer:

The magnetic field will be $\large{\dfrac{1.4 \times 10^{-4}}{d}} T$ , '2d' being the distance the wires.

Explanation:

From Biot-Savart's law, the magnetic field ( $\large{\overrightarrow{B}}$ ) at a distance ' $r$ ' due to a current carrying conductor carrying current ' $I$ ' is given by

$\large{\overrightarrow{B} = \dfrac{\mu_{0}I}{4 \pi}} \int \dfrac{\overrightarrow{dl} \times \hat{r}}{r^{2}}}$

where ' $\overrightarrow{dl}$ ' is an elemental length along the direction of the current flow through the conductor.

Using this law, the magnetic field due to straight current carrying conductor having current ' $I$ ', at a distance ' $d$ ' is given by

$\large{\overrightarrow{B}} = \dfrac{\mu_{0}I}{2 \pi d}$

According to the figure if ' $I_{t}$ ' be the current carried by the top wire, ' $I_{b}$ ' be the current carried by the bottom wire and ' $2d$ ' be the distance between them, then the direction of the magnetic field at 'P', which is midway between them, will be perpendicular towards the plane of the screen, shown by the $\bigotimes$ symbol and that due to the bottom wire at 'P' will be perpendicular away from the plane of the screen, shown by $\bigodot$ symbol.
