Answer:

You are asked to design a cylindrical steel rod 50.0 cm long, with a circular cross section, that will conduct 170.0 J/s from a furnace at 350.0 ∘C to a container of boiling water under 1 atmosphere.

Explanation:

Given Values:

L = 50 cm = 0.5 m

H = 170 j/s

To find the diameter of the rod, we have to find the area of the rod using the following formula.

Here Tc = 100.0° C

k = 50.2

H = k × A × $\frac{[T_{H -}T_{C} ] }{L}$

Solving for A

A = $\frac{H * L }{k * [ T_{H}- T_{C} ] }$

A = $\frac{170 * 0.5}{50.2 * [ 350 - 100 ]}$

A = $\frac{85}{12550}$ = 6.77 × $10^{-3}$ m²

Now Area of cylinder is :

A = $\frac{\pi }{4}$ d²

solving for d:

d = $\sqrt{\frac{4 * 0.00677 }{\pi } }$

d = 9.28 cm

Which property help to explain differences in the specific heat capabilities of two substances

OLga [1]

Answer:

Forces between molecules

Explanation:

The tensions between molecules are the characteristic that explains variances in the specific heat capacity of two substances.

This means that a substance's specific heat capacity will increase or be higher the closer its atoms are bound together. As a result, it differs for the different states of matter, such as solid, liquid, and gas.

In a long straight wire, what current is required to exert a 1.0μN force on a 1.0μC charge moving at 1.5×106m/s parallel to the

Bas_tet [7]

Answer:

Current in the wire is given as

$i = 1.17 \times 10^{-7} A$

Explanation:

magnetic field due to long current carrying wire is given as

$B = \frac{\mu_0 i}{2\pi r}$

so we have magnetic force on moving charge is given as

$F = qvB$

so we have

$F = (1\times 10^{-6})(1.5 \times 10^6)(\frac{\mu_0 i}{2\pi (0.35)})$

so we have

$1\times 10^{-6} = 1.5 \times \frac{2 i}{0.35}$

$i = 1.17 \times 10^{-7} A$

A bank offers a credit plan that lists 2% interest for the first year of a loan. If a customer takes the loan and 16 years later

Bumek [7]

If the interest rate hasn't changed over the course of 16 years,
then that's pretty convincing evidence to suggest that the loan
has an fixed rate.
