A current of 0.3 ampere flows through a 2-ohm resistor. At what rate does the resistor release heat?

beks73 [17]

Answer:

D. 018 W

Explanation:

Power = current × voltage

P = IV

From Ohm's law, voltage = current × resistance

V = IR

Therefore:

P = I²R

Given I = 0.3 A and R = 2 Ω:

P = (0.3 A)² (2 Ω)

P = 0.18 W

Identify the true statements about the relationship between the distillate and the sample mixture in a simple distillation.

fenix001 [56]

Answer:

The answer is "Choice b,c, and d".

Explanation:

The distillation would be the separation phase of working liquids that boil close to each other. Whenever the formulation is long-term, a much more fraction of a compound collected will have a lower boiling point than it would otherwise be. In other phrases, it'll be pulverized with both the lower level, also with the boiling point. Its structure of both the diluted volatile component may therefore include another cell's contaminants.

In a tension test of steel, the ultimate load was 13,100 lb and the elongation was 0.52 in. The original diameter of the specime

vivado [14]

Answer:

a) the ultimate tensile stress is 66717.8 psi

b) the ductility of the material in terms of percent elongation is 26%

Explanation:

Given the data in the question;

ultimate load P = 13,100 lb

elongation δl = 0.52 in

diameter of specimen d = 0.50 in

gage length l = 2.00 inch

First we determine the cross-sectional area of the specimen

A = $\frac{\pi }{4}$ × d²

we substitute

A = $\frac{\pi }{4}$ × ( 0.50 )²

A = 0.1963495 in²

a) the ultimate tensile stress σ $_u$

tensile stress σ $_u$ = P / A

we substitute

tensile stress σ $_u$ = 13,100 / 0.1963495

tensile stress σ $_u$ = 66717.766 ≈ 66717.8 psi

Therefore, the ultimate tensile stress is 66717.8 psi

b) ductility of the material in terms of percent elongation;

percentage elongation of specimen = [change in length / original length]100

% = [ δl / l ]100

we substitute

% = [ 0.52 in / 2.00 in ]100

= [ 0.26 ]100

= 26

Therefore, the ductility of the material in terms of percent elongation is 26%
