Calculate the potential required to push eleven amperes through a 20 ohm resistance

den301095 [7]

Answer:

The answer is 220

Explanation:

Volts = current × resistance

Current = 11

Resistance = 20

Volts = 11 × 20

= 220

poizon [28]

Answer:

By calculation, it can be shown that;

K = $\frac{F_{angular}}{2\times x\times c}$

Whereby for constant K, as ${F_{angular}}$ increases, x also increases.

Explanation:

The experiment set up consisted of the use of a spring force to maintain the object in circular path.

The energy in the spring is given by

$\frac{1}{2}\cdot k\cdot x^2$ .

Rotational kinetic energy = $\frac{1}{2}$ ·I·ω²

Inertia, I = $\frac{1}{2}$ ·m·r²

ω = $\frac{v}{r}$

Substituting gives

Rotational kinetic energy = $\frac{1}{2}$ ·

= $\frac{1}{4}$ ·m· v²

Equating both equations gives

K = $\frac{2\times m\times v^2}{4\times x^{2} }$ = $\frac{1\times m\times v^2}{2\times x^{2} }$

Within the proportionality limit, x ∝ r

therefore we can write x = c·r which gives

$\frac{ m\times v^2}{2\times x\times c\times r }$ = $\frac{v^{2} }{r} \times\frac{m}{2\times x\times c}$

Since $\frac{v^{2} }{r}$ = angular acceleration, α, then

m× $\frac{v^{2} }{r}$ = Angular force

Therefore K = $\frac{F_{angular}}{2\times x\times c}$

Therefore as Force, F increases, x also increases and the size of a spring force should be proportional to the amount of stretch in the spring.

Elabora una tabla, como la del ejemplo, con los resultados obtenidos en los test que desarrollaste en actividades anteriores. Lu

rodikova [14]

Explanation:

Clear rendering reads;

"Make a table, like the one in the example, with the results obtained in the tests you carried out in previous activities. Then answer: What do these results indicate regarding your physical condition and how do they relate to your health? From your answers, consider the challenge of improving your physical condition by maintaining or improving your exercise routine or permanent practice of physical activity".

So the incomplete text above it seems you've been instructed to perform an experiment and then state your result/analysis.
