Answer:

The rms current in the circuit is 3.513 A

Explanation:

Given;

angular frequency of the inductor, ω = 363 rad/s

maximum voltage of the inductive AC, V₀ = 169 V

Inductance of the inductor, L = 0.0937 H

Inductive reactance is given by;

X_L = 2\pi f L= \omega L

X_L = 363 *0.0937\\\\X_L = 34.0131 \ ohms

The rms voltage is given by;

V_{rms} = \frac{V_o}{\sqrt{2} } \\\\V_{rms} =\frac{169}{\sqrt{2} } \\\\V_{rms} = 119.5 \ V

The rms current in the circuit is given by;

I_{rms} = \frac{V_{rms}}{X_L} \\\\I_{rms} = \frac{119.5}{34.0131} \\\\I_{rms} = 3.513 \ A

Therefore, the rms current in the circuit is 3.513 A

One advantage of the hubble space telescope over ground based ones is that
vladimir1956 [14]

Space telescopes have the advantage of being above the blurring effects of the Earth's atmosphere.

A surrounding is a layer of fuel or layers of gases that envelop a planet and is held in a region through the gravity of the planetary frame. A planet retains its surroundings whilst the gravity is exceptional and the temperature of the surroundings is low. A stellar ecosystem is the outer area of a celeb, which includes the layers above the opaque photosphere; stars of low temperature may have outer atmospheres containing compound molecules.

The atmosphere of Earth consists of nitrogen (78%), oxygen (21%), argon (0.9%), carbon dioxide (0.04%), and trace gases. most organisms use oxygen for breathing; lightning and bacteria perform nitrogen fixation to provide ammonia that is used to make nucleotides and amino acids; flora, algae, and cyanobacteria use carbon dioxide for photosynthesis.

The layered composition of the ecosystem minimizes the damaging results of daylight, ultraviolet radiation, solar wind, and cosmic rays to defend organisms from genetic harm. The modern composition of the atmosphere of the Earth is made from billions of years of biochemical modification of the paleo atmosphere by residing organisms.

What is the boiling point of an aqueous solution that freezes at -2.05 degrees C? Kfp = 1.86 K/m and Kbp = 0.512 K/m. Enter your
prisoha [69]

To solve this problem we will apply the concepts of Boiling Point elevation and Freezing Point Depression. The mathematical expression that allows us to find the temperature range in which these phenomena occur is given by

Boiling Point Elevation

\Delta T_b = K_b m

Here,

K_b = Constant ( Different for each solvent)

m = Molality

Freezing Point Depression

\Delta T_f = K_f m

Here,

K_f = Constant ( Different for each solvent)

m = Molality

According to the statement we have that

\Delta T_f = T_0 -T_f = 0-(-2.05)

\Delta T_f = 2.05\°C

From the two previous relation we can find the ratio between them, therefore

\frac{\Delta T_b}{\Delta T_f} = \frac{K_b}{K_f}

\frac{\Delta T_b}{\Delta T_f} = \frac{0.512}{1.86}

\frac{\Delta T_b}{\Delta T_f} = 0.275

We already know the change in the freezing point, then

\Delta T_b = 0.275 (\Delta T_f)

\Delta T_b = 0.275 (2.05)

\Delta T_b = 0.5643\°C

The temperature difference in the boiling point is 100°C (Aqueous solution), therefore

T_b -100 = 0.5643

T_b = 100.56\°C

Therefore the boiling point of an aqueous solution is 100.56\°C
