A 5.6 V battery is connected in series with a 41 mH inductor, a 100 Ω resistor, and an open switch. At what time after the switc
Vinil7 [7]

The current in a direct current resistor inductor circuit is given by:

i(t) = (-ℰ/R)e^{-Rt/L} + ℰ/R

Where i(t) is the current, t is time, ℰ is the battery's terminal voltage, R is the resistor's resistance, and L is the inductor's inductance.

Given values:

ℰ = 5.6V

R = 100Ω

L = 4.1×10⁻²H

Plug in the values to get i(t):

i(t) = -0.056e^{-2440t} + 0.056

We want to calculate when the current is 0.012A, i.e. find a time t when i(t) = 0.012A. So let us set i(t) equal to 0.012 and solve for t:

-0.056e^{-2440t} + 0.056 = 0.012

0.056e^{-2440t} = 0.044

e^{-2440t} = 0.786

-2440t = ㏑(0.786)

t = -㏑(0.786)/2440

t = 9.87×10⁻⁵s

Two planets X and Y travel counterclockwise in circular orbits about a star, as seen in the figure. The radii of their orbits ar
Korvikt [17]

By 272.7 degrees angle has planet Y rotated through during this time.

<h3 /><h3>What is Kepler's 3rd law?</h3>

The cubes of the semi-major axes of the planets' orbits are precisely proportional to the squares of the planets' orbital periods. According to Kepler's Third Law, as an orbiting planet's radius rises, so does the time of its orbit around the Sun.

Using Kepler's 3rd law, which says that the period of any planet's orbit squared is proportional to the radius of the orbit cubes, we can establish that

(period X / period Y)^2 = (radius X / radius Y)^3

(period X / period Y)^2 = 2^3 = 8

take sq root

period X / period Y = √8 = 2.82≅ 3

this means it takes planet X 2.82≅ 3  times longer to go through one orbit... so planet Y travels 2.82≅ 3  times as far (in its orbit...) as planet X!

This means...

planet Y travels   3 * 90.9  =   272.7 degrees

What are the factors that affect ocean density?<br><br> Please help!!
Paul [167]

The density of seawater plays a vital role in causing ocean currents and circulating heat because of the fact that dense water sinks below less dense. long story short, seawater is the problem because its denser than pure water.
