Which reactance will increase when the angular frequency in the circuit increases?

1 answer:

5 0

The inductive reactance increases as the angular frequency of the circuit increases. We can primarily use the formula for finding the inductive inductance as our main basis:

Xl = 2*pi*f*L

where Xl is the inductive reactance, and f is the angular frequency

We can conclude from the given equation that the inductive reactance and angular frequency are directly proportional to one another.

Relating the circumference to the force applied on the balloon, make a conclusion on the relationship of force to the rate of th

natka813 [3]

At a constant force, the mass of the balloon is inversely proportional to the rate of change motion of the balloon.

The force applied to an object can be determined by applying Newton's second law of motion, the force applied to an object is directly proportional to the product of mass and acceleration of the object.

F = ma

where;

<em>m is the mass of the balloon</em>
<em>a is the change in velocity per time</em>

$F = m\frac{\Delta v}{t} \\\\\frac{F}{\frac{\Delta v}{t}} = m$

The mass of an object is inversely proportional to the rate of change motion of the object.

Thus, we can conclude that at constant force, the mass of the balloon is inversely proportional to the rate of change motion of the balloon.

In a physics lab, light with a wavelength of 490 nm travels in air from a laser to a photocell in a time of 17.5 ns . When a sla

Gennadij [26K]

Answer:

196 nm

Explanation:

Given that

Value of wavelength, = 490 nm

Time spent in air, t(a) = 17.5 ns

Thickness of glass, th = 0.8 m

Time spent in glass, t(g) = 21.5 ns

Speed of light in a vacuum, c = 3*10^8 m/s

To start with, we find the difference between the two time spent

Time spent on glass - Time spent in air

21.5 - 17.5 = 4 ns

0.8/(c/n) - 0.8/c = 4 ns

Note, light travels with c/n speed in media that has index of refraction

(n - 1) * 0.8/c = 4 ns

n - 1 = (4 ns * c) / 0.8

n - 1 = (4*10^-9 * 3*10^8) / 0.8

n - 1 = 1.2/0.8

n - 1 = 1.5

n = 1.5 + 1

n = 2.5

As a result, the wavelength of light in a medium with index of refraction would then be

490 / 2.5 = 196 nm

Therefore, our answer is 196 nm
