Answer:

If all the heat energy contained in a body is removed and changes in its temperature is described below in detail.

Explanation:

It moves from a body at a greater temperature to a body at a cheaper temperature. All element survives as solids, liquids, or gases. The material can transfer from one station to another if warmed or cooled. When heat is provided to a body its heat increases: When a physical body, hard, liquid. When heat is provided is stopped to a body its temperature decline.

One of the factors that determines the ? of a capacitor is the frequency measured in hertz.

ycow [4]

Answer:

Reactance

Explanation:

In an AC circuit, the capacitive reactance of a capacitor is given by:

$X_C = \frac{1}{2 \pi f C}$

where

f is the frequency of the AC current

C is the capacitance of the capacitor

The reactance of the capacitor tells somehow the "resistance" of the capacitor to the passage of current through it. In fact:

- When the frequency of the AC current is zero (this means, we are in regime of DC current), the reactance becomes infinite, and this is true because the capacitor does not let the current pass through it)

- When the frequency of the AC current tends to infinite, the reactance becomes zero, and this is true because in this case the current changes direction so fast that the capacitor has not enough time to "block" the current, so the current almost no feels the presence of the capacitor.

For a certain optical medium the speed of light varies from a low value of 1.90 × 10 8 m/s for violet light to a high value of 2

Dmitry_Shevchenko [17]

Answer:

a. The refractive index ranges from 1.5 - 1.56

b. 18.7° for violet light and 19.5° for red light.

c. 33.7° for violet light and 35.3° for red light.

Explanation:

a. The refractive index of an object is the ratio of the speed of light in a vacuum and the speed of light in the object.

Mathematically,

$n = \frac{c}{v}$

The speed of violet light in the object is $1.9 * 10^8 m/s$ .

The speed of red light in the object is $2 * 10^8 m/s$

Hence, the refractive index for violet light is:

$n = \frac{3 * 10^8 }{1.9 * 10^8} \\\\n = 1.56$

and for red light, it is:

$n = \frac{3 * 10^8 }{2 * 10^8} \\\\n = 1.5$

Hence, the refractive index ranges from 1.5 - 1.56.

b. The refractive index is also the ratio of the sine of the angle of incidence to the sine of the angle of refraction.

$n = \frac{sin(i)}{sin(r)}$

The angle of incidence is 30°.

The angle of refraction for violet light will be:

$1.56 = \frac{sin(30)}{sin(r)}\\ \\sin(r) = \frac{sin(30)}{1.56} = \frac{0.5}{1.56} \\\\sin(r) = 0.3205\\\\r = 18.7^o$

And the angle of refraction for red light will be:

$1.5 = \frac{sin(30)}{sin(r)}\\ \\sin(r) = \frac{sin(30)}{1.5} = \frac{0.5}{1.5} \\\\sin(r) = 0.3333\\\\r = 19.5^o$

The angle of refraction for red light is larger than that of violet light when the angle of incidence is 30°.

c. The angle of incidence is 60°.

The angle of refraction for violet light will be:

$1.56 = \frac{sin(60)}{sin(r)}\\ \\sin(r) = \frac{sin(60)}{1.56} = \frac{0.8660}{1.56} \\\\sin(r) = 0.5551\\\\r = 33.7^o$

And the angle of refraction for red light will be:

$1.5 = \frac{sin(60)}{sin(r)}\\ \\sin(r) = \frac{sin(60)}{1.5} = \frac{0.8660}{1.5} \\\\sin(r) = 0.5773\\\\r = 35.3^o$

The angle of refraction for red light is still larger than that of violet light when the angle of incidence is 60°.

Find the acute angles between the curves at their points of intersection. (The angle between two curves is the angle between the

ladessa [460]

Answer:

1.190390345 degrees.

Explanation:

As stated in the problem that the angle between the two curves is also the angle between slopes of the two cures at the point of intersection, which is 1 (when we set two equation equal and solve for x).

We know, if you don't you could verify it for yourself and it will be a nice mathematical exercise for you, that when there are two lines with slopes $m_1$ and $m_2$ then the angle between them and their two slopes has following relationship.

$tan(\alpha ) = |\frac{m_2-m_1}{1+m_1m_2}|$ where $\alpha$ is angle between the two lines.

As it is clear that we can easily get the angle between the two curves if we know slopes at that point, which you will see in second is very straight forward to calculate.

Slopes are simply derivatives evaluated at the point of intersection and the two derivatives are $D_1$ 16x and $D_2 =24x^2$ , substituting x =1 we get, $m_1 = 16$ and $m_2 = 24$ .

Now put $m_1$ and $m_2$ in this relationship, rearrange and solve for angle, it will come out to be

$\alpha$ = 1.190390345 degrees.

that is our angle that we want to know between the two cures at the point of their intersection.
