Separation of light into color is known as "Dispersion".

<u>Explanation: </u>

There presents a "collection of component colors in white light" which is also known as visible light.
The white light is passed through the prism and it is divided into Red, Green, orange, blue, violet and yellow colors.
Dispersion is the process of separation of light into different colors.
This phenomenon of Dispersion of White light was discovered by "Isaac Newton in 1666".

A flywheel is a solid disk that rotates about an axis that is perpendicular to the disk at its center. Rotating flywheels provid

Sergeeva-Olga [200]

Answer:

$8.37*10^5$ rpm

Explanation:

Given that rotational kinetic energy = $4.66*10^9J$

Mass of the fly wheel (m) = 19.7 kg

Radius of the fly wheel (r) = 0.351 m

Moment of inertia (I) = $\frac{1}{2} mr ^2$

Rotational K.E is illustrated as $(K.E)_{rt} = \frac{1}{2} I \omega^2$

$\omega = \sqrt{\frac{2(K.E)_{rt}}{I} }$

$\omega = \sqrt{\frac{2(KE)_{rt}}{1/2 mr^2} }$

$\omega = \sqrt{\frac{4(K.E)_{rt}}{mr^2} }$

$\omega = \sqrt{\frac{4*4.66*10^9J}{19.7kg*(0.351)^2} }$

$\omega = 87636.04$

$\omega = 8.76*10^4 rad/s$

Since 1 rpm = $\frac{2 \pi}{60} rad/s$

$\omega = 8.76*10^4(\frac{60}{2 \pi})$

$\omega = 836518.38$

$\omega = 8.37 *10^5 rpm$

Suppose a 10 mL beaker and a 100 mL beaker are both filled with water, and that the water in both beakers is the same temperatur

Doss [256]

The correct choice is

b. the larger beaker of water contains more heat than the smaller beaker

Reason :

Heat is given as

Q = m c T

where Q = heat contained

m = mass of water

c = specific heat of water

T = change in temperature.

since the specific heat and temperature is same for both the beakers, we need to look at which beaker contains more amount of water. the larger beaker has more mass of water, hence heat contained in the larger beaker is greater.

jenyasd209 [6]

Answer:

Explanation:

We shall use Ampere's circuital law to find magnetic field at required point.

The point is outside the circumference of two given wires so whole current will be accounted for .

Ampere's circuital law

B = ∫ Bdl = μ₀ I

line integral will be over circular path of radius r = 41 cm .

Total current I = 5A -3A = 2A .

∫ Bdl = μ₀ I

2π r B = μ₀ I

2π x .41 B = 4π x 10⁻⁷ x 2

B = 2 x 10⁻⁷ x 2 / .41

= 9.75 x 10⁻⁷ T . It will be along - ve Y - direction.
