1303.	The two spreed of light on glasss in 2× 10 ^5 what is the ri of glass
Answer» Answer: The speed of LIGHT in AIR is c = 3 × 108 m/s. Thus, the speed of light in GLASS will be given as. v = c/n = 3 × 108/ 1.5 = 2 × 108 m/s. The speed, wavelength and frequency are related as. c = νλ Thus, wavelength in air is given as. λa = c/ν = 3 × 108/ 6 × 1014 = 5 × 10-7 m.

1303.

The two spreed of light on glasss in 2× 10 ^5 what is the ri of glass

Answer»

Answer:

The speed of LIGHT in AIR is c = 3 × 108 m/s.

Thus, the speed of light in GLASS will be given as.

v = c/n = 3 × 108/ 1.5 = 2 × 108 m/s.

The speed, wavelength and frequency are related as.

c = νλ

Thus, wavelength in air is given as.

λa = c/ν = 3 × 108/ 6 × 1014 = 5 × 10-7 m.

Answer» EXPLANATION: The telescope is used to provide angular magnification of distant objects. The objective has a large focal length and a much larger aperture than the eyepiece because object is very far away. ... This image acts as an object for the eyepiece; it magnifies this image producing a final INVERTED Telescope, device used to form magnified images of distant objects. The telescope is undoubtedly the most important investigative tool in astronomy. It provides a means of collecting and ANALYZING radiation from celestial objects, even those in the far reaches of the universe. Most refracting telescopes use two main lenses. The largest lens is called the objective lens, and the smaller lens used for viewing is called the eyepiece lens. Primary mirror (for reflecting telescopes), which carries the same role as the primary lens in a refracting telescopes. Eyepiece, which magnifies the image. Mounting, which supports the tube, enabling it to be ROTATED. Telescopes can be divided into two main CATEGORIES: refractors and reflectors.

the work done in turning a magnet of magnetic moment m by an angle of 90 degree from the Mediterranean is N times the corresponding work done to turn it through an angle of 60 degree the value of n is given by

Answer»

Q]____?

EXPLANATION:

WORK done in rotating a dipole from θ1 to θ2 is

W = - MB ( cos θ2 - cos θ1 )

[ M = Magnetic moment

B = Magnetic induction ]

CASE I

W1 = MB ( cos 60° - cos0° ) = MB _[i]

CASE II

W2 = - MB ( cos 60° - cos 0° )

W2 = - MB [ 1/2 - 1 ] = 1/2 MB _[ii]

From EQS [i] and [ii] W2 = 1/2 W1

As W1 = nW2

∴ N = 2

∴ The value of n is 2 !

- A man swims across a river with speed of 5 kmh (in still water), while a boat goes upstreamwith speed 12 km h' (in still water). How fast and in which direction does the man appear to goto the boatman? Given that the speed of flowing water is 2 km hr!

Answer»

The velocity of boat with respect to river

=> Vb = √(2)² + (12)²

=> Vb = √128 m/s

The RELATIVE velocity of man with respect to river

=> VM = √(2)² + (5)²

=> Vm = √29 m/s

The DIRECTION in which the man appear to GO to the boatman

$= > theta = \cos ^{ - 1} ( \frac{vm}{vb}) \\ = > theta = \cos ^{ - 1}( \sqrt{ \frac{29}{148}) }$

The speed with which man should MOVE faster

$v \: = \sqrt{148 - 29}$

V = √119 km/hr

1346.	A physical quantity X is given by X = A B3/C D1/2. If the percentage errorsof measurement in A, B, C and D are 4% ,2%,3% and 1% respectively, then calculate the % error in X.
Answer» % error in X = 13.5%. . Explanation: X = AB³/CD½ ∆X/X = ∆A/A + 3(∆B/B) +∆C/C + 1/2(∆D/D) percentage ERRORS are (∆X/X) x100= (∆A/A) x 100 + 3(∆B/B)x 100+(∆C/C) x 100 + 1/2(∆D/D) x 100 = 4 + (3x2) + 3 + (1/2 x 1) = 13 + 1/2 = 27/2 % = 13.5 ℅

A physical quantity X is given by X = A B3/C D1/2. If the percentage errorsof measurement in A, B, C and D are 4% ,2%,3% and 1% respectively, then calculate the % error in X.

Answer»

% error in X = 13.5%. .

Explanation:

X = AB³/CD½

∆X/X = ∆A/A + 3(∆B/B) +∆C/C + 1/2(∆D/D)

percentage ERRORS are

(∆X/X) x100= (∆A/A) x 100 + 3(∆B/B)x 100+(∆C/C) x 100

+ 1/2(∆D/D) x 100

= 4 + (3x2) + 3 + (1/2 x 1)

= 13 + 1/2

= 27/2 %

= 13.5 ℅
