A ray passing through optical centre don't deviate ? why​

Physics
1 answer:
artcher [175]2 years ago
4 0

Answer:The middle part of the lens will just act as a rectangular glass slab. ... In thin lenses the perpendicular distance between extended incident ray and extended emergent ray is negligible. So this is why we can say that light ray passes through optical centre without deviation. I hope this helps you :)

A comet passes Earth over its equator. Pictures are taken of it from Earth's north and south poles simultaneously. In these pict
jok3333 [9.3K]

Answer:

Option B. 1,100 Earth diameters

Solution:

Angular position of steroid, \theta = 0.05^{\circ} = 8.726\times 10^{-4} radians                           (given)

To calculate the distance of asteroid, we use parallax method given as:

\theta = \frac{arc length(l)}{radius(R)}                 (1)

where,

From the relation:

l = \theta \times R

we get:

distance(d) or R = \frac{Earth diameter}{\theta}

distance(d) or R = \frac{2\times radius of earth}{\theta}

d = \frac{2\times 6350000}{8.726\times 10^{-4}}

distance, d = 1.455\times 10^{10} m

Comparing it with Earth's diameter:

d = \frac{1.455\times 10^{10}}{2\times 6350000} = 1,146

Since, the value is close to 1,100 Earth diameters, therefore, option B is the right answer.

-. What is the acceleration of 4 kg trolling bag pulled by a girl with a<br> force of 3 N?
PIT_PIT [208]

Answer:

Acceleration(a) = 0.75 m/s²

Explanation:

Given:

Force(F) = 3 N

Mass of thing(m) = 4 kg

Find:

Acceleration(a)

Computation:

Force(F) = ma

3 = (4)(a)

Acceleration(a) = 3/4

Acceleration(a) = 0.75 m/s²

Suppose you take two non-zero displacements represented by vectors A &amp; B.The magnitude of A is 5 m and the magnitude of B is
olga55 [171]

Answer:

a. When the total displacement is -(A + B)

b. A + B = 1 m or -(A + B) = -11 m

c. 0 m

Explanation:

a. Under what circumstances can you end up back at your starting point?

If we have the displacement A and displacement B. The total displacement is A + B. We would end up at the starting point if we take a displacement -(A + B) from point B

b. What is the magnitude of the largest displacement you can end up from the starting point?

The maximum displacement we can obtain is when A and B are in the same direction. So A + B = 5 m + 6 m = 11 m or -A - B = -(A + B) = -11 m.

c. When A and B are perpendicular, what is the component of B in the direction of A?

Since A is perpendicular to B, the angle between A and B is 90°

So the component of B in A,s direction is Bcos90° = B × 0 = 0 m
