The ability of a plant to detect the change and respond to that change is termed as the sensitivity of the plant. Yet plants have no nervous system and no muscle tissue, they use electrical and chemical means to convey the information from one cell to another cell. The leaves of the sensitive plant (Mimosa Pudica) folds up in response to touch. These leaf movements are independent of growth whereas, the directional movement of the shoot of a germinating seedling breaking through the soil is growth dependent.

The correct option is C) Virtual and inverted.

An astronomical telescope is an optical instrument which is used to see the magnified image of distinct heavenly bodies like stars, planets, satellites and galaxies etc. The final image formed by an astronomical telescope is always virtual, inverted and magnified. So, recently they saw lunar eclipse.

Correct option is  C) 60°

Given: F = 800 N, a = 5 m/s², u = 0, t = 10 s

To find: mass (m), distance travelled (s)

Formulae:

i. F = ma

ii. s = ut + \(\frac{1}{2}\)at²

Calculation:

From formula (i),

∴ m = \(\frac{F}{a}=\frac{800}{5}\) = 160 kg

From formula (ii),

s = \(\frac{1}{2}\) × 5 × (10)² [∵ u = 0]

∴ s = 250 m

Mass of the body is 160 kg and the distance travelled by the body is 250 m.

Two uses of convex lenses:- 

1. As a magnifying glass. 

2. For making a simple camera.

(a) focus. 

(b) object.

A) travel parallel to the principal axis

They converge at focus.

By placing another lens of suitable nature and focal length between the object and the screen.

The path of the rays is parallel to principal axis after refraction.

The answer is (b) less than unity

• Here the ray of light bends away from normal when it enters from medium A into medium B.
• This shows that medium B is optically rarer than medium A. 
• Therefore, speed of light in medium B is more than speed of light in medium A. 
• So, ratio of speed of light in medium A to speed of light in medium B will be less than one.

The answer is(a) A rectangular glass slab

• When incident rays fall perpendicularly on the point of incidence. 
• A rectangular glass slab would refract and then re-refract it.

(i) When light passes from water to air i.e., from denser to rarer its speed increases. 

(ii) Red light travels fastest.

Red colour is used as sign of danger due to its greater wavelength and lesser deviation (scattering). 

(c) Change in the intensity of illumination into a change in photoelectric current 

It indicates that threshold frequency is greater than that of ultraviolet light. As X-rays have greater frequency than uv rays, so they can cause photoelectric effect

The Correct option is (A)

A plane which is perpendicular to principal axis at the focus is called focal plane.

Every part of a lens forms a or complete image. If the lower part of the lens is blackened the complete image will be formed but its intensity will decrease.

Every part of a lens forms a complete image. If the lower part of the lens is blackened the complete image will be formed but its intensity will be decreased.

It depends on refractive index of the medium, object distance and image distance.

\(\frac {1}{f} = (n - 1) (\frac {1}{R_1}- \frac {1}{R_2})\)

(D) Metropolitan Area Network

(D) all the above

“Save” means the file gets saved under its current name, in whatever folder it was saved before or in the default folder of that computer whereas “Save As” gives you the opportunity to save the file under a different name and in another folder.

“Save As” allows you to name the updated version with a new name and at the same time preserving the old version.

Answer is (C) 20

A) how dense or sparse the vegetation is

Correct option is  C) Fullerene

(a) smallest

Sir, 

Sub: Not Receiving Medal at the Golden Gloves Championship Tournament Ref: Your Show Cause Notice dated 8 August 2005

I really regret the inconvenience I caused during the valedictory function of the Tournament. I do believe that in a game a contestant should fight well with true sportsman spirit rather than fight for a medal. I also believe that the value of a medal is not greater than the bond between human relationships. Please remember that my opponent was by closest friend.

I know that I won the match only because of my friend. He frightened me throughout the game. But in the last few minutes I faced only mild punches from him. He wanted me to win the match.

In the circumstances I may kindly be exempted from any disciplinary action.

your truly,

(Felix Vargas)

He asked Baucis to find some food for them.

(Here you can choose between the simple present and the present continuous tense.) It is remarkable how rapidly the country is developing. Progress is (being) made everywhere. In the town, old houses are (being) pulled down and new blocks of flats are (being) put up in their place. Large factories are (being) built within easy reach of the town. In these, only the most modern machinery is (being) installed. Good highways are (being)/have been constructed to connect one with another. In the countryside, too, a great deal has/ is to be done to increase agricultural production through new techniques. Irrigation schemes have/are to be introduced everywhere. In the south, large areas of land, which were once desert, have/are extensively been/being cultivated. It is a pleasure to see how much has been (is being) achieved through planning and hard work.

Daring Raid at Local Hotel 

The Manager of the Ridgeway Hotel was held at gunpoint by thieves last night during a daring raid in which nearly Rs. 50,000 was taken from the hotel safe. Several of the bedrooms also were broken into and articles of value were removed.

The thieves made their escape through the kitchen, where several pieces of equipment were damaged. The chef was injured when he tried to stop them and he was left lying unconscious on the oor. The thieves were arrested early this morning.

The boys ill-treated the strangers so Philemon said that the boys were bad.

1. This line is taken from the lesson “The wonder bowl”.

2. The lady was Baucis, the wife of Philemon

3. When Baucis said that if the strangers would have come little earlier, they could share their supper. At that moment the speaker said the above lines.

The strangers were pleased with their hospitality and their kindness. A small bowl of milk to drink was a feast for them.

After pouring the milk from the small bowl Into two cups, there is hardly a drop left in that bowl. One of the stranger took that bowl and filled not only his cup but also his friend’s with milk. Seeing this Baucis couldn’t believe her eyes. So she was astonished.

Lord Surya gave Akshaya Pathra to Yudhishtira

It would give unlimited food till Draupadi finished her meal.

1. ‘We’ stand for the old couple Philemon and Baucis.

2. It was said to the strangers, (angels).

3. The guests said that they were god’s messengers and pleased with the old couple’s kindness, and they should ask anything they like. So the speaker (asked) said the above lines.

1 The guests said the above line.

2. He said this to the old couple.

3. The speaker was pleased with the old couple’s kindness, and said so.

Durvasa and his disciples arrived in the house ofthe Pandavas.

Draupadi prayed for help.

The dogs barked at the strangers.

Krishna satisfied by eating a grain of rice. By his satisfaction he made Durvasa and all his disciples feel so fully fed.

If we have firm faith on someone or something (god, gum), the help will arrive definitely without any doubt.

No, they would never let any stranger who came to their doors go without food.

Live in it as long as you desire and you come to heaven together.

There is milk in this bowl much as we want,

They welcomed the guests with Joy.
