Few questions from CBSE Class 11 Maths Sample Paper 2019 are given below:

**Question:**

If A = {1, 2, 3, 6}, B = {3, 4, 5, 7} and C = {4, 6, 7, 8}; find A ∪ B ∪ C.

**Solution:**

Given: A = {1, 2, 3, 6}, B = {3, 4, 5, 7} and C = {4, 6, 7, 8}

In union we write all elements of both sets without repeating.

Therefore, A ∪ B ∪ C = {1, 2, 3, 4, 5, 6, 7, 8}

**Question:**

Find the equation of the line that cuts off equal intercepts on the coordinate axes a passes through the point (4, 5).

**Solution:**

Equation of a line in intercept form is

**CBSE Sample Paper 2019 for Class 11 Physics**

Physics is an application based subject. Students should try to clear all their basic concepts before attempting any numerical questions. Students can score good marks if they try to understand the concepts instead of rote learning. There are 27 questions in CBSE Class 11 Sample Paper of Physics which are divided into four sections namely A, B, C and D.

**CBSE Class 11 Physics NCERT Solutions: All Chapters**

Few questions from CBSE Class 11 Physics Sample Paper 2019 are given below:

**Question:**

Does short-sightedness (myopia) or long-sightedness (hypermetropia) imply necessarily that the eye has partially lost its ability of accommodation? If not, what might cause these defects of vision?

**Solution:**

No, a myopic or hypermetropic person may have normal ability of accommodation of the eye lens. The partial loss of ability of accommodation of eye lens is called presbyopia. It can be corrected in the way hypermetropia is dealt with.

**Question:**

What are laws of limiting friction?

**Solution:**

The laws of limiting friction are as follows:

(i) The magnitude of the force of limiting friction (F) between any two bodies in contact is directly proportional to the normal reaction (R) between them i.e. F ∝ R.

(ii) The direction of the force of limiting friction is always opposite to the direction in which one body is at the verge of moving over the other.

(iii) The force of limiting friction is independent of the apparent area of contact, as long as the normal reaction between the two bodies in contact remains same.

(iv) The force of limiting friction between any two bodies in contact depends on the nature of material of the surfaces in contact and their roughness or smoothness.

**CBSE Class 11 Biology NCERT Solutions: All Chapters**

Few example questions from CBSE Class 11 Biology Sample Paper 2019 are given below:

**Question:**

What are respiratory substrates? Name the most common respiratory substrate.

**Solution:**

In the process of respiration, those compounds which get oxidised to release energy are called respiratory substrates. The most common respiratory substrate is glucose.

**Question:**

Explain with suitable examples the different types of phyllotaxy?

**Solution:**

Phyllotaxy refers to the pattern or arrangement of leaves on the stem or branch of a plant. There are three types of phyllotaxy which are described as below:

(i) **Alternate phyllotaxy:** In this type of phyllotaxy, a single leaf arises from each node of a branch in alternate manner. For example: Sunflower, mustard, and China rose.

(ii) **Opposite phyllotaxy:** Plants with opposite phyllotaxy have a pair of leaves arising from each node and both lie in opposite direction to each other. For example: Guava and jamun plants.

(iii) **Whorled phyllotaxy:** In this type of phyllotaxy, more than two leaves arise from each node forming a whorl. For example: Alstonia.
