How are the Solutions Presented in the TN Board Class 11 Solutions PDF Free

To get to know about an inside look at the solutions, let’s understand through an example. 

One of the chapters of the Physics subject is Nature of Physical World and Measurement, and if you open the TN Board Class 11 solutions PDF download, then you will find the following things - 

• Objective-type questions

• Short-answer type questions

Question: Define precision and accuracy. Explain with an example.

The answer is given with proper definitions and an example -

Ans: The accuracy of a measurement is a measure of how close the measured value is to the true value of the quantity. Precision of a measurement is the closeness of two or more measured values to each other.

The true value of a certain length is 5.678 cm. In one experiment, using a measuring instrument of resolution 0.1 cm, the measured value is found to be 5.5 cm. In another experiment using a measuring instrument of greater resolution, say 0.01 cm, the length is found to be 5.38 cm. We find that the first measurement is more accurate as it is closer to the true value, but it has less precision. On the contrary, the second measurement is less accurate, but it is more precise.

• Long-answer type questions

In the long-answer type questions, you will find a detailed explanation of the question in the Samacheer Kalvi 11th books solutions, along with the important terms and formulas. 

• Numerical Problems

In the numerical-based problems of the Samacheer Kalvi HSC +11 books solutions, you don’t need to focus on pointer explanations but need to apply the concept to the question. 

Question: In a submarine equipped with sonar, the time delay between the generation of a pulse and its echo after reflection from an enemy submarine is observed to be 80 sec. If the speed of sound in water is 1460 m s⁻¹. What is the distance of the enemy submarine?

Answer:

Given: Speed of sound in water = 1460 m s⁻¹
Time delay = 80 s
Distance of enemy ship =?

Solution: Total distance covered = speed × time

= 1460 m s⁻¹ × 80 s
= 116800 m

The time taken is for the forward and backward path of sound waves.

Distance of enemy ship = 58400 m (or 58.4 km).

Once you open the PDF of any subject, you will see this kind of question with answers, and it is important to first solve it yourself and then look over them.
