The Andhra Pradesh Board of secondary education was established in 1953 and is known for its quality education standards across country. It work as an autonomous body under the department of education. The head office of the board is in Hyderabad. It executes and supervise various activities like conducts exams, provides direction, support and leadership for the educational system. Here in this post you will find AP State Board 10th Class Question Papers of Physical Science, Solved paper for the purpose of providing help to the Board students of Andhra Pradesh. To enhance your practice in a more efficient way you can take help from Class 10th formulae of Maths.

Physical Science Question Papers

As a graduate, I have tried to set this AP State Board 10th Class Question Papers which is totally based on the syllabus. This effort has been made to help students so that they can practice their subject well before going for exam. All important topics of the Physical Science are covered in this paper. As the class 10 board exam is the first board exam for the students. So, by practising these sample papers students gain knowledge about the type of questions that may asked in the exam.

Instructions that must be followed by students while solving this Physical Science Question Papers are as follow:

1. This paper consists of two parts namely Part-A and Part-B
2. Part -A include four sections for time duration of 2 hours and 35 marks as total.
3. Part-B is for time duration 1/2 hour and contain 15 marks as total.
4. Marks are allotted to respective questions.

PART – A.                                          Time: 2 Hours PART- A Marks: 35

SECTION – I  

Note: Answer any  FIVE questions choosing at least TWO from each group. Each question carries TWO marks.

GROUP – A      5 * 2 = 10

1.What is simple harmonic motion? Write down its characteristics?
Ans: The to-and-fro motion of a particle about a mean position on a fixed path and position is called simple harmonic motion

2. A 1.5 V battery is connected across a bulb. Find the resistance of the filament if the current is 0.15?
Ans:By  Ohm’s law we have V=IR.
=>R=V\I
=>R=1.5.15=10Ω

3. What are Hardware and Software of a Computer?

GROUP – B

4. Distinguish between orbit and orbital.

5. What are the uses of Cold-Cream?
Ans:- Uses are as follows-

• Cold creams are used as cosmetics for skin.
• They protect the skin from hot sun, effect of cold breeze and dust.
• They clean the skin and make it feel smooth.
• A good quality cream melts at body temperature and spreads readily over the skin
•  It should not be sticky and greasy.

SECTION – II           

Note: Answer any FOUR. Each question carries ONE mark.    4 * 1 = 4

6. State Hooke’s Law.
Ans:- Within the elastic limit, stress is directly proportional to the strain.

7. What is a Spectrum?
Ans:- A group of wavelengths or frequencies is called a spectrum

8. Name the inert gases.
Ans:- Helium, Neon, Argon, Krypton, Xenon, Radon are inert gases.

9. What are the advantages of hydrogenation of oils?
Ans:- Hydrogenation of oils improves preservation, taste and odor of many oils.

SECTION – III  

Note: Answer any FOUR questions. Each question carries FOUR marks.   4 *4 = 16

10. Compare the properties of α, β and g radiations.

11. An electric installation of 100 lamps each drawing 0.2 amp current  at 220 V supply. Find the cost of working of installation for a month of 30 days at 5 hours per day, if the energy used costs at Rs. 2 per unit.
Ans:-Power P = V × I and
Electric energy E = P × t
=> P = 220 × 0.2 = 44 Watt
E for 100 lamps = 44 × 150 × 100 = 660 KWH = 660 Units.
Cost of 660 units = 660 × 2 = Rs. 1320

 12. State the properties and uses of Junction Transistor.
Ans:-

• A Junction transistor has two p-n Junctions
• In a circuit, one Junction of a transistor is forward biased and the other is reverse biased.
•  Less resistance is offered to the current flow in forward bias.
• A very high resistance is offered in the reverse bias junction.

 Uses:

• Transistor acts as an amplifier.
• Transistors are used as Oscillators.

Transistors are used in stabilized power supplies.

• Transistors are used in IC’s.
• Used in Chips.

GROUP – B

13. Define the terms:
a) Strong acid b) Weak acid c) Strong base d) Weak base.
Ans: a) Strong acid: The acid which is completely ionized (100%) is called strong acid.
e.g.: HCl, H₂SO₄, HNO₃

b) Weak acid: The acid which is incompletely ionized ( < 100%) is called weak acid.
e.g.: CH₃COOH, H₂CO₃, H₃PO₄

c) Strong base: The base which is completely ionized (100%) is called strong base. eg KOH, NaOH
d)Weak base:The base which is incompletely ionized(<100%)is called weak base. eg NH₃OH
