Q1. A student measures the time period of a simple pendulum. According to the physics of the pendulum, its time period depends on which of the following?
▸ Show answer & explanation
Answer: A
For small oscillations the time period $T = 2\pi\sqrt{\frac{L}{g}}$ depends only on length L and gravity g, not on the mass of the bob.
Q2. Rickets, a disease causing soft and bent bones in children, results mainly from a deficiency that impairs calcium absorption. Which vitamin's deficiency causes rickets?
▸ Show answer & explanation
Answer: A
Vitamin D promotes calcium and phosphorus absorption needed for bone mineralisation; its deficiency causes rickets in children.
Q3. Which blood cells are primarily responsible for transporting oxygen from the lungs to the tissues of the body?
▸ Show answer & explanation
Answer: A
Red blood cells contain haemoglobin, which binds oxygen in the lungs and carries it to body tissues. White cells fight infection and platelets aid clotting.
Q4. Insulin, a hormone that regulates blood sugar levels, is secreted by which organ?
▸ Show answer & explanation
Answer: A
Insulin is secreted by the beta cells of the islets of Langerhans in the pancreas and lowers blood glucose levels.
Q5. The atomic number of an element is defined as the number of:
▸ Show answer & explanation
Answer: A
The atomic number equals the number of protons in the nucleus, which defines the element's identity. Protons plus neutrons gives the mass number.
Q6. A pressure cooker cooks food faster at high altitudes mainly because it raises the boiling point of water by trapping steam. Which physical quantity is directly responsible for this increase in boiling point inside the cooker?
▸ Show answer & explanation
Answer: A
Trapped steam raises the internal pressure, and a higher pressure raises the boiling point of water, allowing food to cook at a temperature above 100°C.
Q7. The chemical formula of common table salt is NaCl. Which pair of elements combines to form this compound?
▸ Show answer & explanation
Answer: A
Table salt, sodium chloride (NaCl), is formed by the combination of the metal sodium (Na) and the non-metal chlorine (Cl).
Q8. Goitre, a swelling of the neck due to an enlarged thyroid gland, is most directly caused by the dietary deficiency of:
▸ Show answer & explanation
Answer: A
The thyroid needs iodine to make thyroid hormones; iodine deficiency causes the gland to enlarge, producing goitre.
