Answers :

1). Answer: C

Telephoto lenses compress space, making people and objects that are far apart appear really near one another. If a filmmaker is shooting a scene on the freeway where actors have to run among speeding vehicles, telephoto lenses can be a safe method to keep actors distant from danger while still selling the illusion that the talent is just a few feet away from moving cars.

2). Answer: C

The mole is the only fundamental SI unit that is dimensionless.

3). Answer: D

Wide-angle lenses are the opposite of telephoto. Wide-angle lenses have a broader field of view, and therefore they can show sweeping panoramas of mountains, oceans, and forests. Since camera jiggle is negligible with wide-angle, this choice of lens is ideal for handheld work.

4). Answer: B

A wind turbine is a device that converts kinetic energy from the wind into electrical power. A wind turbine used for charging batteries may be referred to as a wind charger.

5). Answer: B

Cobalt 60 is used to external radiation therapy for treatment of cancer.

6). Answer: B

Uranium–lead dating, abbreviated U–Pb dating, is one of the oldest and most refined of the radiometric dating schemes. It can be used to date rocks that formed and crystallized from about 1 million years to over 4.5 billion years ago with routine precisions in the 0.1–1 percent range.

7). Answer: D

Pepsin is an endopeptidase that breaks down proteins into smaller peptides (that is, a protease). It is produced in the stomach and is one of the main digestive enzymes in the digestive systems of humans and many other animals, where it helps digest the proteins in food.

8). Answer: B

Liver is the largest gland in human body. It is also the largest (internal)organ in our body and can weigh up to 1.5 kg for a human adult. That is, about 1/50th of the body weight is because of liver.

9). Answer: A

Coronary thrombosis is the formation of a blood clot inside a blood vessel of the heart. This blood clot restricts blood flow within the heart.

10). Answer: C

About 80% of kidney stones are partially or entirely of the calcium oxalate type. They form when urine is persistently saturated with calcium and oxalate. Some of the oxalate in urine is produced by the body.
