1. "Bar" is unit of :

Water pressure

Atmospheric pressure

Buoyant force

None of above

The unit "bar" is commonly used to measure atmospheric pressure. Atmospheric pressure refers to the force exerted by the weight of the Earth's atmosphere on a given area. It is commonly measured in units such as millibars (mb) or kilopascals (kPa). Thus, "bar" is a unit of atmospheric pressure.

2. The end of a long bone is connected to another bone by

Ligament

Tendon

Cartilage

Muscle

Ligaments are strong, fibrous connective tissues that connect bone to bone. They provide stability and support to joints by preventing excessive movement and maintaining proper alignment between bones. In the context of the question, ligaments are responsible for connecting the end of a long bone to another bone. Tendons, on the other hand, connect muscle to bone, cartilage is a flexible connective tissue found between bones, and muscles are responsible for movement rather than connecting bones. Therefore, the correct answer is ligament.

4. The decolourising action of bone charcoal is due to its capacity to -

Adsorb

Float

Oxidise

Reduce

Bone charcoal has the ability to adsorb or attract and hold onto impurities and color-causing substances. This is why it is used in various industries, such as water and air purification, to remove impurities and contaminants. The porous structure of bone charcoal provides a large surface area for adsorption, allowing it to effectively remove color and other unwanted substances from liquids or gases. Therefore, the decolourising action of bone charcoal is a result of its adsorption capacity.

5. In which type of rocks are metals like gold and copper mostly found ?

Old Sedimentary

Old Igneous

Old metamorphic

New Metamorphic

Metals like gold and copper are mostly found in old igneous rocks. Igneous rocks are formed from the cooling and solidification of molten magma or lava. When these rocks cool and solidify, they can trap and concentrate minerals, including metals like gold and copper. Over time, through geological processes such as erosion and uplift, these rocks can be exposed at the Earth's surface, allowing for the extraction of these valuable metals. Therefore, old igneous rocks are the most likely type of rock to contain deposits of gold and copper.

6. Directions : Six Persons P, Q, R, S, T and U are sitting in a circle facing one another front to front. P is sitting in front of Q, Q is sitting to the right of T and left of R, P is to the left U and right of S. Who is sitting between P and R ?

S

T

U

Q

S is sitting between P and R because according to the given information, P is sitting in front of Q and Q is sitting to the right of T and left of R. Therefore, S must be sitting between P and R.

Explanation

S is sitting between P and R because according to the given information, P is sitting in front of Q and Q is sitting to the right of T and left of R. Therefore, S must be sitting between P and R.
