a) water + organic substances
b) both (water only) and (water + inorganic substances)
c) water only
d) water + inorganic substances

Question. A mixture of sulphur and carbon disulphide is
a) heterogeneous and shows Tyndall effect
b) heterogeneous and does not show Tyndall effect
c) homogeneous and shows Tyndall effect

a) Non-zero force
b) Frictional force
c) Gravitational force
d) Internal force
Answer
(b) Frictional force
Explanation: Any object which face non zero force will have some change in speed if the body is at rest or moving. So it is not possible to travel with constant speed. The forces can do work against each other. For example, you could push the object at constant speed over a rough surface. The net force on the object is
zero.
Question. A jet engine works on the principle of Newton’s:
a) second law of motion
b) first law of motion
c) none of these
d) third law of motion
Answer
(d) third law of motion
Explanation: The jet engine sucks air in at the front with a fan. A compressor raises the pressure of the air. The compressor is made with many blades attached to a shaft. The blades spin at high speed and compress or squeeze the air. The compressed air is then sprayed with fuel and an electric spark lights the mixture. The burning gases expand and blast out through the nozzle, at the back of the engine. As the jets of gas shoot backward, the engine and the aircraft are thrust forward (Newton’s third law of motion).

Question. A moving body is covering a distance directly proportional to the square of time. The acceleration of the body is:
a) constant
b) zero
c) increasing
d) decreasing
Answer
(a) constant
Explanation: Displacement is proportional to square of time s is displacement and t is time then,

Acceleration(a) = 2k = constant.
So, the motion of the body is constant acceleration.
Question. Rocket works on the principle of conservation of
a) mass
b) velocity
c) energy
d) momentum
Answer
(d) momentum
Explanation: Rocket works on the conservation of momentum. In a rocket, the fuel burns and produces gas at high temperature. These gases are ejected out of the rocket from a nozzle at the back side of the rocket. The ejecting gas exerts a forward force on the rocket which help in accelerating. Through the mass of gases escaping per second is very small and their momentum is very large due to their tremendous velocity of escape. An equal and opposite momentum is imparted to the rocket which despite its large mass builds up a high velocity.

Question. Which cell does not have perforated cell wall?
a) Companion cells
b) Vessels
c) Trachieds
d) Sieve tubes
Answer
(a) Companion cells
Explanation: Tracheids and vessels are xylem elements and are concerned with the transport of water. They are long tube-like structures with partially or completely dissolved walls to form water pipes (in vessels) and pits in cell wall (in tracheids) for conducting water. Sieve tubes are slender tube-like structures with their end walls perforated by numerous pores and are called sieve plates. They are phloem elements and are main food conducting elements. Companion cells possess numerous mitochondria and ribosomes and are supporting units of sieve tubes.

The non-striated muscles or smooth muscles are found within the walls of the elementary canal, bladder, and blood vessels.
Question. Assertion (A): If a particle is moving with constant velocity, then the average velocity for any time interval is equal to instantaneous velocity.
Reason (R): If average velocity of a particle moving on a straight line is zero for a given time interval, then instantaneous velocity at some instant within this interval may be zero.
a) Both A and R are true and R is the correct explanation of A.
b) Both A and R are true but R is not the correct explanation of A.
c) A is true but R is false.

Question. A mixture of iron filings and sulphur is heated in a hard boiling tube. Which of the following will be observed?
a) Iron will melt first
b) Sulphur will melt first
c) The mixture becomes red hot without melting
d) Mixture sublimes
Answer
(b) Sulphur will melt first
Explanation: When we start heating a mixture of iron filing and sulphur, the sulphur melts reacting exothermically (that is with the production of heat) with the iron filings to form the compound Iron (II) sulfide. The compound formed has properties that are different from both sulfur and iron. For instance, the compound does not have the magnetic properties of iron, and thus a magnet that could have easily separated iron nails and sulphur initially, will not be able to separate iron and sulphur from Iron (II) sulphide.
Question. A student took 5 g of powdered arhar dal in a test tube and added 5 ml water into it. She shook the test tube vigorously. After adding a few drops of HCl she observed that the dal tested positive for adulteration with metanil yellow. The observation she noted was:

A solution that has dissolved as much solute as it is capable of dissolving, is said to be a saturated
solution. In other words, when no more solute can be dissolved in a solution at a given temperature, it
is called a saturated solution. If the amount of solute contained in a solution is less than the saturation
level, it is called an unsaturated solution. Chromatography is the technique used for the separation of
those solutes that dissolve in the same solvent. The principle is that immiscible liquids separate out in
layers depending on their densities. Sublimation is also used to separate substance.

Plant cells, in addition to the plasma membrane, have another rigid outer covering called the cell wall. The cell wall lies outside the plasma membrane. The plant cell wall is mainly composed of cellulose. The nucleus has a double-layered covering called a nuclear membrane. The nuclear membrane has pores that allow the transfer of material from inside the nucleus to its outside, that is, to the cytoplasm. The nucleus contains chromosomes, which are visible as rod-shaped structures only when the cell is about to divide. Chromosomes contain information for the inheritance of characters from parents to the next generation in the form of DNA. The nucleus plays a central role in cellular reproduction, the process by which a single cell divides and forms two new cells.
