2. diameter of a wire.
3. mass of a car.
4. length of a table.

(iv)A force which prevents a body to slide is called:

1. stretching force.
2. restoring force.
3. frictional force.
4. compressional force.

(v)The ability of a body to float in a fluid is known as:

1. the law of upthrust.
2. the law of Archimedes
3. the law of floatation.
4. floating.

(vi)One of the following is the condition for a body to float in water:

1. The mass of a floating body is greater than displaced water.
2. The density of the body must be less than the density of the fluid.
3. The upthrust due to the liquid must be smaller than the weight of the body.
4. The displaced water is less than the floating body.

(vii)In a solid state the force of attraction between molecules is greater because particles are:

1. closely packed together.
2. somehow apart.
3. not closely packed together.
4. moved so randomly.

(viii)The phenomenon observed when maize flour is poured on top of water is called:

1. diffusion. 
2.  capillarity.
3. surface tension.
4. osmosis.

(ix)Density and height are factors which affect pressure in:

1. solid.
2. solid and liquid.
3. liquid.
4. gas.

2. translucent.
3. opaque. 
4.  Newton.

(xiii)What term refers to the stationary accumulation of charges on an object?

1. Current electricity
2. Static electricity
3. Charging.
4. Polarization.

(xiv)The flow of electrons in a material is called:

1. uniform speed.
2. acceleration.
3. distance.
4. displacement.

(XViii)Why is the mechanical advantage less than three in a single rope three pulleys system?

1. Because the effort may vary.
2. Because the load rises.
3. Because the upper pulley does not move
4. Due to friction on pulleys.

(xix)The product of mass of a body and its acceleration is a result of:

1. Newtons second law of motion
2. Law of inertia.
3. Newtons third law of motion.
4. Momentum change.
