• Diagram 1 shows a man is in a leaking sampan. He noticed that the spurt coming from the hole at the bottom of the sampan is higher compared to the one from the side.

Inference :The pressure in the water depends on the depth of the waterHypothesis:As the depth of water increases , the pressure in the water inceases.

• The inertia depends on the mass• As the mass increases as the inertia increases

• The final velocity of the girls depends on the initial height

• As the initial height increases ,the final velocity increases

• The kinetic energy depends on the elastic potential energy

• (b)As the elastic potential energy increases ,the kinetic energy increases

• The pressure between two solids depends on the surface area

• As the surface area increases the pressure decreases

Arrangement:

The pressure in the water depends on the depth of the water

(b) As the depth of water increases , the pressure in the water inceases.

The buoyant force depends on the weight of water displaced// the buoyant force depends on the depth of object immersed in the water.(b) As the weight of water displaced increases the buoyant force increases

• The heat depends on the mass• (b) As the mass increases , the heat increases

• Pressure depends on volume// Volume influences pressure

• (b) When the volume decrease , the pressure increase

• The volume of the gas depends on the temperature

• (b) The larger the temperature, the larger is the volume of a fixed mass of gas. / The volume of a gas varies directly with its temperature.

The angle of reflection depends on the angle of incidence(b) The angle of reflection increases as the angle of

incidence increases.

The apparent depth depends on the real depth(b) The apparent depth increases as the real depth increases

The linear magnification depends on the object distance(b) The greater the object distance, the smaller the linear magnification

• mass/volume/ influences change of temperature of water• (b) As mass /volume decreases temperature change

increases

• The brightness of the bulb depends on the temperature.

• The higher the temperature, the higher the resistance.

• The density of liquid affects the apparent depth // The apparent depth depends on density of liquid

• The apparent depth increases as the density real depth decreases.

• The magnitude of an induced current depends on the speed of the relative motion between conductor and magnet

• (b) The magnitude of an induced current increases as the speed of the relative motion between conductor and magnet increases.
