QUESTION AND ANSWER

(specimen A-organic manure) USES

1.poultry dr0pping

2.cow dung

3.farm yard manure

4.compost manure

5.ash

(SP B INORGANIC MANURE) are synthesised artificially USES:

1.N.P.K Fertilizer

2.Ammonium sulphate

3.sodium

4.urea

5.calcium ammonium nitrate

6.super phoshate

7.lime

ADVANTAGES ND BENEFIT OF A

1.supplies nutrient to crops

2. increases soil fertility

3.binds soil particles 2gedar

4. Amproves soil structure

5.increases the yield of crops

6.acts as a buffer in the soil.

METHODS OF APPLYING A.

Padcasting,spraying,side dressing,band methods…

EXPERIMENT TO FIND THE PERCENTAGE OF HUMUS CONTENT IN THE SOIL.

Mass of crucible=xg mass of cruable +drysoil=yg mass of drysoil=y-x=A(g),mass of drysoil alterlating=z-x=B (g),mass of humus=A-B% of humus=A-B/A X100….

EXPERIMENT TO FIND THE % OF SOIL WATER.

METHOD= lnitial mass of the soil is recorded and heated in a crucible the mass is recorded after heating n d the mar7 of water is recorded. Mass of crucible=X (g),mass of cruable + fresh soil=Y-X=A(g),mass of crucible+heated soil=Z (g),mass of dried soil=Z-X=B (g),mass of water=(A-B)(g)

2012 WAEC PHYSICS PRACTICAL

Question 1 => retort stand with clamp;spring balance; two beakers,500cm cube

a) containing water and labelled water

b) containing keroseneand labelled liquid L;set of masses 50g,100g,150g,200g,250g;thread about 1m.

Question 2 => retort stand with clamp;flat bottom plastic petri- dish;syringe about(0-10cmcube). Remove the needle. Pull up the plunger. Use flame from a match stick to melt and seal the tip of the syringe to ensure that it is air tight; use appropriate (plastic to plastic) adhesive to fix the bottom of the petri-dish symmetrically to the top of the plunger; set of masses 500g,1000g,2000gand 2500g.

Note: Masses may be improvised with fine dry sand.

Question 3 => potentiometer (0-100cm) ammeter(0-3A) volmeter(0-5V) 2ohms standard resistor labelled R; two dry cells each 1.5v or 2v freshly charged accumulator;plugkey;eight connecting wires.

GOODLUCK!
