KCSE 2000 MATHEMATICS P1 ANSWERS
2.Acceleration of gravity on Jupiter is higher than that of earth, so a bag of saw dust must be less massive if the greater acceleration on earth is to produce the same pull as sugar bag on earth.
3.Beaker becomes more stable because the position of C.O.G is lowered on melting or water is denser than ice.
4.On earthing negative charges flow to the leaves from earth to neutralize positive charges when the rod is withdrawn the leaves are left with net negative charge.
5.Since the system is in equilibrium let A be the area of piston and P the pressure of steam
P x A x 15 = W (15 + 45)
2.0 x 105 x 4 x 104 x 15 = W x 60
W = 20N
6.Particles of gases are relatively far apart while those of liquids and liquids are closely parked
7.Since the strip is bimetallic when temperature rises the outer metal expands more than the inner metal; causing the strip to try and fold more; this causes the pointer to move as shows
8.This is because metal is a good conductor, so that heat is conducted from outer parts to the point touched; while wood is a poor conductor
9.
10. Can withstand rough treatment
Do not deteriorate when not in use
11. Struts are DE, DC, AD, BD Ties are BC; AB
12.The keepers become magnetized thus neutralizing the pole, this reduces repulsion at the poles, thus helping in retention of magnetism
Force F2 at the ends perpendicular and turning to opposite to F1
15. VR = 4;
16. Efficiency of the system
Efficiency = M.A x 100 = 100 x 1 x 100 = 89.3%
V.R 20 4
= 89%
17. Sound waves
18. Let A’s represent current through the Anometers using Kirchoffs Law
A1 + A2 = A3
But A1 = A2
So A1 = A2 = ½ A3
Similarly A4 + A5 = A3
So that A4 = A5 = ½ A3
So A1 = A2 = A4=A5
19. P = V2; 40 = 2402 R = 1440W
