CHAPTER : IMPULS AND IMPULSIVE FORCE

Rajah 1.1 menunjukkan sebiji belon dilepaskan dari ikatannya. Rajah 1.2 menunjukkan seekor so-

tong bergerak ke depan apabila melepaskan sejumlah dakwat hitam yang banyak ke belakang.

Diagram 1.1 shows a bal-

loon be- ing released

from a grip. Diagram

1.2 shows a cuttlefish mov-

ing for- ward by releas-

ing a big volume of black

ink back- wards.

(a) i. Apakah yang dimaksudkan dengan daya?

What is meant by force?

ii. Menggunakan Rajah 1.1 dan 1.2, bandingkan arah pergerakan belon dan sotong. Kaitkan

arah gerakan untuk menyimpulkan satu konsep fizik yang berkaitan.

Using Diagrams 1.1 and 1.2 compare the direction of motion of the balloon and the

cuttlefish. Relate the direction of motion to deduce a relevant physics concept.

CHAPTER : SOUND WAVES

1 a) Diagram 1.1 shows a guitar. The guitar has strings of different thicknesses. A sound is pro-

duced when a string is plucked. A sound wave is a longitudinal wave.

Rajah 1.1 menunjukkan sebuah gitar. Gitar itu mempunyai tali-tali yang berlainan ketebalan.

Bunyi dihasilkan apabila tali itu dipetik. gelombang bunyi ialah gelombang membujur.

(i) What is the meaning of longitudinal waves? (1m)

Apakah maksud gelombang membujur?

__________________________________________________________________________

(ii) State one difference between longitudinal waves and transverse waves in terms of propaga-

tion.(1m)

Nyatakan satu perbezaan antara gelombang membujur dengan gelombang melintang dalam

sebutan perambatan.

(iii) When plucking the guitar strings, what must be done in order to produce loud sounds and

sounds of high pitch? Explain your answer. (3 m)

Apabila memetik tali gitar, apakah yang mesti dilakukan supaya menghasilkan bunyi kuat

dan bunyi yang lansing. Terangkan jawapan anda.

(b) The coil resistance of a miliammater is 5 ohm and the full-scale deflection current is 10mA. Ex-

plain how to convert the miliammeter for use as a voltmeter which measures up to 5V.

Rintangan gegelung bagi satu miliammeter ialah 5 ohm dan arus pemesongan skala penuh ialah 10

mA. Terangkan bagaimana mengubah miliammeter itu untuk digunakan sebagai voltmeter yang

boleh mengukur sehingga 5 V. (4m)(KBAT)
