3. An iron rod is heated from a temperature 27°C to 77°C. If the initial length of the iron rod is 100 cm and the coefficient length expansion is 0,000012°/C. So the total length of the iron after expanding is...
Jawaban:
Lo.α.∆t - The Temperature Alter: 77-27=50
100×0,000012×50=0.06
Total length=100+0.06=100.06 cm

6. a. In which material does a sound travel faster, a solid or gas?b. Give on piece of evidence that shows that sound can travel through sold materials. - To measure the length of a long metal rod, engineers send a pulse of sound into one end of it.The sound travel to the other end and is reflected back.The engineers detect this echo, and determine the time taken for the sound to travel from one end of the rod to the other.(pertanyaan untuk c) c. When making measurments on a steel rod of length 400m, they find that the echo returns 0.16s after the initial pulse.What is the speed of sound in steel? bantu gaes :)

8. 14. In Figure RT8.9, determine the length of AC. 10 m 3m 8 m
BC/ED = DA/CA
10/8 = 3/CA
CA = 3 x 8/10
CA = 24/10
CA = 2,4 cm
9. The figure shows two circles of radii 14 cm and 35 cm. Find the area of the shaded part of the figure. ( take 22/7)
Jawab:
Penjelasan dengan langkah-langkah:
r1 = 14 cm
r2 = 35 cm
radius shade area = 35+14 = 49
shade are = 1/2Ï€r²
= 1/2 x 22/7 x 49²
= 3773
may it helps you with the question hihi :D
10. The figure shows a quarter circle with radius 7 cm. What is the perimeter of the quarter circle?
r = 7 cm
1/4 p = ( 1/4 x π x 2 x r ) + 2r
(1/2 x 22/7 x 7 cm) + 14 cm
11 cm + 14 cm = 25 cm
11. the length of piece of steel at a temperature of 20°C is 2 m. It is known that the length expansion coefficient is 0.000011/°C. If the steel is heated to atemperature of 80°C, then the length of the rod will become: a) 0,00132 b) 0,00176 c) 2,00132 d) 2,00176 (tolong dengan cara ya thx)

The length of an aluminum stick at a temperature of 300C is 2m and its length expansion coefficient is 0.000026/0C. if it’s heated until 500C, calculate : a. increase in length of aluminum b. final length of aluminum 3. The metal stick has length of 10 m. If its length expansion coefficient is 0.00017/0C and the metal stick is heated from 270C until 970C, calculate the final length of aluminum!
Jawaban:
[tex] \frac{(c - 0)}{(100 - 0)} = \frac{(74 - ( - 10))}{(110 - ( - 10))} \\ c = \frac{84 \times 100}{120} \\ c = {70}^{0} [/tex]
[tex]dl = lo \times \alpha \times dt \\ = 2 \times 0.000026 \times (50 - 30) \\ = 0.000052 \times 20 \\ = 0.000104m \\ [/tex]
Panjang akhir = 2.000104 m

16. An iron rod has the length of 2 m and the temperature of 283 K. If its linear expansion coefficient is 0.000011/K, the iron rod length at 303 K is ... m.
Jawaban:
2,0004 m
Penjelasan:
Known :
Lo = 2 m
ΔT = 303 K - 283 K = 20 K
α = 0,000011/K
Asked
Iron length ar 303 K?
Solution :
Lt = Lo. (1 + α . ΔT)
Lt = 2 . (1 + 0,000011 . 20)
Lt = 2 . (1,00022)
Lt = 2,0004 m
