x-rays
sound waves
water waves
tidal waves
Correct answer is A
No explanation has been provided for this answer.
100oC
227oC
273oC
500oC
Correct answer is B
\(\frac{P_1}{T_1} = \frac{P_2}{T_2} = \frac{3}{300} = \frac{5}{T_2}\)
T\(_2\) = 500°C
°C = 500 - 273 = 227°
temperature
energy
viscosity
pressure

4800J
1200J
480J
202J
Correct answer is C
Q = mc\(\theta\)
= 200 x 0.4 x 6 = 480J
0.00030k-1
0.00032k-1
0.01970k-1
0.02030k-1
Correct answer is A
Ya = \(\frac{\text{Vol. expelled}}{\text{Vol. left x temp. change}} = \frac{0.75}{49.25 \times 50}\)
= 0.00030k-1
