the temperature rises and the ice expands
the temperature remains constant and the volume of ice decreases
the ice gives out heat as it melts
the mass remains constant and the temperature increases

zinc
brass
copper
gold
silver
Correct answer is B
R.D = \(\frac{\text {density of object}}{\text{density of water}}\)
= \(\frac{\frac{0.425}{50 10^-6}{1000}\)
= 8.5
mg
(m + pv)g
(m - pv)g
pvg
[M/m-pv]g
Correct answer is C
Tension = upthrust on object
= weight in air - weight i liga
= mg - pvg
= (m - pv)g
95\(\Omega\)
110\(\Omega\)
595\(\Omega\)
995\(\Omega\)
1005\(\Omega\)
Correct answer is D
V = IR
50 = 50 x 10-3 (5 + R)
R = 995\(\Omega\)
