We know, density = Mass / volume
Here, mass = 34.8 g
v = 22.8 ml = 22.8 cm³
Substitute their values,
d = 34.8/22.8
d = 1.52 g/cm³

Answer: C
Gauge pressure = 156 kPa ,
What is absolute pressure =?
We know that,
absolute pressure = gauge pressure + atmospheric pressure
Pabs = Pgauge + Patm
= 156 + 101.3 <em> </em><em> (since atm.pr. = 101.3 Kpa)</em>
<em> </em><em>= 257.3 KPa absoulte</em>
<em> approximately = 256 KPa absolue</em>
Answer:
F= 10.4 x10^6 N
Explanation:
A/C to Coulomb's law
F = k q1 q2 / r^ 2
F = 9x 10^9 x 2 x 3 / 72^2
F= 10.4 x 10 ^6 N
