The density of the object is the ratio of its mass and volume. From the given dimensions above, we determine the volume through the equation,
V = L x W x H
Substituting,
V = (3 cm)(2 cm)(1 cm) = 6 cm³
From the idea presented above,
d = m/V
Substituting the known values,
d = (30 g)/ (6 cm³) = 5 g/cm³
ANSWER: 5 g/cm³
Answer:
2033219.05 J
Explanation:
V = Volume
P = Pressure = 2 atm
m = Mass of water = 1 kg
= Heat of vaporization = 
Work done in an isobaric system is given by

Change in internal energy is given by

Heat is given by


The increase in internal energy of the water is 2033219.05 J
Its A The paper clip is repelled away from the nail because an electromagnetic field magnetized to the nail
B = although each ray of light follows the law of reflection,
950kg. It is W=mg. therefore, mass= W/g which is W/10
=9500/10
=950
