The specific gravity is how the density of the object compares to the density of water. Water's density is 1gram per milliliter. We just need to figure out the density of the object.
The object is .8 kg and it displaces 500mL of water, so the density is the mass divided by the volume. Since the density of water is given in grams, we have to convert the objects mass from kg to g and then we can get the density.
.8kg * 1000g/kg = 800 grams
So
800g/500ml = 1.6grams/mL this is the density.
So divide the density of your object by the density of water, which is 1g/mL, you get 1.6 as the specific gravity. This means the object is 1.6 times more dense than water.
the position that has least kinetic energy is option D
Measures angular displacement per unit time.
Answer:
Final volume = 0.42 cubic meters
Explanation:
The question is incomplete. The initial conditions are
Initial temperature ,
= 310 K
Initial volume ,
= 0.5 cubic meter
Number of moles = 2.5
Since, from the ideal gas equation we get,
PV = nRT
P 
= 12886.7 Pa
Final pressure= 15464.04 Pa
Since temperature is constant,
PV = constant
V = 0.42 cubic meters.
Hence final volume = 0.42 cubic meters
