Answer:
0.19 kg
8 N
1.964 N
58.86 N
15 kg
Explanation:
w = Weight of an object = 100 N
g = Acceleration due to gravity of Earth = 
m = Mass of an object
Weight is given by

Mass of the object is 0.19 kg
g = 
m = 4 kg

Weight of the object is 8 N.
m = 200 g

Weight of the object is 1.964 N.
Weight is the force the Earth exerts on an object which is on the surface of the Earth.
m = 6kg

The force of the object is 58.86 N.
w = 150 N
a = g = 

Mass of the object is 15 kg.
Answer:
a) increases
b) decreases
c) does not change
d) increases
Explanation:
The vapour pressure of a liquid is dependent on;
I) the magnitude of intermolecular forces
II) the temperature of the liquid
Hence, when any of these increases, the vapour pressure increases likewise.
Similarly, the boiling point of a liquid depends on the magnitude of intermolecular forces present because as intermolecular forces increases, more energy is required to break intermolecular bonds.
Lastly, increase in surface area of a liquid does not really affect it's vapour pressure.
