So they could find a quicker, safer, route to China to trade for spices and silk.
Answer:
502.51 kg/m^3
Explanation:
Upthrust on object in water is 40 - 20 = 20 N
Upthrust is equal to the buoyancy forces given as
B = pgv
p is density of water 1000 kg/m^3
g = acceleration due to gravity 9.81 m/s^2
v is the volume of liquid displaced.
Therefore
B = 1000 x 9.81 x v
20 = 9810v
v = 2.038x10^-3 m^3
For Upthrust in unknown liquid, we have 40 - 30 = 10 N
Bouyancy force for the liquid will be
B = P x 9.81 x 2.038x10^-3
NB- the same volume of fluid will be displaced i.e 2.038x10^-3 m^3
Equating we have
10 = P x 9.81 x 2.038x10^-3
10 = 0.0199p
p = 10/0.0199 = 502.51 kg/m^3
Answer:
The Shang made many contributions to Chinese civilization, but four in particular define the dynasty: the invention of writing; the development of a stratified government; the advancement of bronze technology; and the use of the chariot and bronze weapons in warfare.
Explanation:
Answer:
because the government declared it as illegal.
Explanation:
And Pressure is inversely proportional to Area, the more the area, the less the pressure and the less the area, the more the pressure. A sharp knife has less area, thus pressure applied will be more , and that's why it's easier to cut Vegetables with a sharp knife than a blunt knife , even if we apply same force.
