Answer:
False
Explanation:
The force of gravity is not only determined by the mass of the two objects but also the distance.
The law of universal gravitation states the product of the masses is directly proportional to the gravitational force, but it is also indirectly proportional to the square of the distance between them.
In other words, the greater the masses of each the greater the gravitational force, but the greater the distance between the two, the weaker the gravitational force.
Answer:
55.3 M
Explanation:
Given temperature = 25°C
Density = 0.997 g/mL
Based on density the mass of water per L = 997 grams
The molar mass of water = 18
The moles of water =
The molarity is defined as the moles of water per litre.
The moles = 55.3
Volume = 1 L
So molarity = 55.3 /1 = 55.3 M
Answer:
Density is a physical property that is determined by dividing the mass of a given amount of a substance by its volume.
Explanation:
Answer:
Newtonian fluids have a constant viscosity that does not change and non newtonain fluids have a viscosity that varies.
Explanation
Newtonian fluids have a constant viscosity and a zero shear rate at zero shear stress. Non-Newtonian fluids have a variable viscosity and a varible relationship with shear stress.
