Answer:
B
Explanation:
Because a ball falling down is a good strong force
Answer:
you need to be more specific

Explanation:
Answer:
Lower
Explanation:
Surface tension occurs because molecules at the surface do not have molecules above them, so they cohere more strongly to their neighbours.
The stronger cohesive forces make it more difficult to move an object through the surface than when it is beneath the surface.
The attractive forces in water are strong because of hydrogen bonding.
A hexane molecule is nonpolar, so the only attractions are the weak London dispersion forces.
The cohesive forces at the surface are much lower than those in water, so the surface tension of hexane is lower than that of water at the sane temperature.
<h3>What is pH?</h3>
This is defined as the degree of acidity or alkalinity of a substance and pH from 1.0 - 6.9 is acidic, 7 is neutral while 7.1 - 14.0 is basic.
The aqueous solutions and their appropriate pH can be seen above which is the right choice.

Answer:
The unit of A must be 'atm', and the units of B and C must be 'atmxK'.
If a system is at steady state it means the properties do not vary over time.
Explanation:
The units of pressure must be atm, bar, Pa or mmHg. If we use the atm unit the result of the equation should be the pressure in 'atm'. Thus, the unit of A must be 'atm', and the units of B and C must be 'atmxK'. So, If we replace the equation with the temperatures (T) in Kelvin (K) the result will be in 'atm'.
Problem 2: If a system is at steady state it means the properties do not vary over time. This is the definition of a steady state. Also, every particular steady state will define their own properties but each steady state will no vary their properties over time.
