Is Two parallel lines are always coplanar?

Parallel lines remain equal distance apart and never intersect with each other.


If two distinct lines do not intersect are they parallel?

If they are coplanar in a Euclidean space, then yes. If they are not coplanar or not in Euclidean space, then not necessarily.


What condition is necessary for two bodies that are in physical contact to remain in equilibrium?

For two bodies in physical contact to remain in equilibrium, the condition necessary is that the sum of the forces acting on each body must be equal and opposite.


What condition is necessary for two bodies that are in physical contact with each other to remain in equilibrium?

The condition necessary for two bodies in physical contact to remain in equilibrium is that the sum of the forces acting on each body must be equal and opposite.


First condition of equilibrium?

The first condition of equilibrium states that the net force acting on an object must be zero for the object to remain at rest or move at a constant velocity. This condition is also known as the vector sum of all forces being equal to zero.


When allelic frequencies remain unchanged a population is in genetic eqilibrium this statement expresses what?

This statement refers to the Hardy-Weinberg equilibrium principle, which states that in the absence of evolutionary forces, allele frequencies in a population will remain constant from generation to generation. This equilibrium condition can be used as a null hypothesis to assess whether a population is evolving.


What is used to describe the conditions of reaction at equilibrium?

At equilibrium the concentrations of reactants and productas remain constant.


What is used to describe the conditions at reaction at equilibrium?

At equilibrium the concentrations of reactants and productas remain constant.


What term refers to the condition in which the concentration of the reactants and products remains constant over time?

Chemical equilibrium describes a state in which the concentrations of reactants and products in a reversible chemical reaction remain constant over time. At equilibrium, the rate of the forward reaction is equal to the rate of the reverse reaction.


When forces act act parallel to each other but in opposite directions?

When forces act parallel to each other but in opposite directions, they create a state of equilibrium where the net force is zero. This means that the object will not accelerate in any direction, but rather remain at rest or move at a constant velocity.


If a catalyst is added to a system at equilibrium and the temperature and pressure remain constant there will be no affect on the?

Equilibrium position. The catalyst speeds up the rate at which equilibrium is reached by lowering the activation energy for both the forward and reverse reactions equally. The concentrations of reactants and products at equilibrium remain the same.


What we mean by parallel sides?

Parallel sides are lines that remain the same distance apart.
