Hi,

Homelessness is a public health issue and it can have many negative impacts on a local community. What aspects of homelessness have the most influence beyond the local community and have impacts for the global community? Think in terms of things like lifestyle, population dynamics, disease, climate change, disaster response, etc.

And With a focus on the entire planet, why does homelessness topic matter?

Kw , the equilibrium constant for the ionization of water by the equation below, is 1.0 x 10 -14 . What does that mean when we are considering pure

Select one:

a. More ions exist than water molecules.

b. The majority of the molecules present are in the form of H2O.

c. The amount of water is the same as the amount of the ions present.

d. There will always be more hydronium ions present than water at equilibrium.

A mass M is located a distance D up aninclined plane (inclined by an angle theta).

/in /by

A mass M is located a distance D up an inclined plane (inclined by an angle theta). The mass is at rest, but it is experiencing the force of gravity and a frictional force opposing the motion of the block down the inclined plane. The normal force is a force perpendicular to the inclined plane equal in magnitude to the component of the block’s weight that is also perpendicular to the inclined plane.  A frictional force is proportional to the normal force. Complete the diagram by drawing a vector diagram showing each force. Provide equations that represent the net forces along the direction of the plane and perpendicular to the plane.

Can you help me I am really stuck. Thank you for your help

Traverse each bridge do not recross any bridge return to the starting point Euler circuit: return to the starting point by traveling each edge of the graph once and only once. The distance between two nodes is defined as the number of edges along the shortest path connecting them. If the two nodes are disconnected, the distance is infinity. Is there a solution to the Konigsberg bridge walking problem?
