In what way do the state's Aid the national government​
jenyasd209 [6]

Answer:

The states help the national government with their distribution of funds, evaluation of power, and in making congressional decisions.

Explanation:

With the census, a state helps the government figure out how much money a state needs to support its population based on the demographics within its state boundaries. Also, if states do not like how the government is being operated, states have the power to input how the government could improve by the use of bills (earliest form of laws) and protests. States have representation in Congress otherwise known as "delegates" who help decide on Supreme Court cases and pass/deny a law that may be unconstitutional so government cannot abuse their power.

1.) An object exerts a force of 10 lb on an area of 2 square inches. What is the pressure the
PolarNik [594]

Answer:

The pressure this object exerts on the surface is 5lb/in² or 5psi.

Explanation:

Pressure is force per unit area.

Mathematically, pressure is given by the formula;

Pressure = \frac{Force}{Area}

P = \frac{F}{A}

Given the following data;

Force = 10lb

Area = 2in²

Substituting into the equation, we have;

Pressure = \frac{10}{2}

Pressure = 5lb/in² or 5psi

<em>Hence, the pressure this object exerts on the surface is 5lb/in² or 5psi. </em>
