Answer:

2. high or low

Explanation:

A circuit with high-diameter connecting wires at a low temperature will have the least electrical resistance.

According to Ohm's law, the current flowing through a current carrying conductor is directly proportional to the potential difference across its terminal and inversely proportional to resistance at a constant temperature.

Mathematically, V = IR.

Where;

V = Voltage

I = Current

R = Resistance

Some of the factors affecting resistance of a wire are;

- The resistance of a conducting wire is inversely proportional to its cross-sectional area (diameter).

- The resistance of a conducting wire is directly proportional to its temperature.

Andreas93 [3]

Answer:

The creation of "designer drugs" is outpacing the ability of society to enact laws to prohibit them. Many of these substances have negative side effects, ranging from violent behavior to death.

40. Which of the following responses to the problem would best fit the "crime control" philosophy?

a. Government takes steps to limit the availability of ingredients used in the manufacture of designer drugs.

b. Design a public awareness campaign to warn potential users of the dangers presented by use of these drugs.

c. Partner with community leaders to identify underlying social issues promoting the drug subculture.

d. Pass legislation and increase enforcement efforts to send a message of "zero tolerance" to those who manufacture, sell, and use designer drugs

The answer to the above question is

d. Pass legislation and increase enforcement efforts to send a message of "zero tolerance" to those who manufacture, sell, and use designer drugs

Explanation:

State governments, naturally provide early response to the domestic issue of designer drug abuse than the federal government through the early banning of synthetic drug use.

State legislation on restricting designer drug use can be defined into three groups including

1. Specific synthetic substance ban

2. Ban on generic language

3. Ban based on the effect a substance has on the body.

It can be clearly demonstrated that legislation which combines this three categories is highly effective in reducing the supply and use of designer drugs.

A cantilever beam AB of length L has fixed support at A and spring support at B.

atroni [7]

The force in the spring will be $F =\dfrac{KPl^3}{3EI}$ .

The deflection of the beam will be $\rho$ = $0.15(\dfrac{KPL^3}{3EI})$

<h3>What is a cantilever beam?</h3>

A rigid, horizontally extending structural member known as a cantilever is supported at only one end. Typically, it extends from a solidly affixed flat vertical surface, such as a wall.

Given that:-

A cantilever beam AB of length L has fixed support at A and spring support at B.
The spring behaves in a linearly elastic manner with stiffness k. If a concentrated load P is applied at B.

The spring force will be calculated as:-

$F = kx$

Deflection will be given by:-

$x = \dfrac{PL^3}{3EI}$

The spring force will be calculated by:-

$F = \dfrac{KPL^3}{3EI}$

The deflection of the beam will be given as:-

$\rho = \dfrac{0.15KPL^3}{3EI}$

Therefore the force in the spring will be $F =\dfrac{KPl^3}{3EI}$ ..The deflection of the beam will be $\rho$ = $0.15(\dfrac{KPL^3}{3EI})$
