The D.A.R.E. program (“Drug Abuse Resistance Education”) began in 1983. In this program, police officers taught special 45-minut

e lessons in classrooms about the dangers of drugs. However, the program was shown to have very little effect; there was only a small, short-term reduction in tobacco use, but no reduction in alcohol or marijuana use. Long-term rates of teen substance abuse did not change significantly.
In 1998, behavioral scientists began looking for different ways to teach this program. The new D.A.R.E. curriculum is called “keepin’ it REAL,” and students spend most of their time practicing refusal strategies with friends rather than being lectured on the possible effects of drugs. The “REAL” acronym stands for the four main strategies the students practice: Refuse, Explain, Avoid, and Leave. There is also much more emphasis on teaching students how to make safe and responsible decisions in all areas of life.

This approach has been shown to be much more effective. Studies of thousands of students show that those who have been through the program use drugs and alcohol less than students who have not been through the program. Additionally, those who were already abusing substances before beginning the program were more likely to stop using the substances. The effects on students’ antidrug attitudes also lasted much longer.

Based on the excerpt, which statement is true?

Antidrug campaigns have little effect on how much students use drugs.
Lots of students use tobacco, but very few use alcohol or marijuana.
Antidrug campaigns can help prevent substance abuse, but cannot reduce it.
Practicing refusal strategies can help students stay sober.

A horizontal force of 92.7 N is applied to a 40.5 kg crate on a rough, level surface. If the crate accelerates at 1.13 m/s2, wha
lord [1]

Answer:

The value is F_f =  46.935 \  N

Explanation:

From the question we are told that

    The  magnitude of the horizontal force is F  =  92.7 \  N

     The mass of the crate is  m  =  40.5 \  kg

     The acceleration of the crate is  a =  1.13 \ m/s

Generally the net force acting on the crate is mathematically represented as

       F_{net} =  F -  F_f =  ma

Here F_f is force of kinetic friction (in N) acting on the crate

      So  

            92.7  -  F_f =  40.5 * 1.13

=>         F_f =  46.935 \  N

The 9-inch-long elephant nose fish in the Congo River generates a weak electric field around its body using an organ in its tail
Alik [6]

Answer:

1.34\cdot 10^{-16} C

Explanation:

The strength of the electric field produced by a charge Q is given by

E=k\frac{Q}{r^2}

where

Q is the charge

r is the distance from the charge

k is the Coulomb's constant

In this problem, the electric field that can be detected by the fish is

E=3.00 \mu N/C = 3.00\cdot 10^{-6}N/C

and the fish can detect the electric field at a distance of

r=63.5 cm = 0.635 m

Substituting these numbers into the equation and solving for Q, we find the amount of charge needed:

Q=\frac{Er^2}{k}=\frac{(3.00\cdot 10^{-6} N/C)(0.635 m)^2}{9\cdot 10^9 Nm^2 C^{-2}}=1.34\cdot 10^{-16} C
