<span>A. Teens who are heavy users of alcohol and drugs typically have low levels of self-control and are easily frustrated.
B. Teens under the influence of drugs and alcohol are more likely to act impulsively.

Answer:
Buoyant force which is equal in magnitude to the fish's weight
Explanation:
A fish floating motionless below the surface of a lake, is an equilibrium position with the water.
Hence, upward force must be equal to downward force.
The downward force is due to fish's weight while the buoyant force is the upward force due to force of the water.
Answer
given,
SAT is 500 with a standard deviation of 100.
a sample of 400 students whose family income was between $70,000 and $80,000 had an average verbal SAT score of 511.
sample mean =
=
= 5
95% confidence level is achieved within +/- 1.960 standard deviations.
1.960 standard deviations x 5 is equal to +/- 9.8
confidence interval = 511 - 9.8 --- 511 + 9.8
= 501.2-----520.8
15km = 15,000m
1/2h = 1800s
15,000 / 1,800 = 25/3ms^-1
Since the initial velocity is 30 and the final is 0. 15 is the vave so you can use that with 1/2mv^2 to find the force
