Answer:

These intentions notwithstanding, most critics found many of the topics and conclusions in the book unpalatable. The Bell Curve was instantly controversial. One of the greatly debated theories put forth by the authors in this book involved how intelligence quotient (IQ) was related to poverty, educational achievement, and parenting. Herrnstein and Murray described American society as a pyramid. A high-IQ minority sat at the top, above a much larger, low-IQ base. Variation in IQ can be represented using a bell curve. Roughly 68 percent of all people score within 15 points of the mean (a perfectly average IQ of 100). Another 15 percent scored within 15 points of that standard deviation, with the remainder lower or higher.

Answer:

These intentions notwithstanding, most critics found many of the topics and conclusions in the book unpalatable. The Bell Curve was instantly controversial. One of the greatly debated theories put forth by the authors in this book involved how intelligence quotient (IQ) was related to poverty, educational achievement, and parenting. Herrnstein and Murray described American society as a pyramid. A high-IQ minority sat at the top, above a much larger, low-IQ base. Variation in IQ can be represented using a bell curve. Roughly 68 percent of all people score within 15 points of the mean (a perfectly average IQ of 100). Another 15 percent scored within 15 points of that standard deviation, with the remainder lower or higher.

According to The Bell Curve, nature superseded nurture as a contributor to intelligence. A high IQ was associated with lower risks of crime, incarceration, divorce, poverty, unemployment, and school dropout rate. It presented data to support claims that those with low IQ scores are more likely to drop out before completing high school. They are also less likely to earn a college degree and more likely to have children whom they cannot financially support on their own. More specifically, Herrnstein and Murray saw increased instances of low birth weight, poor motor skills, and poor social development among children with low-IQ parents.

A Turtle and a Snail are 360 meters apart, and they start to move towards each other at 3 p.m. If the Turtle is 11 times as fast
Neko [114]

Answer:

Snail's speed = \frac{30m}{2400s} = 0.0125m/s

Turtle's speed =  \frac{330m}{2400s} = 0.1375m/s

Explanation:

Let the snail's speed be x m/s

The turtle's speed then is 11x m/s

Speed = Distance ÷ Time

Since speed and distance are directly proportional;

The ratio of the distances snail and turtle cover before they meet is x:11x respectively.

Simplified, the ratio of snail distance : turtle distance = 1:11

So snail covers a distance of \frac{1}{12} × 360 = 30m

And turtle covers a distance of \frac{11}{12} × 360 = 330m

The time each took before they met is 40 × 60 = 2400 seconds

Snail's speed = \frac{30m}{2400s} = 0.0125m/s

Turtle's speed =  \frac{330m}{2400s} = 0.1375m/s

What is the efficiency of a machine if your work on the machine is 1200 j and the machines output work is 300 j?
inysia [295]

Answer:

The efificiency is 0,25 of the machine  (25%). See the explanation below

Explanation:

We calculate the efficiency with this formula:

Efficiency = energy obtained/energy supplied= 300 Joule/1200 Joule

Efficiency= 0,25

Efficiency(%) = 0,25 x100 = 25%

A physics department has a Foucault pendulum, a long-period pendulum suspended from the ceiling. The pendulum has an electric ci
antoniya [11.8K]

Answer:

t=37 mins -> 2220sec

We want "T" which is the pendulum time constant

Using this equation

.5A=Ae^(-t/T)

The .5A is half the amplitude

Take ln of both sides to get ride of Ae

=ln(.5)=-2220/T

Now rearrange to = T

T=-2220/ln(.5) = 3202.78sec / 60 secs = 53.38 mins -> first part of the answer.

The second part is really easy. It took 37 mins to decay half way. meaning to decay another half of 50% which equals 25% it will take an additional 37 mins!
