PolarNik [594]

Answer:

No.

Explanation:

Hot spots don't appear at the barriers of tectonic plates, instead, they originate at hot centres known as mantle plumes. Mantle plumes exist below the tectonic plates and may develop a string of volcanoes on the Earths surface.

In general, court in the United States have repeatedly struck down efforts to include creationism or intelligent design in publi
OverLord2011 [107]
Because they are not supported by the results of any legitimate investigation
that's conducted in accordance with the Scientific Method. 

You may say: 
"Well then, teach both lines of reasoning,
and let each student decide for himself." 

This is suggested by the same people who aren't ready to let their
fourth-grader choose his own clothing, dinner menu, or school.
And it sounds reasonable to a vast mass of citizens who have decided
for them selves that the jury is still out on climate change.

What I'm saying is this:

-- The Scientific Method is a METHOD of investigation that's designed
and developed to remove the effects of human prejudice from the
collection and evaluation of evidence, and to be able to tell bogus
conclusions apart from true ones.  It's the most reliable way we have
of asking and answering questions about the natural world.

-- Some questions CAN'T be studied with the Scientific Method,
because experiments generally can't be constructed.  These include
matters of religion and faith.  Nobody can flatly state that those are
right or wrong.  We have no reliable way to say, either way. 
The only way to decide is . . . faith.   

-- It is illegitimate to take the answer to a question of faith that can't be
derived scientifically, and a scientifically derived conclusion, set them
down next to each other on the same table, and pretend that they can be
compared.

-- When you put them next to each other, say that they're equivalent,
and tell people "go ahead and choose one or the other", the situation
is bogus, the comparison is dishonest, and people who are untrained
or uneducated or immature are not qualified to "choose".

That's why.

This is my opinion.  I could be wrong.

Personally, I happen to be a believer.  But I cannot prove anything I believe
to anyone else ... not with rational argument, and not with evidence.  Those are
elements of the scientific method.  They're not applicable, and they don't work,
in matters of faith.

A highway patrolman traveling at the speed limit is passed by a car going 20 mph faster than the speed limit. After one minute,
Oksi-84 [34.3K]

Answer:

It will take 40 seconds to catch the speeding car

Explanation:

Initial speed of the patrolman = 55 mph

after one minute speed of patrol man = 115 mph

now acceleration of patrolman is given by

a = \frac{v_f - v_i}{t}

a = \frac{115 - 55}{1/60} = 3600 m/h^2

now at this acceleration the distance covered by patrolman in "t" time is given as

d = v_i t + \frac{1}{2}at^2

d = 55t + 1800t^2

now we know the speed of the speeding car is given as

v' = (55+20) mph

now in the same time distance covered by it

d = 75 t

now since the distance covered is same

75 t = 55t + 1800 t^2

t = \frac{20}{1800} = \frac{1}{90} h

t = 40 seconds

Why do atoms have an overall neutral charge?
Y_Kistochka [10]
Atoms have an overall charge that is neutral because atoms have equal number of positive protons and negative electrons thus they cancel each other out. This always true for atoms that are stable and in equilibrium.
