2) What must be connected for an electrical current to flow in a simple current?
<em>d.moving magnets,conductors, load to do work
</em>
here moving magnets will work as generator and conductors is used as connectors.
5)What is the purpose of a load in a circuit?
<em>c.provide resistance to keep the voltage strong
</em>
Load will provide the resistance to the circuit and help to build the voltage across it
6) What cause an electric current from a generator
<em>d.Magnets and conducting wires move near each other
</em>
here when magnets move near wires then it will induce the electric current and behaves like generators
7) What do all generators have in common
<em>b.they transform mechanical into electrical energy
</em>
They have magnets and rotating coils which will convert magnetic energy to electrical energy
8) How can we measure electrical current
<em>b.the pressure force is voltage;the # of electrons moving is amperes
</em>
this voltage and number of electrons will help to calculate current
Answer:
B
Explanation:
Gravity is when objects are pulled down to earth
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.
Answer:
The plants depend on animals and animals depend on plants.
Plants depend on animals for nutrients, pollination and seed dispersal. Animals are totally dependent on plants. First of all plants produce oxygen which is vital for life on earth. Then, for many animals plants are their basic food, or if plants don’t make up 100 % of their diet, plants are nevertheless essential in their food supply.
Answer:
Explanation:
Your numbers seem wonky, so I'll just assume that the initial displacement is a distance A (Amplitude) from the equilibrium position. Spring constant = k
Initial potential energy is
PE = ½kA²
As potential energy and kinetic energy are constantly exchanging in SHM,
the position x where half of the original spring potential exists is found where
½kx² = ½(½kA²)
x² = ½A²
x = (√0.5)A
x ≈ 0.707A
just plug in your actual starting position A
With A = 5.2 cm
x = 3.67695... 3.7 cm
