Different microscopic organisms cause different diseases. when a dangerous microscopic organism is transferred from one person to many people, the disease it carries will spread.

why is this considered a theory instead of a hypothesis or a law?

it is a statement of fact about how nature works instead of an explanation.
it provides an explanation for many observations and accepted hypotheses.
it describes how to test a possible explanation of one specific relationship.
it has not changed over time even though new technology has been developed.

Hi!

The correct answer would be:

It provides an explanation for many observations and accepted hypotheses.

Explanation

A law is a statement of fact that differs from a theory or hypothesis in that it does not provide an explanation for a phenomenon. It does not change over time, and there are no exceptional cases in it. For instance, a day is 24 hours long. It is an obvious, observable fact. There are no explanations, or exceptions - no days where the day is less or more than 24 hours long.

Now, a theory is an explanation of a hypothesis or an observation or phenomenon. A hypothesis is known to be the reason behind a certain observation, and if the hypothesis survives scrutiny and tests, it is established as a theory - but it may be replaced by better theories or grow obsolete over time, such as the atomic theory which stated that atoms were the smallest indivisible particle in nature.

Hope this helps!

Answer from: Quest

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm. the wire diameter is d = 0.9 mm. the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2) in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.

explanation:

Answer from: Quest

Kinetic energy = 1/2mv^2. since the mass is constant we can form a ratio of it's kinetic energy at 60 divided by that at 30 to see ke(60)/ke(30) = +(60^2)/30^2). this may be said to 300% increase.
