A hypothesis is a tentative and testable explanation, based on observation(s). A hypothesis can be supported or refuted through experimentation or more observation. A hypothesis can be disproven, but not proven to be true.

Answer:

A scientific theory is the in-depth explanation of a natural phenomenon occurring in nature. A theory is formed after the scientific method is followed which supports the theory. A good scientific theory is formed after a number of ideas are linked, tested and proved which are not just guesses.

Since a scientific theory is a well-substantiated and deeply explained idea which overcomes the limited explanation of a proposed hypothesis and unity of many ideas, hence, a theory can be also be known as a well-explained hypothesis.

A good example of scientific theory repeated many times is the "theory of relativity" proposed by Albert Einstein in 1915 which was tested and repeated in 1919 at the time of solar eclipse which was later repeated again by many scientists.

If 2 ma of current flow in your mp3 player, how long will it take for 1 c of charge to flow?

If 2 ma of current flow in your mp3 player, 8.3 mins or 500 sec will take for 1 c of charge to flow.

Electric Charge

Charged material experiences a force when it is exposed to an electromagnetic field due to the physical property of electric charge. You can have a positive or negative electric charge (commonly carried by protons and electrons respectively). Unlike charges attract one another while like charges repel one another. Neutral refers to an object that carries no net charge. Classical electrodynamics, the name given to an early understanding of how charged particles interact, is still accurate for issues that do not call for taking into account quantum phenomena.

The coulomb (C), which bears the name of French physicist Charles-Augustin de Coulomb, is the SI-derived unit of electric charge. The charge symbol, lowercase q, is frequently used.

A French submarine and a U.S. submarine move toward each other during maneuvers in motionless water in the North Atlantic. The F
Mandarinka [93]

Answer:

f_{U}= 1019.72hz

Explanation:

From the equation we are told that:

Velocity of French sub V_{U}= 43.00km/h

Velocity of U.S. sub at V_{F}|=64.00 km//h

French Wave Frequency  F_{F}=1000Hz

Velocity of wave  V_{s}=5470 km/h

Generally the equation for Signal's frequency as detected by the U.S. is mathematically given by

Doppler effect

 f_{U} = \frac{ f_F (vs + v_{U})}{(v_s - v_F) }

 f_{U}= \frac{ 1000 x ( 5470+64)}{(5470-43)}

 f_{U}= 1019.72hz

A 3.0-kilogram toy dump truck moving with a speed of 4.0 m/s starts up a ramp. How high does the truck roll before it stops?
baherus [9]

Before it reaches the ramp, the toy's kinetic energy is

                                        (1/2) (mass) (speed²)

                                   =   (1/2) (3 kg) (16 m²/s²)

                                   =          24 Joules .

On the way up the ramp, its kinetic energy will change to
gravitational potential energy, and it'll stop when it's height
gives it  24 joules of potential energy.

         Potential energy  =  (mass) (gravity) (height)

                    24  joules  =  (3 kg) (9.8 m/s²) (height)

Divide each side by  29.4 kg-m/s²  (that's the same as 29.4 newtons):

                    Height  =  24 joules / 29.4 newtons

                                =      0.816 meter higher than the bottom of the ramp.

When you turn off a light switch, you create an open circuit.<br> True<br> False
galina1969 [7]

Answer:

The answer is True.

Explanation:

Open circuit means incomplete flow of current in a circuit.

When switch is off, the electric current cannot flow throught the circuit for a complete circuit.
