How does the current values in and out of the battery compare to the sum of currents going through the light bulbs?Note: This is for Parallel circuits.
​

Answers

Answer 1
Answer: The current values in and out of the battery is going to be equal to the sum of the currents going through the light bulbs. In a parallel circuit, the current is divided as it enters different branches and light bulbs. However, the amount of current leaving the battery is always going to be the same as the amount of current entering the battery. Therefore, while current divides in a parallel circuit, the total amount of current always remains the same.

The shifting of the observed wavelength of light due to the motion of the source toward or away from the observer is called the _____________.

Answers

Answer:

doppler effect

Explanation:

When the relative motion of two bodies results in the wavelength becoming shorter this means that the bodies are getting closer. This is known as blue shift.

When the relative motion of two bodies results in the wavelength becoming longer this means that the bodies are getting farther. This is known as red shift.

Collectively this phenomenon is known as the Doppler effect.

Which is heavier, the earth or the moon

Answers


When you say "heavy", you're talking about the gravitational force
between that object and another object, so it depends on what the
"other object" is.

If the "other object" is, let's say, the sun, then the gravitational attraction
between the Earth and sun is about 80 times as much as the gravitational
attraction between the Moon and sun, because the Earth has about 80 times
the mass of the Moon.

But if, somehow, the weight you have in mind is the gravitational attraction
between the Earth and the Moon, then those forces are equal.  The force
of gravity between two objects depends on the product of both masses,
and it's equal in both directions.

If that isn't clear to you, let me give you this additional fact that's guaranteed
to knock you even further off-balance:

Your weight on the Earth is determined by the product of

                           (your mass) times (the Earth's mass).

The Earth's weight on you is determined by the product of

                           (your mass) times (the Earth's mass).

Your weight on Earth is the same as the Earth's weight on you.

An upward force is applied to a 6.0–kilogram box. this force displaces the box upward by 10.00 meters. what is the work done by the force on the box?

Answers

Answer:

The work done by the force on the box is W = 588 J

Explanation:

The work done by the force on the box can be expressed as:

W=mg(h_(2)-h_(1))

where m is the mass of the box, g is the gravitational force g=g=9.8(m)/(s^(2)) and h_(2), h_(1) are the heights of the box in at final and initial moment.

Replacing the values, you have:

W=6.0kg*9.8(m)/(s^(2))*(10.00m-0.00m)

W=588(kgm^(2))/(s^(2))

that is W = 588 J
work = fs = mgh [Ep] = 6(10)(10) = 100

Within an internal combustion engine, the can-shaped component that moves up and down the cylinder and is the main moving part in the engine is theA. connecting rod.
B. piston.
C. spark plug.
D. crankshaft.

Answers

Piston is the part in the combustion engine which moves up and down. Piston is connected in connecting rod which helps to move it.
Spark plugs are used to produce spark.

So the answer is B. Piston

Hope I Helped You!!! :-)

Have A Great Day!!!
Piston is the part in the combustion engine which moves up and down.
