8 0

Answer:

Explanation:

You can calculate the total electric charge that passes through the conductor as q=It=(180\times 10^{-3})(5\times 60)= 54 C. It means that the number of electron that passes through the conductor is:

n=\frac{q}{e}=\frac{54}{1.6\times 10^{-19}}=33.75\times 10^{19}

what was the temperature change in Celsius degree if it is changed from 44 degree fahrenheit to -56 degree fahrenheit​
wel

Answer:

-11.11 degree Celsius

Explanation:

The change was 44 degree fanhereit

To 56 degree fanhereit

Therefore the temperature range can be calculated as follows

56-44

= 12 degree fanhereit to Celsius

= 12-32×5/9

= -20×5/9

= 100/9

= -11.11 degree Celsius

What is the definition of visible white light wave (RoyGBive)
uranmaximum [27]

There's no such thing as a wave of white light.  Every light wave with
a certain wavelength has some color.  White light is a mixture of all
the different wavelengths with all of the different visible colors. 
They're ALL there in white light.  When they all enter your eye at
the same time, your brain gets the message of brightness with
no particular color, which we call "white light".

Two objects with the same mass move with the same speed but in opposite directions. Compare their kinetic energies.
ddd [48]

Answer:

A.  Kinetic energies are equal.

Explanation:

The kinetic energy of the bodies will be equal since the mass and speed are the same.

Kinetic energy is the energy due to the motion of a body.

Mathematically;

           K.E  = \frac{1}{2} m v²

m is the mass

v is the speed

 The kinetic energy is a scalar quantity with no regard for direction.

Modern nuclear bomb tests have created an extra high level of14C in our atmosphere. When future archaeologistsdate samples from
Ipatiy [6.2K]

Answer:

Too old(Ex. if real time is 1000 then they estimate >1000)

Explanation:

This is because with time our planet may have a definite function which describes temperature.(Because of all the factors and global warming except nuclear bomb testing)

Now nuclear test on planet have significant effect on temperature rise.

Also 14°C rise in temperature is good one because of this.

If future archaeologists only consider that  uniform function as above mentioned then they estimate more time then the real one.

Thus too old is right answer.
