The velocity of a car traveling in a straight line increases from 0 meters/second to 30 meters/second in 8 seconds. What is the average acceleration of the car?
Answers
Answer :
Explanation :
Initial velocity of the car, u = 0 m/s
Final velocity of the car, v = 30 m/s
Time taken, t = 8 s
Average acceleration of the car is defined as the change in velocity divided by time.
Hence, this is the required solution.

in order to answer this question:
1 full circle ==> 360 degrees .
Got that ?
Now you could set up a proportion:
(30 degrees) / (0.01 second) = (360 degrees) / (time for full period)
Cross-multiply the proportion:
(30°) · (period) = (360°) · (0.01 sec)
Divide each side by (30°) : Period = (360° · 0.01 sec) / (30°)
= (3.6° · sec) / (30°)
= (3.6 / 30) sec
= 0.12 sec .

Another way to look at it:
30° takes 0.01 second
60° takes 0.02 second
90° takes 0.03 second
120° takes 0.04 second
150° takes 0.05 second
180° takes 0.06 second
210° takes 0.07 second
240° takes 0.08 second
270° takes 0.09 second
300° takes 0.10 second
330° takes 0.11 second
360° takes 0.12 second

Not so ! Not only is that statement essentially false,
but it involves significant prevarication as well, too.
Mass is the measure of the quantity of matter in an object.
Volume is a measure of the quantity of space filled by the
object.
The same mass can have many different volumes, usually
depending on its temperature. Just consider one kilogram
of ice, water, and steam . . .

The sentence can be completed as follows:
"Electricity is the movement of charges from one atom to another along a conductor."
The movement of the the charges is due to the presence of a potential difference across the conductor, which pushes the charges. More specifically, in normal conductors, the carriers of electricity are the electrons. Therefore we can rewrite the sentence as
"Electricity is the movement of electrons from one atom to another along a conductor."
Final answer:
Electricity is the flow of electrons from one atom to another along a conductor such as a metal wire. This motion is driven by a potential difference or voltage. While the overall speed of electron movement is slow, the propagation of the electrical effect (current) is near light speed.
Explanation:
Electricity is the movement ofelectrons from one atom to another along a conductor. These carriers of electric charge move due to potential difference, also known as voltage. For example, in a metal wire, free electrons move from the negative (low potential) end towards the positive (high potential) end of the wire, creating a flow of electricity.
An interesting detail is that while the electrons move quite slowly overall, the electric effect they produce, the electric current, propagates almost at the speed of light.
The conductor is a material that allows this movement of electrons to occur efficiently, metals like copper or silver are typical conductors.
