Distance traveled by the ball is given by

here we know that
speed = 20 m/s
times = 0.25 s
now we have


so ball will travel 5 m distance in the given interval of time
Each of the three choices is tasteless, exhibitionist, juvenile, and dangerous. John should do none of them.
Encountering a news crew, there's no reason for John to call attention to himself in a childish way, or interfere with their work in <em>any</em> way.
What he <u><em>should</em></u> do is:
==> Slow down
==> Pass the scene cautiously
==> Resume his normal, legal speed quietly, in case the crew happens to be recording audio at the moment.
Mysteriously, this course of action is nowhere to be found among the choices listed.
It could be, depending on WHAT distance was graphed,
and how the student labeled the graph's axes.
Most likely, however, she probably drew the graph ...
-- with time on the x-axis increasing to the right,
-- with distance on the y-axis increasing upward,
-- to show the distance FROM the starting point
NOT the distance remaining to the destination.
If that's how she set it up, or if any two of these items are
the other way around, then the line could not slope downward.
THAT would say that the distance from the starting point is
decreasing as time goes on, or the distance remaining to the
destination is increasing as time goes on. That would be silly.
Answer:
Reflection is when light bounces off an object, while refraction is when light bends while passing through an object.
Explanation:
I just learned about this 2 weeks ago actually.
For the law of conservation of energy, the amount of kinetic energy the proton gained in

is equal to the amount of electric potential energy it losts covering the same distance.
The potential difference across which the proton travelled is given by

where E is the electric field intensity. Replacing the numbers, we get

The electric potential energy lost by the proton is given by

where

is the charge of the proton. Therefore, this quantity is equal to

And based on what we said at the beginning, this electric potential energy lost by the proton is exactly equal to the amount of kinetic energy it gained:
