(a)
The change in potential energy of the electron is given by:
where
is the magnitude of the electron's charge
is the magnitude of the electric field
d = 520 m is the distance through which the electron has moved
Substituting into the equation, we find
(b) 78 kV
The potential difference the electron has moved through is given by
where
is the magnitude of the electric field
d = 520 m is the distance through which the electron has moved
Substituting into the equation, we find
Answer:
Explanation:
Given
mass of skier
Force
inclination of Force with horizontal
Water force
Resolving Forces
where a=acceleration of skier
This acceleration is in x direction therefore
Answer:
This is because the 11 positive protons and 10 negative electrons end up with an overall charge of +1.
Explanation:
Answer:
<em>The hang time is 2.04 seconds</em>
Explanation:
<u>2-D Motion
</u>
It referred to as a situation where an object is launched in such a way it describes a curve, reaches a top height and then returns to ground level after traveling a certain distance x away from the launch point.
Let be the launching speed forming an angle with the horizontal reference. The hang time (time the object remains in the air) is given by
Since
Then
We'll use the given values
The hang time is 2.04 seconds
