Answer:
Protons and electrons are charged particles. Neutrons have no charge.
P = V^2 / R.
So, 3.3^2 / 0.025 = 435.6W.
Note, you can get the power equation from:
P = V*I. Also, I = V/R.
Substituting V/R in for I in the 1st equation, you get P = V^2 / R.
Answer:
The length of the incline is 3.504 meters.
Explanation:
Let suppose that Julietta's ball decelerates uniformly, then we determine the length of the incline is determined by the following equation of motion:
(Eq. 1)
Where:
- Length of the incline, measured in meters.
- Initial speed of the ball, measured in meters per second.
- Aceleration of the ball, measured in meters per square second.
- Time, measured in second.
If we know that 
, 
and 
, then the length of the incline is:
The length of the incline is 3.504 meters.
