Answer:
10581.59 V
Explanation:
We are given that
Magnetic field=B=0.65 T
Speed of electron=
Charge on electron,
Mass of electron,
We have to find the potential difference in volts required in the first part of the experiment to accelerate electrons.
Where V=Potential difference
Mass of electron
v=Velocity of electron
Using the formula
Hence, the potential difference=10581.59 V
Answer:Place the graduated cylinder on a flat surface and view the height of the liquid in the cylinder with your eyes directly level with the liquid. The liquid will tend to curve downward. This curve is called the meniscus. Always read the measurement at the bottom of the meniscus.
Explanation:
The altitude of the pole vaulter as she crosses the bar is 5 m.
<h3>The altitude of the bar</h3>
v² = u² - 2gh
where;
- v is final velocity of the pole vaulter
- u is the initial velocity of the pole vaulter
- h is altitude of the bar
h = (u² - v²)/2g
h = (10² - 1.5²)/(2 x 9.8)
h = 5 m
Thus, the altitude of the pole vaulter as she crosses the bar is 5 m.

Electrical phenomena are commonplace and unusual events that can be observed and that illuminate the principles of the physics of electricity and are explained by them. Electrical phenomena are a somewhat arbitrary division of electromagnetic phenomena
Los fenómenos eléctricos son eventos comunes e inusuales que se pueden observar y que iluminan los principios de la física de la electricidad y son explicados por ellos. Los fenómenos eléctricos son una división algo arbitraria de los fenómenos electromagnéticos.
