Explanation:
If a question says "at what point does the ball stop?", it means we need to find the position of the ball when its final velocity is equal to 0. It can be calculated using the equation of kinematics as follows :
d = ut + (1/2) at²
and
v²-u²=2ad
Where, u is initial velocity, v is final velocity, a is acceleration, t is time and d is displacement.
A electron has a negative charge. They represent energy levels.
An example of the use of an electron is the spherical shell. The larger the shell, the more energy the electron has.
Answer:
no it would not. that is an open circuit and it would need to be closed at the switch for current to flow.
Answer: Option 2
Explanation:
Option 1 is wrong because there are 2 protons and 2 neutrons in nucleus.
Option 3 is wrong because there are two electrons moving around nucleus.
Option 4 is wrong because electrons are negatively charged and are moving around the nucleus.
Option 5 is wrong because there equal amount of protons and electrons with 2 each.
