Answer:
Planetary Model of the Hydrogen Atom
Anne Marie Helmenstine, Ph. D. The Bohr Model has an atom consisting of a small, positively charged nucleus orbited by negatively charged electrons. Here's a closer look at the Bohr Model, which is sometimes called the Rutherford-Bohr Model.
Explanation:
Answer:
The marble will start to decrease in speed
Explanation:
The longer the table is the more the marbles speed would decrease because marbles can only be fast for a certain amount of time
Considering the definition of impulse, the impulse of the force is 11.06 N×s.
<h3>Impulse</h3>
Impulse is a term that quantifies the overall effect of a force acting over time.
In other words, the mechanical impulse of a force relates said force to the duration of its action. It is a vectorial magnitude that has the direction and sense of the force that produces it.
The impulse I is the product between a force and the time during which it is applied:
I= force× time
The unit of the impulse is the N×s (newton per second).
<h3>This case</h3>
In this case, you know:
- Force= 1400 N
- Time= 0.0079 seconds
Replacing in the definition of impulse:
I= 1400 N× 0.0079 s
Solving:
<u><em>I= 11.06 N×s</em></u>
The impulse of the force is 11.06 N×s.

Answer:
Explanation:
We are going to use the accelerated motion formula 
on the vertical component taking the upwards direction as positive.
Since <em>at maximum height the speed will be 
</em>, the formula can be written as 
, which for our values is:
Written to three decimal places.
Answer:
force is a push or a pull
