If a point has 40 J of energy and the electric potential is 8 V, the charge must be: A. 5 C
<u>Given the following the details;</u>
- Electric potential = 8 Volts
To find the quantity of charge;
Mathematically, the quantity of charge with respect to electric potential is given by the formula;
Substituting the values into the formula, we have;
<em>Quantity of charge = 5 Coulombs</em>
Therefore, the quantity of charge must be <em>5 Coulombs.</em>

Answer:
Cannonball b spends more time in the air than cannonball a.
Explanation:
Starting with the definition of acceleration, we have that:
Since both cannonballs will stop in their maximum height, their final velocity is zero. And since the acceleration in the y-axis is g, we have:
Now, this time interval is from the moment the cannonballs are launched to the moment of their maximum height, exactly the half of their time in the air. So their flying time t_f is (the minus sign is ignored since we are interested in the magnitudes only):
Then, we can see that the time the cannonballs spend in the air is proportional to the vertical component of the initial velocity. And we know that:
Finally, since 
and 
, we can conclude that:
In words, the cannonball b spends more time in the air than cannonball a.

Answer:
The Bohr model shows that the electrons in atoms are in orbits of differing energy around the nucleus
Explanation:
(think of planets orbiting around the sun). Bohr used the term energy levels (or shells) to describe these orbits of differing energy.
so to increase Ue by 16 times you gotta reduce R(distence) by 16 times
