Answer:
Explanation:
The electron is the particle that rotates around the nucleus of the atom; it has a negative electric charge equal to :
which is known as fundamental charge.
For an object containing N excess electrons, the total charge of the object is
In this problem, the number of excess electrons in the object is:
Therefore, by plugging it the numbers, we can find the value of Q, the total charge of the object:
Answer:
I would say contact forces
Explanation:
This questions is kind of missing some info but I do know that contact forces need to be either pushed or pulled for a force to happen.
Hope this helped
yes, just like human skin. The bigger you grown the more your skin stretches, I a fish is bigger their skin will stretch leading to broad stripes.
Gravitational potential energy = mass (kg) x gravitational field strength (N/kg) x height (m)
Therefore,
3 x 0.45 x 10 = 13.5J <- it's joules because it's energy
The phase of the moon facing the Earth is always the same, which means that the speed of rotation of the moon and the Earth are the same. Because of which the other part of the moon is not visible to the people on Earth.
