Yo don’t click the link that guy says dude I think it’s like tracking or something
Answer:
<em><u>To be neutral</u></em>
Explanation:
Neutrons are electrically neutral but contribute to the mass of a nucleus to nearly the same extent as the protons. Neutrons can explain the phenomenon of isotopes (same atomic number with different atomic mass). The main role of neutrons is to reduce electrostatic repulsion inside the nucleus.
We will start from the definition of power in terms of the Force. Power could be described as the change of energy in an instant of time. Considering that Energy is the product between the Force and the distance traveled we would arrive at the expression
Here,
F = Force
h = Height
t = Time
As there is no external force, apart from the force of gravity, and this, is constant during the course of the object we will also have to be constant power and therefore this during its course will be the same. The correct answer is (1)
The formula used in calculations relating to transformers
is:
<span>Secondary voltage
(Vs)/ Primary voItage (VP) = Secondary turns (nS)/
Primary turns (nP)</span>
Substituting the
given values to find for Vs,
Vs / 120 V = 400
turns / 100 turns
<span>Vs = 480 V</span>
<span>It is the lowest velocity which a body must have in order to escape the gravitational attraction of a particular planet or other object.
Every planet has their own corresponding escape velocities. Example - Earth has escape velocity of 11.2 Km/s. It means, if you want to leave the Earth's gravitational field then it's the lowest speed which you need to acquire otherwise you wouldn't do that!
Hope this helps!</span>
