Stressing an equilibrium simply means that the physical properties in which already exists are balanced. Stress can be applied by either changing the pressure or the volume or temperature.
Answer: 40 J
Explanation: Work is equal to the product of force and distance.
W = Fd
= 4N ( 10 m)
= 40 J
The formula is P = E/t, where P means power in watts, E means energy j , and t means time in seconds. This formula states that power is the consumption of energy per unit of time.
P = 15 M / 10*60
M = mega = 10⁶
15 *10⁶ / 600
= 25000 watt
In order to find the radius of the coin, we need to use:
Ac = V^2 r
In which,
Ac = acceleration of the coin = 2.2 m/s^2
V= rotational Speed = (18/12) * 2πr
r= Radius
so,
<span>2.2 = 9(π^2)(r^2) / r
</span><span>= 9(π^2)r
</span>
<span>r = 2.2 / 9(π^2) = 0.02476740044 m . . .or you can rounded it up to 0.025 m</span>
<span>Carbon atom showing 6 protons as electro positive charge in its nuclei should have same no of -ve charged electrons , that is 6 electronns in its radii to make an atom of C as a neutral element , for that each element in its atomic state should have equal no of protons and electrons , the no of neutrons which has no electric charge and almost negligible weight does play significant role except contributes to isotopes of the given atom or an element, so C atom having 6 protons should have 6 electrons</span>
