Answer:
Explanation:
Moment of inertia of the metal rod pivoted in the middle
= M l² / 12
If the spring is compressed by small distance x twisting the rod by angle θ
restoring force by spring
= k x
moment of torque about axis
= k x l /2
= k θ( l /2 )² ( x / .5 l = θ )
=
moment of torque = moment of inertia of rod x angular acceleration
k θ( l /2 )² = M l² / 12 d²θ/dt²
d²θ/dt² = 3 k/M θ
acceleration = ω² θ
ω² = 3 k/M
ω = √ 3 k / M
Answer:
True
Explanation:
Pauli exclusion principle states that in an atom, no two electrons have same set of the quantum numbers. The electrons in an atom have a unique set of quantum numbers ,
Even the electron is in same shell, same subshell and same orbital, the spin quantum number will be different for the two of them.
For example : 2 electrons in
n = 2 , l = 1 , m = 1 but s is different for both of them . (+1/2 or - 1/2)
Answer:
you will get charge
Explanation:
Most shocks happen because you and the car have picked up opposite charges. Leaving your seat separates these charges, creating the potential for a static shock. Touching the metal of the car as you get out lets the charge balance out by flowing harmlessly through your hand
Hi Andrescruz9386
The ball in someone's hand is a balanced force because the object is staying in motion and is not changing at all so its evenly balanced, if its swinging back and fourth it is in motion and it wont stop till it becomes unbalanced, if the ball is just being held above the ground yes its balanced because nothing Is happening to it, its basically like a balance scale, if both sides are even and equal, than nothing will happen because there is no side that has more or less its equal so that's why its balanced, in order for it to be unbalanced it has to be brought upon unbalanced forces.
