By looking at the acceleration of the object.
In fact, Netwon's second law states that the resultant of the forces acting on an object is equal to the product between the mass m of the object and its acceleration:
So, when static friction is acting on the object, if the object is still not moving we know that all the forces are balanced: in fact, since the object is stationary, its acceleration is zero, and so the resultant of the forces (left term in the formula) must be zero as well (i.e. the forces are balanced).

The frequency at which the body vibrates breaks is natural frequency. The glass with her voice because the frequency of her voice matches the natural frequency of the glass.
<h3>What is the natural frequency?</h3>When there is no external force acting on the body unless the body vibrates is known as the natural frequency of vibration.it is denoted by .
when the frequency of a body matches the natural frequency a condition occurs known as resonance.

Answer:
The formula is dimensionally correct.
Explanation:
Given
Required
Prove its correctness
Write out the dimension of each:
--- displacement
--- velocity * time
--- acceleration * square of time
The expression becomes:
Apply law of indices
Both sides of the equation are equal
