We know that frequency is an inverse value of time [tex]f=\dfrac{1}{t}[/tex] this implies that time is the inverse value of frequency [tex]t=\dfrac{1}{f}[/tex].
Now since f is 40kHz, we can calculate period or duration for that matter time.
[tex]t=\dfrac{1}{40\mathbf{kHz}}=0.000025\mathbf{s}=25\mathbf{\mu s}[/tex]
Hope this helps.

If you are performing an activity close to the ground, you are performing at a ______ level
Ans:
Low
Explanation:
Activities in physics are divided into 3 levels, depending on the distance from the ground (or the gravitational pull on the object)
LowMediumHighLow level (Low Plane) activities, as the name suggests, are performed at a lesser distance from the ground. Since the given statement mentions that the activity is performed closer to the ground, it will be the low level activity.
When an activity is described as being performed at a low level,
it means that it is taking place close to the ground or at a height that is not significantly above the ground.
This term is often used in contexts such as sports, exercise, or certain job tasks that require proximity to the ground.
For example, a low-level yoga pose would be one where the body is near the floor, or a low-level aerial maneuver would be performed close to the ground.
The antonym of this would be a high level, which indicates an activity performed at a considerable height above the ground.
How does the electrostatic force compare with the strong nuclear force in the nucleus of an atom?
A) The electrostatic force acts over short distances and is weaker.
B) The electrostatic force acts over long distances and is stronger.
C) The electrostatic force is only repulsive and acts over shorter distances.
D) The electrostatic force is only repulsive and acts over longer distances.
The electrostatic force is both attractive and repulsive and acts over long distances, while the strong nuclear force is a very powerful attractive force acting only over short distances within the atomic nucleus. The strong nuclear force is stronger than the electrostatic force and is responsible for the stability of the nucleus by binding protons and neutrons together.
Comparing the electrostatic force to the strong nuclear force within the nucleus of an atom, several key differences emerge. The electrostatic force can act over very large distances and can be either attractive or repulsive, depending on the charges involved. In contrast, the strong nuclear force is an extremely powerful attractive force that acts only over incredibly short distances, approximately 10-15 meters, which is about the scale of the atomic nucleus. This force is responsible for holding protons and neutrons together within the nucleus, overcoming the electrostatic repulsion between like-charged protons.
Examining the available choices:
(A) The electrostatic force acts over short distances and is weaker. Incorrect, the electrostatic force acts over long distances.(B) The electrostatic force acts over long distances and is stronger. Incorrect, the strong nuclear force is actually stronger.(C) The electrostatic force is only repulsive and acts over shorter distances. Incorrect, it can be both attractive and repulsive and acts over longer distances.(D) The electrostatic force is only repulsive and acts over longer distances. Partially correct, it is repulsive between like charges and does act over longer distances, but can also be attractive between opposite charges.The most accurate way to characterize these forces is that the strong nuclear force is a short-range but much stronger force, crucial for the stability of nuclei, while the electrostatic force, governed by Coulomb's law, has a longer range and is comparatively weaker than the strong nuclear force, but plays a critical role in interactions over larger distances and molecular bonding.
