After going through the question, we can list the data as
velocity v= 340m/s
wavelength λ = 1.7m
To find a) frequency n = ?
b) period T = ?
Solution –
velocity can be written as
v = n x λ
n = v / λ
n = 340 / 1.7 = 200 Hz
Also,
Time Period T = 1/n
T = 1/ 200 = 0.005 s
The method that we using here is of energy conservation. Let us assume the mass of the object as m kg Since the object is placed at height of 20 m above the ground, it possess potential energy . It is given by PE = m x g x h = 20 mg Let us…
Excessive use of mobile phones can have several side effects on both physical and mental health. Some of the common side effects include: 1. Eye strain and vision problems: Staring at the screen for long periods can lead to eye strain, dry eyes, blurred vision, and even nearsightedness. 2. Sleeping problems: The blue light emitted…
Physics is a subject that deals with the physical phenomenon occuring around us, be it on microscopic scale or macroscopic scale. It tries to explain us how the universe works & gives us an idea to build technology with the knowledge gained through it. Right from the discovery of electrons from heated cathode, that later got developed as…
Before knowing the types of vectors let us first understand what are vectors While learning physics we come across many physical quantities like momentum, speed, length, temperature etc. Now when we study them we need to represent them too. So for their representation we should know whether the quantity is a scalar quanitity or a…
After going through the question we can list some data as height h=200m density ρ = 1060 kg/m³ Atmospheric pressure P₀ = 1.013 x 10⁵ N/m² acceleration due to gravity g = 9.8m/s² To find, Pressure below 200m P = ? Solution – Absolute pressure , P = P₀ + ρgh P = 1.013 x…
A string tied to both ends can form stationary wave on it. The current setup is of Melde’s Experiment in parallel position. Here on loop is shown with two node(N) and one antinode(A) at the middle. Also the distance between two node is shown in the picture
