Going through the sums, we can list the given quantities as, speed v= 1500 m/s time in which the signal is recieved back after hitting the shoal, i.e time for going+time for coming back i.e 2t = 0.45 s therefore t = 0.225s To find distance d = ? Solution – velocity, distance and time can be…
We can list the given data as, frequency n = 170Hz wavelength λ = 2m To find speed v = ? Solution – velocity , frequency and wavelength is connected by the formula v = n x λ v = 170 x 2 v = 340 m/s The speed of sound is 340m/s
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…
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…
After going through the question, we can list some data as, workdone dW = 2000J isothermal process dU = 0 To find , Heat added dQ = ? Solution – From first law of thermodynamics we have dQ = dU + dW In the question it is given that the gas is taken through isothermal…
As per the given question, we can list out the given quantity Length L = 100 cm = 1m, mass m = 50 g = 50 x $10^{-3}$ kg displacement x = 3 cm = 0.03m , g = 9.8 m/$s^2$ To find = Restoring force, F = ? Solution – Restoring force, F =mg…
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…
Transverse Waves Definition – A wave in which particles of the medium vibrate in a direction perpendicular to the direction of propogation of wave is called as transverse waves .Example – Wave produced on rope. Characteristics of transverse waves👉 All particles of the medium in the path of the wave vibrate in the direction perpendicular…
Let us first start with defining what is a satellite. A satellite is a moon, planet or a machine that orbits a planet or star. Binding Energy for a satellite Since they are moving in an orbit, so definitely there is an energy that is keeping the satellite bounded with the planet. The minimum amount of…
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…
